Initial orthopaedic displacement compared with longitudinal displacement of the maxilla after a forward force application. An experimental study in dogs. (1/236)

The aim of this study was to compare the initial orthopaedic displacement of the maxilla in vivo and the longitudinal changes after a forward force application. The sample consisted of five 1-year-old dogs. An anterior force of 5 N on the maxilla was applied by a coil spring system pushing between Branemark implants and a maxillary splint. The initial displacement of the maxilla after force application was measured by means of speckle interferometry. The longitudinal displacement of the maxilla after a force application during 8 weeks was measured by superimposing standardized lateral cephalograms. The initial, as well as the longitudinal, displacement of the maxilla of the dogs was in a forward direction with some counterclockwise rotation. There was no statistical difference between the initial and longitudinal displacement. The biological response after force application during 8 weeks can be predicted by the initial orthopaedic displacement.  (+info)

The fixation of the cemented femoral component. Effects of stem stiffness, cement thickness and roughness of the cement-bone surface. (2/236)

After cemented total hip arthroplasty (THA) there may be failure at either the cement-stem or the cement-bone interface. This results from the occurrence of abnormally high shear and compressive stresses within the cement and excessive relative micromovement. We therefore evaluated micromovement and stress at the cement-bone and cement-stem interfaces for a titanium and a chromium-cobalt stem. The behaviour of both implants was similar and no substantial differences were found in the size and distribution of micromovement on either interface with respect to the stiffness of the stem. Micromovement was minimal with a cement mantle 3 to 4 mm thick but then increased with greater thickness of the cement. Abnormally high micromovement occurred when the cement was thinner than 2 mm and the stem was made of titanium. The relative decrease in surface roughness augmented slipping but decreased debonding at the cement-bone interface. Shear stress at this site did not vary significantly for the different coefficients of cement-bone friction while compressive and hoop stresses within the cement increased slightly.  (+info)

Comparison of in vivo wear between polyethylene liners articulating with ceramic and cobalt-chrome femoral heads. (3/236)

At yearly intervals we compared the radiological wear characteristics of 81 alumina ceramic femoral heads with a well-matched group of 43 cobalt-chrome femoral heads. Using a computer-assisted measurement system we assessed two-dimensional penetration of the head into the polyethylene liner. We used linear regression analysis of temporal data of the penetration of the head to calculate the true rates of polyethylene wear for both groups. At a mean of seven years the true rate of wear of the ceramic group was slightly greater (0.09 mm/year, SD 0.07) than that of the cobalt-chrome group (0.07 mm/year, SD 0.04). Despite the numerous theoretical advantages of ceramic over cobalt-chrome femoral heads, the wear performance in vivo of these components was similar.  (+info)

Influence of finishing on the electrochemical properties of dental alloys. (5/236)

Dental alloy surface finishing procedures of may influence their electrochemical behavior, which is used to evaluate their corrosion resistance. We examined the polarization resistance and potentiodynamic polarization profile of the precious-metal alloys, Type 4 gold alloy and silver-palladium alloy, and the base-metal alloys, nickel-chromium alloy, cobalt-chromium alloy, and CP-titanium. Three types of finishing procedure were examined: mirror-finishing using 0.05 micron alumina particles, polishing using #600 abrasive paper and sandblasting. Dissolution of the alloy elements in 0.9% NaCl solution was also measured and compared with the electrochemical evaluation. The corrosion resistance of the dental alloys was found to relate to finishing as follows: The polarization resistance and potentiodynamic polarization behavior revealed that the corrosion resistance improved in the order of sandblasting, #600-abrasive-paper polishing, and mirror-finishing. While the corrosion potential, critical current density and passive current density varied depending on the type of finishing, the transpassive potential remained unchanged. The influence of finishing on the corrosion resistance of precious-metal alloys was less significant than on that of base-metal alloys. A mirror-finishing specimen was recommended for use in evaluation of the corrosion resistance of various dental alloys.  (+info)

Effect of the adhesive layer thickness on the fracture toughness of dental adhesive resins. (6/236)

We investigated how the thickness of an adhesive layer between two Co-Cr alloy plates affected the mode I fracture toughness of dental adhesive resin by varying the type of resin using a double cantilever beam (DCB) test. Two typical adhesive resins (PV and SB) were used. The adhesive layers of the DCB test specimens were 20, 100 and 200 microns thick. The fracture modes of PV differed with the thickness of the adhesive layer, such as interface fracture at 20 microns thickness, and similar cohesive fracture at 100 and 200 microns thickness. In the case of SB, crack-propagating areas were observed as cohesive fractures in all test specimens with different adhesive layer thickness, and the surfaces of these areas became remarkably rougher as the thickness of the adhesive layer increased. The fracture toughness of PV was not affected by the differences in thickness between the 100 and 200 microns adhesive layers, but there was a notable decrease in fracture toughness when the adhesive layer decreased to a thickness of 20 microns. That of SB showed a tendency to increase as the adhesive layer became thicker.  (+info)

The laser welding technique applied to the non precious dental alloys procedure and results. (7/236)

AIM: The laser welding technique was chosen for its versatility in the repair of dental metal prosthesis. The aim of this research is to assess the accuracy, quality and reproducibility of this technique as applied to Ni-Cr-Mo and Cr-Co-Mo alloys often used to make prosthesis METHOD: The alloy's ability to weld was evaluated with a pulsed Nd-Yag Laser equipment. In order to evaluate the joining, various cast wires with different diameters were used. The efficiency of the joining was measured with tensile tests. In order to understand this difference, metallographic examinations and X-Ray microprobe analysis were performed through the welded area and compared with the cast part. RESULTS: It was found that a very slight change in the chemistry of the Ni-Cr alloys had a strong influence on the quality of the joining. The Co-Cr alloy presented an excellent weldability. A very important change in the microstructure due to the effect of the laser was pointed out in the welding zone, increasing its micro-hardness. CONCLUSION: The higher level of carbon and boron in one of the two Ni-Cr was found to be responsible for its poor welding ability. However for the others, the maximum depth of welding was found to be around 2mm which is one of the usual thicknesses of the components which have to be repaired.  (+info)

Influence of polyethylene and femoral head surface quality on wear: a retrieval study. (8/236)

Thirty-two polyethylene sockets and 22 femoral heads were retrieved because of aseptic loosening more than 9 years after total hip arthroplasty. The volumetric wear rates of the retrieved polyethylene sockets were significantly greater in those coupled with an alumina head (P < 0.05). The retrieved alumina heads showed significantly better surface roughness and roundness than heads of Co-Cr and of stainless steel (P < 0.05). However, no significant difference was found in polyethylene quality demonstrated as fusion defects among the three different groups. The present study suggests that maintaining better surface roughness and roundness of the femoral heads does not always result in an in vivo reduction of polyethylene wear.  (+info)

Both the spin- and charge-density waves of Cr alloys are produced by the Coulomb attraction between electrons and holes on nearly nested Fermi surfaces. Driven by quasi-particle transitions, transverse spin- wave and longitudinal phason modes are associated with rotational and translational symmetries of pure Cr and its dilute alloys. At low frequencies, both spin and charge phasons have a nearly linear dispersion with a mode velocity which approaches the spin-wave velocity as T approaches T{sub N} or as the mismatch between the Fermi surfaces increases.
PMID: 16752620 Purpose: This study aimed to investigate the release of nickel, copper, zinc, cadmium, magnesium, and lead from prosthodontic base metal alloys into protein-containing biologic solutions. Materials and Methods: Dissolution experiments were conducted in either 3% Dulbecco s Modified Eagle Medium or 3% bovine serum albumin solutions for 7 weeks. Results: The protein-containing dissolution solutions and dissolution time did not have a significant effect on release of elements from the alloys (Kruskal-Wallis, P > .05). Conclusions: The amount of the released elements was well below the dietary intake levels of these elements. This study is important given the widespread use of the base metal alloys and the continuing public concerns/questions regarding the health benefits/risks associated with these materials.

This first-in-human study was designed to examine the temporal patterns of tissue healing and the proof-of-concept for restoration to a BMS. We chose 4 months post stent deployment as the first assessment point because the polymer coating is completely absorbed at ∼3 months. Repeated imaging at 6, 8, and 18 months allowed a detailed assessment of the tissue strut coverage, strut malapposition, positive remodeling, and other changes that have been associated with some of the durable polymer DES.. Our study confirmed, up to 18 months, the preliminary safety and efficacy of the cobalt chromium thin-strut MiStent SES, from which a poly lactide-co-glycolic acid polymer coating is absorbed in 45 to 60 days. Crystalline sirolimus is delivered locally in sustained, therapeutic concentrations up to 6 months, without initial burst. The small angiographic in-stent LLL at each time point, along with the low neointimal volume obstruction on IVUS, indicates stent efficacy. Of particular interest, and in ...

Currently available stents were designed for straight lesions, optimised to provide scaffolding (coverage and radial strength) and ease of deliverability. In straight lesions, these stents have been shown to provide superb acute and long-term results. One lesion subset that continues to challenge the interventionalist is bifurcations lesions. A number of different strategies have been employed with standard stents to address bifurcation lesions each of which have significant limitations. Large contemporary registries characterising current stent usage in bifurcating lesions have demonstrated decreased procedural success with increased rates in restenosis and thrombosis (acute, subacute and delayed). The limitations of currently available stents have led groups to develop stents designed specifically to treat bifurcation lesions. The Tryton Side-Branch Stent Stent TM (Tryton Medical, Inc., Newton, MA, USA) is a balloon expandable cobalt chromium stent, designed specifically to treat bifurcation ...

The common component in both systems-and what is at the heart of the lawsuits-is the Conserve cup, which is a cast cobalt chromium molybdenum piece that holds the metal femoral head, mimicking the natural movement of a hip joint. It is that unlined cobalt part that is allegedly causing serious harmful effects to patients who receive the implant device. The problem is that these two metal components cause the release of metal particles around the hip joint and surrounding tissue. As a result, a high percentage of patients have developed metallosis and biologic toxicity and are experiencing a high and early failure rate of the device ...

Dental Gold and Gold Alloys. Gold, the most noble of metals, seldom tarnishes or corrodes in the oral cavity. Because of the softness of pure gold, it is not indicated for use in the mouth except in the form of gold foil. Gold is frequently used in combination with other metals to produce alloys that can be used to fabricate various types of dental restorations where metal is indicated. The basic types of gold alloys used in dentistry are casting gold, gold solder, wrought gold, and gold plate. The principal metals used to combine with gold to form the alloys are silver, copper, platinum, palladium, and zinc. ADMINISTRATIVE CONTROL Controlled items subject to strict accountability and safeguarding are gold solder, platinum foil, and gold, silver, and chromium alloys. In addition, scrap from these controlled items and from amalgam are also subject to the same controls. Certain delegated members of a dental facility control these items. However, all members of the dental care system must be aware ...
Nickel Alloy 22 is a fully austenitic, nickel-chromium-molybdenum-tungsten alloy with high corrosion resistance compared to other nickel-chromium alloys
Cobalt-chromium alloy (Co-Cr) particles in the nanometre size range are produced by wear at the articulating surfaces of metal-on-metal implants, and are associated with inflammation, bone loss and implant loosening. Additionally, metal implants undergo corrosion inside the human body releasing ions into the surrounding tissue. This led to the withdrawal from the market of the DePuy ASR™ metal-on-metal hip replacements in 2010. Ions released from Co-Cr particles derived from a resurfacing implant and their subsequent cellular up-take have been measured. Moreover, the ability of the metal debris and Cobalt (Co) ions to induce apoptosis was examined. For this purpose, U937 cells and Co pre-treated U937 cells were exposed to Co, metal debris and Co + debris for 24 and 48 h. To measure metal ion concentrations in culture medium and cell lysates Inductively Coupled Plasma Mass Spectrometry (ICP-MS) analysis was performed. Apoptosis was evaluated with Fluorescence-Activated Cell Sorting (FACS) and ...
This study compared the particulate and ion forms of a cobalt-chrome (Co-Cr) alloy on the differentiation/activation of preosteoblasts. Mouse preosteoblasts (MC3T3-E1) were cultured in an osteoblast-induction medium in the presence of particulate and ion forms of a Co-Cr alloy, followed by cell proliferation and cytotoxicity evaluations. The maturation and function of osteoblasts were assessed by alkaline phosphatase (ALP) assay and related gene expressions. Both particulate and ion forms of the metals significantly reduced the proliferation of MC3T3-E1 cells in a dose-dependent manner. Similarly, cells challenged with high concentrations of particles and ions exhibited a marked cytotoxic effect and diminished expression of ALP. Real-time (RT) polymerase chain reaction (PCR) data have suggested that cells with Co-Cr particles dramatically promoted over-expression of monocyte chemo-attractant protein-1 (MCP-1), tumor necrosis factor- (TNF-), and interleukin-6 (IL-6), whereas Co2+ ions treatment ...

To establish the methods of demonstrating early fixation of metal implants to bone, one side of a Cobalt-Chromium (CoCr) based alloy implant surface was seeded with rabbit marrow mesenchymal cells and the other side was left unseeded. The mesenchymal cells were further cultured in the presence of ascorbic acid, β-glycerophosphate and dexamethasone, resulting in the appearance of osteoblasts and bone matrix on the implant surface. Thus, we succeeded in generating tissue-engineered bone on one side of the CoCr implant. The CoCr implants were then implanted in rabbit bone defects. Three weeks after the implantation, evaluations of mechanical test, undecalcified histological section and electron microscope analysis were performed. Histological and electron microscope images of the tissue engineered surface exhibited abundant new bone formation. However, newly formed bone tissue was difficult to detect on the side without cell seeding. In the mechanical test, the mean values of pull-out forces were 77.15 N
Radial strength and low recoil are particularly important in bare-metal stents as Target Lesion Revascularization (TLR) rates are generally higher than drug-eluting stents. The Platinum Chromium Alloy combined with the REBEL customized architecture stent design allows for high radial and axial strength and the lowest stent recoil.

Colorization by anodizing is widely spread in the medical field, but is limited to titanium and aluminum components. In that sense, ALD technology is highly innovative as it can bring color to any material such as stainless steel, nitinol, and cobalt-chromium alloys. Colorization of medical instruments and devices enables clear and reliable identification to avoid mistakes during the operating steps. This has the huge advantage of reducing the stress for clinicians and improving the safety for patients. From a commercial point of view, in our fast paced environment, colorization by ALD NanoDeCo® coatings is a powerful marketing tool to distinguish products from competitors in the same field or to address specific markets. ...
Gertrude Emma Barrett born 1868 married Walter Costar on 23rd December 1888.. The 1891 census shows Walter age 24 and a Game-keeper and Gertrude with 2 children, Lizzie age 1 and Christopher age 8 months, living at Denmans Farm, Chawley, Cumnor, Berkshire.. The 1901 census finds Gertrude, now 32, living with her parents in Tubney. So, where is Walter? He is at 5 Station Road, Stratfield Mortimer, and is a coachman and hotel groom. Children: Lizzie age 11 Christopher age 10 Gertrude age 9 Walter Henry age 6 Frederick age 5 Annie age 3 Sydney age 1. Also there is Ellen, sister-in-law age 22 and described as housemaid.. Why is Gertrude with parents and Ellen with Walter and children? A thought for investigation, which surrounds a letter from one Nellie Costar to great grandfather Harrys wife Annie (Mary Anne Chandler). because the author of the letter is one Nellie Costar, I had assumed initially that it was written by Gertrude as her married name was Costar. However, Gertrudes middle name was ...
The aim of this investigation was to describe a new adaptation of the ST2R technique as reported by Clement et al.10 for thoracic hypokyphotic AIS patients. We focused on whether the ST2R technique would improve the TK apex location and outcomes relative to a case-matched cohort treated with RR.. However, one limitation of our study is the discrepancy of rods used in the RR and ST2R maneuvers, i.e., the 5.5-mm titanium versus the 6.0-mm cobalt-chrome alloy rods, respectively. This discrepancy is primarily due to the retrospective nature of the study and the consequential change in materials used over time in our practice. As such, outcome differences between the two techniques may be in part explained by the differences in the rods applied. Nevertheless, the roles of the rods in the RR and ST2R techniques are inherently different. RR uses a single rod to support a rotational correction of the spine at the concavity side, while a second rod is placed after the correction to provide support to ...

Objective: The composition of the salivary interface (pellicle) between dental restorations and oral mucosa may be critical to the biocompatibility of the restoration. The purpose of this study was to examine the molecular composition of the salivary pellicle on nickel-chromium alloy in vivo. Method and materials: The molecular components of nickel-chromium pellicle was examined with sodium dodecyl sulfate polyacrylamide gel electrophoresis and Western blot analyses. Results: Only limited numbers of salivary proteins were found to participate in the formation of nickel-chromium pellicle in vivo. Salivary amylase and secretory immunoglobulin A were among the proteins identified in the pellicle. Conclusion: In vivo, nickel-chromium pellicle consists of selectively adsorbed salivary proteins. Because both salivary amylase and secretory immunoglobulin A are antimicrobial proteins, it is possible that they play a role in modulating the microbial flora on the nickel-chromium prosthesis ...

Everolimus-eluting stents (EES) represent the next generation of drug-eluting stents (DES). Important design modifications include thin strut stent backbones, less inflammatory and more biocompatible polymers, and lower drug dosing. The cobalt chromium EES fluoropolymer XIENCE V stent has been the most extensively studied of such stents. In animal models, this stent demonstrated minimal vessel inflammation, a biologically active endothelium with strut coverage similar to a bare metal stent, and inhibition of intimal hyperplasia comparable to that seen with sirolimus-eluting stents. The SPIRIT family of clinical trials demonstrated low rates of late loss, and clinical restenosis, as well as low rates of very late stent thrombosis. These excellent clinical outcomes addressed limitations of the 1st generation DES, and substantiated widespread clinical use of the EES platform.
Implantable materials or biomaterials are utilized to repair, assist or replace living tissue or organs that are functioning below an acceptable level. A wide range of metals and their alloys, polymers, ceramics and composites are used in surgically implanted medical devices and prostheses and dental materials. These are important materials that provide the best dental implantations for patients. Most implanted devices are constructed of more than one kind of materials. Since the early 1900s, metal alloys have been developed for these applications to provide improved physical and chemical properties, such as strength, durability and corrosion resistance.. Major classes of metals used in medical devices and dental materials include stainless steels, cobalt-chromium alloys and titanium (as alloys and unalloyed). In addition, dental casting alloys are based on precious metals (gold, platinum, palladium or silver), nickel and copper and may in some cases contain smaller amounts of many other ...
Many of the metallic implants used in orthopaedics are made of stainless steel or cobalt-chromium alloys which contain 18-30% chromium. Hexavalent chromium (Cr VI) has been shown to be the predominant form of chromium released following in vivo and in vitro corrosion of these metal implants (Merritt and Brown, 1995 K. Merritt and S.A. Brown, J. Biomed. Mater. Res. 29 (1995), pp. 627-633. Full Text via CrossRef , View Record in Scopus , Cited By in Scopus (67)Merritt and Brown, 1995). Blood chromium levels may be elevated between 50 and 250 times in patients with metal hip implants (Lhotka et al., 2003). At physiological pH, Cr (VI) exists predominantly as the chromate anion and as such can enter cells via non-specific anion channels. The anionic Cr (VI) diffuses readily through the red blood cell (RBC) membrane and is bound by the haemoglobin probably after its rapid reduction to the cationic trivalent state within the RBC (Gray and Sterling, 1950). The aims of this study were to investigate the ...
Definition : Hook prostheses operated by myoelectric power and designed for partial functional replacement of a missing hand. These prostheses are typically external devices made of metal (e.g., cobalt-chromium alloys), hard plastics (e.g., polyethylene), carbon fibers, or a combination of materials; they may include totally or partially implanted components (e.g., sensors, electrodes). The prostheses are usually fixed with a socket to the wrist and require some degree of customization. Myoelectric controlled hand prostheses typically incorporate small electrical motors and electrodes within the socket to pick up electrical signals that trigger hook operation as the muscles in the residual limb contract. They may be used alone as a replacement for a missing hand or as the terminal component of a below-the-elbow, above-the-elbow, or total upper limb prosthesis in patients who have congenital abnormalities or who suffered amputations due to illness (e.g., diabetes) or traumatic accidents.. Entry ...
For successful wetting, the base metal must be at least partially soluble in at least one component of the brazing alloy. The molten alloy therefore tends to attack the base metal and dissolve it, slightly changing its composition in the process. The composition change is reflected in the change of the alloys melting point and the corresponding change of fluidity. For example, some alloys dissolve both silver and copper; dissolved silver lowers their melting point and increases fluidity, copper has the opposite effect. The melting point change can be exploited. As the remelt temperature can be increased by enriching the alloy with dissolved base metal, step brazing using the same braze can be possible. Alloys that do not significantly attack the base metals are more suitable for brazing thin sections. Nonhomogenous microstructure of the braze may cause non-uniform melting and localized erosions of the base metal. Wetting of base metals can be improved by adding a suitable metal to the alloy. ...
