Low-friction arthroplasty of the hip using alumina ceramic and cross-linked polyethylene. A ten-year follow-up report. (1/596)

We report the results of our continued review of 14 hip arthroplasties using alumina ceramic femoral heads with cross-linked polyethylene cups. There have been no complications and a very low rate of penetration. This was 0.02 mm per year after an initial 'bedding-in' period of two years. There has been no change in the mean rate between our earlier study at six years and the current results at 10 to 11 years. The use of these bearing surfaces appears to reduce the potential amount of polyethylene debris and may provide the next logical stage in the development of the Charnley low-friction arthroplasty.  (+info)

Coating titanium implants with bioglass and with hydroxyapatite. A comparative study in sheep. (2/596)

This study compares the osteointegration of titanium implants coated with bioglass (Biovetro GSB formula) and with hydroxyapatite (HAP). Twenty-four bioglass-coated and 24 HAP-coated cylinders were implanted in the femoral diaphyses of sheep, and examined after 2, 4, 6, 8, 12, and 16 weeks. The HAP coating gave a stronger and earlier fixation to the bone than did bioglass. Bioglass formed a tissue interface which showed a macrophage reaction with little new bone formation activity. In contrast, HPA, showed intense new bone formation, with highly mineralised osseous trabeculae in the neighbourhood of the interface.  (+info)

Biological effects of naturally occurring and man-made fibres: in vitro cytotoxicity and mutagenesis in mammalian cells. (3/596)

Cytotoxicity and mutagenicity of tremolite, erionite and the man-made ceramic (RCF-1) fibre were studied using the human-hamster hybrid A(L) cells. Results from these fibres were compared with those of UICC Rhodesian chrysotile fibres. The A(L) cell mutation assay, based on the S1 gene marker located on human chromosome 11, the only human chromosome contained in the hybrid cell, has been shown to be more sensitive than conventional assays in detecting deletion mutations. Tremolite, erionite and RCF-1 fibres were significantly less cytotoxic to A(L) cells than chrysotile. Mutagenesis studies at the HPRT locus revealed no significant mutant yield with any of these fibres. In contrast, both erionite and tremolite induced dose-dependent S1- mutations in fibre-exposed cells, with the former inducing a significantly higher mutant yield than the latter fibre type. On the other hand, RCF-1 fibres were largely non-mutagenic. At equitoxic doses (cell survival at approximately 0.7), erionite was found to be the most potent mutagen among the three fibres tested and at a level comparable to that of chrysotile fibres. These results indicate that RCF-1 fibres are non-genotoxic under the conditions used in the studies and suggest that the high mesothelioma incidence previously observed in hamster may either be a result of selective sensitivity of hamster pleura to fibre-induced chronic irritation or as a result of prolonged fibre treatment. Furthermore, the relatively high mutagenic potential for erionite is consistent with its documented carcinogenicity.  (+info)

In vitro comparison of the retention capacity of new aesthetic brackets. (4/596)

Tensile bond strength and bond failure location were evaluated in vitro for two types of aesthetic brackets (non-silanated ceramic, polycarbonate) and one stainless steel bracket, using bovine teeth as the substrate and diacrylate resin as the adhesive. The results show that metallic bracket had the highest bond strength (13.21 N) followed by the new plastic bracket (12.01 N), which does not require the use of a primer. The non-silanated ceramic bracket produced the lowest bond strength (8.88 N). Bond failures occurred mainly between bracket and cement, although a small percentage occurred between the enamel-cement interface with the metal and plastic brackets and within the cement for the plastic bracket. With the ceramic bracket all the failures occurred at the bracket-cement interface. This suggests that the problems of enamel lesions produced by this type of bracket may have been eliminated. The results also show that the enamel/adhesive bond is stronger than the adhesive/bracket bond in this in vitro study.  (+info)

The crystal growth technique--a laboratory evaluation of bond strengths. (5/596)

An ex vivo study was carried out to determine differences in the bond strengths achieved with brackets placed using a crystal growth technique compared with a conventional acid-etch technique. A solution of 37 per cent phosphoric acid was used for acid-etching and a commercially available polyacrylic acid gel, Crystal-lok for crystal growth. A heavily-filled composite resin was used for all samples to bond brackets to healthy premolar teeth extracted for orthodontic purposes. Polycrystalline ceramic and stainless steel brackets were used and tested to both tensile and shear failure using an Instron Universal Testing machine. The tensile and shear bond strengths were recorded in kgF. In view of difficulties experienced with previous authors using different units to describe their findings, the data were subsequently converted to a range of units in order to facilitate direct comparison. The crystal growth technique produced significantly lower bond strengths than the acid-etch technique for ceramic and stainless steel brackets, both in tensile and shear mode. The tensile bond strength for stainless steel brackets with crystal growth was 2.2 kg compared with 6.01 kg for acid-etch, whilst with ceramic brackets the tensile bond strengths were 3.9 kg for crystal growth and 5.55 kg for acid-etch. The mean shear bond strength for stainless steel brackets with crystal growth was 12.61 kg compared with 21.55 kg for acid-etch, whilst with ceramic brackets the shear bond strengths were 7.93 kg with crystal growth compared with 16.55 kg for acid-tech. These bond strengths were below those previously suggested as clinically acceptable.  (+info)

Acute barium intoxication following ingestion of ceramic glaze. (6/596)

A case of deliberate overdose of barium sulphide in a psychiatric setting is presented, with resulting flaccid paralysis, malignant arrhythmia, respiratory arrest and severe hypokalaemia, but ultimately with complete recovery. The degree of paralysis appears to be related directly to serum barium levels. The value of early haemodialysis, particularly with respiratory paralysis and hypokalaemia, is emphasised.  (+info)

Dentinal tubule occlusion with lanthanum fluoride and powdered apatite glass ceramics in vitro. (7/596)

To simulate hypersensitive dentin, the smear layer and dentinal plugs of bovine root dentin specimens were removed by immersion in 10% phosphoric acid, polishing with hydroxyapatite particles, and ultrasonic cleansing. The fluoride-tannic acid-lanthanum-apatite (FTLA) group was treated with acidulated phosphate fluoride (APF) containing tannic acid followed by rubbing with a paste of lanthanum chloride (LaCl3) and powdered apatite glass ceramics. The treated specimens were immersed in a remineralizing solution that mimics saliva for 6 weeks. The SEM observations revealed that the treated surfaces of the FTLA group were completely covered with fine spherical compounds and the dentinal tubules were occluded with plugs to a depth of about 3 microns. Fluoride and lanthanum were detected to a depth of over 20 microns by EPMA observation. After the remineralization, the surface of FTLA-treated specimen did not have any opened tubules and showed a remarkable increase in the number of fine spherical deposits in the dentinal tubules. These results suggest that the reaction products produced by sequential treatment with acidic fluoride and LaCl3 and powdered apatite glass ceramics are able to effectively occlude dentinal tubules.  (+info)

Thermal image analysis of electrothermal debonding of ceramic brackets: an in vitro study. (8/596)

This study used modern thermal imaging techniques to investigate the temperature rise induced at the pulpal well during thermal debonding of ceramic brackets. Ceramic brackets were debonded from vertically sectioned premolar teeth using an electrothermal debonding unit. Ten teeth were debonded at the end of a single 3-second heating cycle. For a further group of 10 teeth, the bracket and heating element were left in contact with the tooth during the 3-second heating cycle and the 6-second cooling cycle. The average pulpal wall temperature increase for the teeth debonded at the end of the 3-second heating cycle was 16.8 degrees C. When the heating element and bracket remained in contact with the tooth during the 6-second cooling cycle an average temperature increase of 45.6 degrees C was recorded.  (+info)

A method for producing high surface area, thermally stable, microporous porous ceramic materials involves replacing a portion of the silicon in a sol or gel comprising silica (silicon dioxide) with cations of another metal. The metal-substituted silica sols are dried and fired to yield porous ceramic materials. Similarly, metal-substituted gels are fired to yield porous ceramic materials. When compared with unsubstituted silica materials, the materials thus produced offer advantageous benefits including improved stability in a basic environment, enhanced thermal stability, and advantageous surface properties such as intrinsic negative charge.
Efficient delivery of growth factors from carrier biomaterials depends critically on the release kinetics of the proteins that constitute the carrier. Immobilizing growth factors to calcium phosphate ceramics has been attempted by direct adsorption and usually resulted in a rapid and passive release of the superficially adherent proteins. The insufficient retention of growth factors limited their bioavailability and their efficacy in the treatment of bone regeneration. In this study, a coprecipitation technique of proteins and calcium phosphate was employed to modify the delivery of proteins from biphasic calcium phosphate (BCP) ceramics. To this end, tritium-labeled bovine serum albumin ([3H]BSA) was utilized as a model protein to analyze the coprecipitation efficacy and the release kinetics of the protein from the carrier material. Conventional adsorption of [3H]BSA resulted in a rapid and passive release of the protein from BCP ceramics, whereas the coprecipitation technique effectively ...
Bioglass 45S5, commonly referred to by its commercial name Bioglass, is a glass specifically composed of 45 wt% SiO2, 24.5 wt% CaO, 24.5 wt% Na2O, and 6.0 wt% P2O5. Glasses are non-crystalline amorphous solids that are commonly composed of silica-based materials with other minor additives. Compared to soda-lime glass (commonly used, as in windows or bottles), Bioglass 45S5 contains less silica and higher amounts of calcium and phosphorus. The 45S5 name signifies glass with 45 weight % of SiO2 and 5:1 molar ratio of calcium to phosphorus. This high ratio of calcium to phosphorus promotes formation of apatite crystals; calcium and silica ions can act as crystallization nuclei. Lower Ca:P ratios do not bond to bone. Bioglass 45S5s specific composition is optimal in biomedical applications because of its similar composition to that of hydroxyapatite, the mineral component of bone. This similarity provides Bioglass ability to be integrated with living bone. This composition of bioactive glass is ...

PURPOSE & DESIGN:. The investigators are currently following up a cohort of patients all of whom have had a metal on ceramic total hip arthroplasty.. This new bearing couple has been approved for use in the UK for some time and has recently achieved USA FDA approval.. The attraction of this bearing couple is a low rate of wear with reduced complications associated with ceramic on ceramic bearing such as bearing fracture.. Of recent media attention has been the unacceptably high failure of the DePuy ASR metal on metal hip resurfacing. This metal on metal bearing couple has been associated with increased ion levels and chromosome abnormalities in vivo.. In vitro studies and small in vivo studies have revealed much lower wear, particle numbers and ion levels in ceramic on metal studies than in metal on metal bearing surfaces; however there is no large scale evidence that this is the case.. The investigators currently are following up the largest worldwide series of ceramic on metal bearings and ...
Mit ceramic implants - international magazine of ceramic implant technology publiziert die OEMUS MEDIA AG seit 2017 ein neues englischsprachiges Fachmagazin.. 40 Jahre lang haben sich Implantate aus Titan hervorragend als Zahnimplantate bewährt. Auch wenn die Anfänge der Implantologie schon einmal metallfrei waren, hat sich das damals zur Verfügung stehende Material „Aluminiumoxid-Keramik" aus Stabilitätsgründen nicht bewährt. Heute ist Zirkonoxid als Implantatmaterial anerkannt, Stabilität, Osseointegration und prothetische Möglichkeiten sind zunehmend mit Titan auf einer Stufe zu sehen. Die Nachfrage nach dem hochästhetischen, gewebefreundlichen, antiallergischen und metallfreien Material Zirkonoxid steigt. Dies v. a. auch unter dem Einfluss der jährlich zunehmenden Unverträglichkeiten auf Titan, welche durch den großflächigen Einsatz von Titanoxid in Kosmetika und Medikamenten verursacht wird. Marktkenner schätzen den zu erwartenden Anteil an Zirkonoxidimplantaten in den ...
... ARE AN ALTERNATIVE TO organic or polymer based coatings for selected surface coating applications. When protecting a surface, it is usually less expensive to use organic coatings rather than other materials such as ceramic coatings. However, organic paints have limitations and will not meet all service requirements. Though more expensive, for some applications ceramic coatings may be a more suitable form of protection. Vitreous (glassy) ceramic coatings are chosen for application over a substrate for one or more of several reasons [1]. These reasons for selecting a ceramic coating in preference to an organic paint include rendering the surface more chemically inert, impervious to liquids and gases, more readily cleanable, and more resistant to service temperature, abrasion, and scratching. The chemical durability of ceramic coatings in service substantially exceeds that of organic paints [2]. Vitreous coatings are formulated to be resistant to a variety of reagents, from acids ...
In an effort to develop chemically bonded phosphate ceramics for mixed waste stabilization, a collaborative project to develop iron-phosphate based ceramics has been initiated between Argonne National Laboratory and the V. G. Khlopin Radium Institute in St. Petersburg, Russia. The starter powders are oxides of iron that are generated as inexpensive byproduct materials in the iron and steel industry. They contain iron oxides as a mixture of magnetite (Fe{sub 3}O{sub 4}) and haematite (Fe{sub 2}O{sub 3}). In this initial phase of this project, both of these compounds were investigated independently. Each was reacted with phosphoric acid solution to form iron phosphate ceramics. In the case of magnetite, the reaction was rapid. Adding ash as the waste component containing hazardous contaminants resulted in a dense and hard ceramic rich in glassy phase. On the other hand, the reaction of phosphoric acid solution with a mixture of haematite and ash waste contaminated with cesium and americium was too slow.

Thick opaque ceramic coatings are used to protect delicate microelectronic devices against excited energy sources, radiation, light, abrasion, and wet etching techniques. The thick opaque ceramic coating are prepared from a mixture containing phosphoric anhydride, i.e., phosphorous pentoxide (P2 O5), and a pre-ceramic silicon-containing material. It is preferred to also include tungsten carbide (WC) and tungsten metal (W) in the coating mixture. The coating is pyrolyzed to form a ceramic SiO2 containing coating. A second coating of plasma enhanced chemical vapor deposited (PECVD) silicon carbide (SiC), diamond, or silicon nitride (Si3 N4), can be applied over the thick opaque ceramic coating to provide hermeticity. These coatings are useful on patterned wafers, electronic devices, and electronic substrates. The thick opaque ceramic coating is unique because it is resistant to etching using wet chemicals, i.e., acids such as H3 PO4 and H2 SO4, or bases.
This thesis concerns factors controlling the grain morphology in Si|sub>3|/sub>N|sub>4|/sub> and Al|sub>2|/sub>O|sub>3|/sub> based ceramics.

Bone related diseases and disorders are a significant socioeconomic burden in the United States. Autografts and allografts are most commonly used for the treatment of bone defects and non-unions; however, they are associated with limitations such as donor site morbidity and immune rejection, respectively. Over the past few decades, bone tissue engineering (BTE) using scaffold and cells has garnered significant interest as an alternative method for the repair and regeneration of bone defects. Recreation of the tissue microenvironment via the development of biomimetic scaffolds that resemble the physicochemical aspects (i.e., composition, topography, stiffness) of native bone is a promising approach that has been previously shown to improve scaffold properties and augment cellular response. In this realm, collagen type I and bioactive glass (Bioglass 45S5 (BG); an osteostimulative glass-ceramic) have been combined in numerous studies to generate hybrid scaffolds that mimic the organic and ...
Various types of grafts have been traditionally used to restore damaged bones. In the late 1960s, a strong interest was raised in studying ceramics as potential bone grafts due to their biomechanical properties. A bit later, such synthetic biomaterials were called bioceramics. In principle, bioceramics can be prepared from diverse materials but this review is limited to calcium orthophosphate-based formulations only, which possess the specific advantages due to the chemical similarity to mammalian bones and teeth. During the past 40 years, there have been a number of important achievements in this field. Namely, after the initial development of bioceramics that was just tolerated in the physiological environment, an emphasis was shifted towards the formulations able to form direct chemical bonds with the adjacent bones. Afterwards, by the structural and compositional controls, it became possible to choose whether the calcium orthophosphate-based implants remain biologically stable once incorporated into
There is great need to purify the contaminated water which the poor people in Africa have access to, and make it safe for drinking in a way that is affordable and effective. A particular challenge is the removal of pathogenic bacteria and viruses, which traditionally are eliminated by expensive nano-filtration or reverse osmosis. An added requirement is satisfying the recent recommendation of the WHO for household water-treatment systems to eliminate 99.99% of microbial contamination, which is proving exceptionally difficult to achieve in poor countries at a cost they can afford. We report on the successful testing of a low-cost, locally produced ceramic filter that has the potential to meet the WHO criterion at a cost of US$10 per year. In one version the filter consisted of a silver-impregnated, highly porous ceramic; in another modification silver nano particles were incorporated on the ceramic surface. The silver-impregnated filter was tested on water samples contaminated with selected Gram ...

Sintering process is a complex of different synergetic effects during the ceramics materials consolidation. The microstructural level properties control is very important as a stage in advanced materials prognosis. SEM analysis of Yb/BaTiO3 doped ceramics showed that in samples doped with a low level of dopant and sintered at higher temperatures the grain size ranged from 10-60μm, while with the higher dopant concentration the grain size ranged between 2-15μm. The morphology of sintered BaTiO3-ceramics grains points out the validity of developing new structure analytical methods based on different geometries of grains model systems. The idea of electrical properties of BaTiO3-ceramics being influenced by intergrain microcontacts can be successfully followed if we start with the two-sphere Cobles model and also the correction of the Cobles model. In this paper, the grains contact models based on spherical, ellipsoidal and polyhedral geometries are presented making a new modeling tool... for ...

Background Surface treatments and irregularities in the surfaces may affect the fracture of ceramics. The effects of various treatments on the surface texture of different types of ceramic cores/substructures was therefore qualitatively, quantitatively and numerically evaluated. Since fractures in ceramics are not fully understood, the fracture behavior in dental ceramic core/substructures was also studied using both established laboratory methods and newly developed numerical methods.. Methods The surfaces of dental ceramic cores/substructures were studied qualitatively by means of a fluorescence penetrant method and scanning electron microscopy, quantitatively evaluated using a profilometer and also numerical simulation. In order to study fracture in zirconia-based fixed partial denture (FPD) frameworks, fractographic analysis in combination with fracture tests and newly developed two-dimensional (2D) and three-dimensional (3D) numerical modeling methods were used. In the numerical modeling ...
By 1700 many of the potteries elsewhere in the Midlands had ceased production. Since Stoke-on-Trents supply of pots exceeded the demand of nearby markets, potters here developed a network of merchants who distributed and sold their wares over a large area.. Low wages and living costs meant that pots could be produced more cheaply than in other areas. Of the pottery-making centres in the country, Stoke-on-Trent alone continued its growth to become the only industrial area in Britain to become known by the name of its principal trade - The Potteries.. By 1740, the pottery industry was truly established in Stoke-on-Trent, but the local clays that could be found in the area were not favoured by potters because they fired red - potters wanted white clays that were as similar as possible to the china from the Far East.. The raw materials of the craft were sought further and further afield to supply the pottery industry. White burning clays from Dorset had begun to be brought into Stoke-on-Trent ...

Long-term mechanical reliability is a key issue in their ultimate use for a specific application. Correlations between processing and service conditions/environment to failure of ceramics by fracture, fatigue or deformation are key aspects of materials applications. This track covers Mechanics, Characterization Techniques, and Equipment, Tribology and Wear, Environmental Effects, Reliability and Small Scale Testing, Mechanical Behavior of CMCs, Processing - Microstructure - Mechanical Properties Correlation.. Ceramics cover a very wide range of materials from structural materials like concrete to technical ceramics like PZT - a piezoelectric. Usually they are defined as solids with a mixture of metallic or semi-metallic and non-metallic elements (often, although not always, oxygen), that are quite hard, non-conducting and corrosion-resistant. Composites are often used in applications that require specific conflicting properties such as a high strength and high toughness. The properties may be ...

Ponitless sidegrade. Ceramic bearings make sense if they have a ceramic race but only the very expensive hard to find ones do. Most ceramic bearings are a hybrid of steel races and ceramic balls. Grade 10 chrome or stainless ball is all anyone ever needs in a bearing. There is no power saving for using ceramic bearings, those that claim that are lying or comparing to a nrelaisticly draggy hub. Any decent hub will be absorbing less than 1W at high speed. The weight saving is small too. Not really worth it unless you are bored and have some spare cash. I have done plenty of thing for those too reasons alone ...

Changing fuel form factor when adding new fuel can cause stalling. The group discussed in detail the following ideas for advancing TLUD development:. **Materials:** light-weight ceramics are not necessarily needed for insulation of the combustion chamber, unlike in a rocket stove, as for TLUDs the temperature in the fuel bed stays at ambient temperature until the pyrolysis front passes through. Then temperatures get higher. The open flames are not within the combustion chamber but above the fuel bed. The hottest parts of a TLUD stove are the concentrator disk and the bottom of the fire chamber, where the remaining charcoal might be burnt creating high temperatures (if the char is not dumped out and conserved for other use e.g. as biochar). Ceramics are cheap to fabricate, e.g. consumable stove components like the concentrator disk or the bottom plate of the fire chamber. Options for modular stove designs containing ceramic parts to be explored further. A huge gap between standard pottery and ...

A minimally invasive prosthetic procedure (MIPP) for the esthetic rehabilitation of the complete arch advocates the preservation of enamel to optimize the adhesive bond of the luting agent to both the tooth surface and the etchable ceramic restoration. When esthetic rehabilitation of a worn dentition is required, a MIPP can be selected to reduce the biological cost of removing additional enamel tooth structure. The fundamental steps to achieve this goal are to: (1) increase the vertical dimension of occlusion (VDO); (2) reduce the thickness of the monolithic ceramic material; (3) preserve the enamel during tooth preparation; and (4) adhesively bond the etchable ceramic restorations. This article presents a comprehensive, minimally invasive prosthetic treatment approach for the esthetic rehabilitation of a severely worn dentition using a lithium disilicate all-ceramic material with partial and complete coverage restorations ...

Chevron-notched bend specimens in three-point loading are increasingly used for evaluation of fracture toughness of structural ceramics. Its advantages include stable precracking of the specimen during loading, a simple specimen geometry, and a compressive mode of loading that is convenient for testing ceramics at elevated temperatures. Subcritical crack growth caused by environmental interactions or mass transport phenomena at elevated temperatures, however, can affect the apparent fracture toughness measured. A numerical computational study was carried out to assess the effects of subcritical crack growth on crack stability in the chevron-notched three-point bend specimens. A power-law relationship between the sub-critical crack velocity (v) and the applied stress intensity (K I ) was used along with compliance and stress-intensity relationships for the chevron-notched bend specimen to calculate the load response under fixed deflection rate and a machine compliance. The results indicate that ...
Lightweight, monolithic ceramics resistant to oxidation in air at high temperatures are made by impregnating a porous carbon preform with a sol which contains a mixture of tetraethoxysilane, dimethyldiethoxysilane and trimethyl borate. The sol is gelled and dried on the carbon preform to form a ceramic precursor. The precursor is pyrolyzed in an inert atmosphere to form the ceramic which is made of carbon, silicon, oxygen and boron. The carbon of the preform reacts with the dried gel during the pyrolysis to form a component of the resulting ceramic. The ceramic is of the same size, shape and form as the carbon precursor. Thus, using a porous, fibrous carbon precursor, such as a carbon felt, results in a porous, fibrous ceramic. Ceramics of the invention are useful as lightweight tiles for a reentry spacecraft.

Ceramic engineering is the science and technology of creating objects from inorganic, non-metallic materials. This is done either by the action of heat, or at lower temperatures using precipitation reactions from high-purity chemical solutions. The term includes the purification of raw materials, the study and production of the chemical compounds concerned, their formation into components and the study of their structure, composition and properties. Ceramic materials may have a crystalline or partly crystalline structure, with long-range order on atomic scale. Glass ceramics may have an amorphous or glassy structure, with limited or short-range atomic order. They are either formed from a molten mass that solidifies on cooling, formed and matured by the action of heat, or chemically synthesized at low temperatures using, for example, hydrothermal or sol-gel synthesis. The special character of ceramic materials gives rise to many applications in materials engineering, electrical engineering, ...

In the early 1980s, Toyota researched production of a ceramic engine that could run at a temperature above 6,000 °F (3,300 °C). Ceramic engines do not require a cooling system and hence permit major weight reduction and higher fuel efficiency. In a conventional metallic engine, much of the energy released by combustion of the fuel must be dissipated as waste heat, to prevent the metallic parts from melting. Despite these desirable properties, such engines are not being mass-produced because it is difficult to manufacture ceramic parts with the requisite precision and durability. Imperfections in the ceramic material can lead to cracks and potentially dangerous equipment failure.. Efforts are being made to develop ceramic parts for gas turbine engines. Currently, even blades made of advanced metal alloys for the hot section of an engine require cooling and careful limiting of operating temperatures. Turbine engines made with ceramics could operate more efficiently, giving aircraft greater range ...

0043]For ceramizing and simultaneously burning in the decoration, this end of the substrate with the layer 5 and the decorative ink applied thereon is put into a ceramizing oven 30. During ceramization in the oven 30, the glass substrate 1 becomes soft so that even minor forces acting on the substrate 1 lead to undesired deformations. During ceramization typically at 900° C. or above, for instance, 5 viscosities of less than c=101 dPas can be reached. Shrinkage of the substrate furthermore takes place during the ceramization. The flame-pyrolytically deposited layer 5 does not cause any relevant thermal stresses, in contrast for instance to thicker sol-gel layers as obtained by the method known from DE 3936654 C1, so that deformation is avoided. The silicate layer 5 with the high density of terminal OH groups furthermore ensures improved adhesion of the decoration after burning in, i.e. ceramizing. During the ceramization, the green glass substrate is conventionally placed on a support, ...

Metal-to-polyethelene hip transplants have done yoemans work for most patients, but after about 15 years, the metal begins to wear the plastic down, creating in some patients, osteolysis in the hip, which occurs when particles break off from the implant," said Dr. Steven Gitelis, orthopedic surgeon at Rush. He is one of the few orthopedic surgeons in Chicago testing the ceramic implant as part of a research protocol that may lead to more extensive use of the ceramic hip implants. "With more people living longer, the expectation is that hip replacements should last longer, too," he added ...
We have porous ceramic platelets of ~50x5x1 mm³ thickness infiltrated with ammonium nitrate solution (NH4NO3). We want to decompose and evaporate it w/o damaging the fragile substrate (decomposition should take place at ~210 °C). Since this is part of a repeated experimental procedure, it shouldnt take longer than ~15 minutes for heating, decomposition and cooling back to max ~50 °C for a batch of 10 to 20 samples at once.. I was thinking about a microwave furnace since it would heat only the samples, or maybe even only the ammonium nitrate within the samples (not sure how well ceramics (ZrO2) couples in the µwave), but since it will heat the material uniformly, Im concerned about explosive evaporation and damage of the fragile samples. Might still be suitable if the power is tuned well.. What also came to my mind was inductive heating of a small metal sample carrier or sample holding capsule. Could also be quick. However I have no idea if lab devices like this are available, at least Ive ...
abstract = {A method is proposed for evaluating the potential piezoelectric response, that a ferroelectric material would exhibit after full poling, from elastic and dielectric measurements of the unpoled ceramic material. The method is based on the observation that the softening in a ferroelectric phase with respect to the paraelectric phase is of piezoelectric origin, and is tested on BaTiO3. The angular averages of the piezoelectric softening in unpoled ceramics are calculated for ferroelectric phases of different symmetries. The expression of the orientational average with the piezoelectric and dielectric constants of single crystal tetragonal BaTiO3 from the literature reproduces well the softening of the Youngs modulus of unpoled ceramic BaTiO3, after a correction for the porosity. The agreement is good in the temperature region sufficiently far from the Curie temperature and from the transition to the orthorhombic phase, where the effect of fluctuations should be negligible, but ...

Several studies demonstrated that the use of graft material has better clinical results for the treatment of intrabony defects. The purpose of this study is to compare the clinical and radiographic efficacy of alloplast (Biphasic calcium phosphate) and demineralized freeze-dried bone allograft (DFDBA) in treatment of periodontal intraosseous defects. A split mouth study was conducted in 20 subjects diagnosed with chronic periodontitis presenting atleast two intrabony defects in either arch. One quadrant (Site A) received alloplast (Biphasic calcium phosphate) and the contralateral defect (Site B) received DFDBA. The results of study showed that clinically Site B (DFDBA) showed greater reduction in pocket depth and gain in clinical attachment level than site A (Biphasic calcium phosphate), however it was not statistically significant. Site A (Biphasic calcium phosphate) showed slightly more gingival marginal recession than Site B (DFDBA). Radiographically Site B (DFDBA) showed greater bone fill ...

Objectives The current recommended protocol for bonding zirconia restorations to teeth involves the use of an adhesive system containing phosphate monomers. But there is limited evidence that phosphate monomer produces a bond comparable to an etched silanised glaze layer on zirconia. This study evaluated the effect of using an etched and silanised glazed porcelain layer on the interfacial fracture toughness between a zirconia ceramic and resin cements. The effect of a phosphate monomer primer on resin bond to glazed zirconia was also used in this study. Methods Forty rectangular-shaped yttrium stabilised zirconia ceramic plates (VITA In-Ceram YZ, VITA, Bad Sackingen, Germany) (length: 20mm; width: 7mm; thickness 2mm) were sintered prior to air abrasion with 100 µm Al2O3 at two bar pressure. Twenty specimens were glazed with Akzent Glaze Spray (VITA Zahnfabrik; Bad Sackingen, Germany) and then etched with 9% hydrofluoric acid for 180 seconds prior to being silanised with Monobond-S (Ivoclar ...

The aim of this study was a retrospective assessment of the up to 8-year clinical outcomes of zirconia ceramic single-retainer resin-bonded fixed dental prostheses (RBFDPs). Fifteen subjects (9 women, 6 men) with 15 anterior zirconia ceramic RBFDPs were included. The RBFDPs replaced 5 maxillary central incisors, 7 maxillary lateral incisors, and 3 mandibular lateral incisors. The patients willing to participate were recalled and the survival of the RBFDPs was assessed. The technical outcome was evaluated with modified United States Public Health Service criteria. Fracture and/or chipping of the restoration, occlusal wear, marginal adaptation, marginal discoloration, shape, surface texture, and esthetic integration were recorded. Biologic parameters were assessed, including vitality, probing pocket depth, gingival recession, plaque control record, bleeding on probing, and periodontal mobility. Data were descriptively analyzed using a paired t test (P , .05). Fifteen subjects with 15 RBFDPs were ...
Materials and Methods: A pencil-type APP torch was used to modify the surface chemical composition and hydrophilicity of dental ceramic and to improve the adhesion of composite resin to the surface. The effect of the applied power on chemical changes of the plasma polymer on a ceramic surface and the adhesive strength between the composite resin and feldspathic porcelain were examined. Adhesion was evaluated by comparing shear bond strengths (SBS) using the iris method. The chemical composition of the plasma polymer deposited on the ceramic surface was evaluated using x-ray photoelectron spectroscopy (XPS). Hydrophilicity was evaluated by contact angle measurements. The fracture mode at the interface was also evaluated ...

Houses were built by digging a rounded rectangular pit a few feet deep. Then they were rammed, and a lattice of wattle was woven over it. Then it was plastered with mud. The floor was also rammed down. Next, a few short wattle poles would be placed around the top of the pit, and more wattle would be woven to it. It was plastered with mud, and a framework of poles would be placed to make a cone shape for the roof. Poles would be added to support the roof. It was then thatched with millet stalks. There was little furniture; a shallow fireplace in the middle with a stool, a bench along the wall, and a bed of cloth. Food and items were placed or hung against the walls. A pen would be built outside for animals. Yangshao villages typically covered ten to fourteen acres and were composed of houses around a central square.[6] ...
