Adhesion of adhesive resin to dental precious metal alloys. Part I. New precious metal alloys with base metals for resin bonding. (1/860)

New dental precious metal alloys for resin bonding without alloy surface modification were developed by adding base metals (In, Zn, or Sn). Before this, binary alloys of Au, Ag, Cu, or Pd containing In, Zn, or Sn were studied for water durability and bonding strength with 4-META resin. The adhesion ability of the binary alloys was improved by adding In equivalent to 15% of Au content, Zn equivalent to 20% of Ag content, and In, Zn, or Sn equivalent to 5% of Cu content. There was no addition effect of the base metals on Pd, however 15% of In addition improved adhesion with Pd-based alloys containing equi-atomic % of Cu and Pd. The alloy surfaces were analyzed by XPS and showed that oxides such as In2O3, ZnO, or SnO play an important role in improving the adhesive ability of the alloys.  (+info)

It is considered that the poor adhesive ability of the pure gold and alloys containing only small amounts of In was due to the chemisorbed H2O molecules and insufficient indium oxide on the alloy surface. It was established that excellent adhesion requires an oxide with chemical affinity for 4-META to cover at least 50% of the alloy surface.  (+info)

Super pulse CO2 laser for bracket bonding and debonding. (3/860)

A super pulse and a normal pulse CO2 laser were used to carry out enamel etching and bracket debonding in vitro and in vivo. The shear bond strength of the orthodontic brackets attached to laser-etched and conventional chemically-etched extracted premolars was measured. The pulp cavity temperature was also measured using the same laser irradiation conditions as the shear test. Both super pulse and normal pulse CO2 laser etching resulted in a lower shear bond strength (super pulse: 6.9 +/- 3.4 kg, normal pulse: 9.7 +/- 5.2 kg) than that of chemical etching (15.3 +/- 2.8 kg). Furthermore, the super pulse CO2 laser was able to create debonding at 2 watts within a period of less than 4 seconds (2.9 +/- 0.9 seconds). The super pulse, when irradiating the ceramic brackets from above, during debonding showed a 1.4 degrees C temperature increase in the dental pulp at 2 watts and an increase of 2.1 degrees C at 3 watts. While etching, directly irradiating the enamel surface at 3 watts, the dental pulp showed a temperature increase of 3.5 degrees C. These temperature increases were within the physiologically acceptable limits of the pulp. These results indicate that, in orthodontic treatments, super pulse CO2 laser debonding is more useful than laser etching.  (+info)

An ex vivo investigation into the bond strength of orthodontic brackets and adhesive systems. (4/860)

The aim of this study was to compare the shear bond strength of Adhesive Precoated Brackets (APC) with that of two types of uncoated bracket bases, Straight-Wire and Dyna-Lock. Two types of orthodontic adhesives were used, Transbond XT and Right-On. Three different curing times were evaluated with the APC brackets in order to find the best. Adhesive remnants on the enamel surface following debond were evaluated using the Adhesive Remnant Index (Artun and Bergland, 1984). Bond strengths ranged from 11.00 to 22.08 MPa. For both types of brackets Transbond produced a significant increase in bond strength compared to Right-On. The Dyna-Lock/Right-On combination produced the poorest results. APC brackets cured for 40 s had similar bond strengths to uncoated brackets fixed by means of Transbond. Overall, 79 per cent of specimens had less than half the tooth surface covered with adhesive following debond. Significantly more adhesive remained on tooth surfaces following debond of the Straight-Wire/Right-On group than any other bracket/adhesive combination. Bond strengths were higher with light-cured Transbond than with chemically-cured Right-On. When Transbond is used in association with APC brackets a 40-second cure time is recommended.  (+info)

The effects of sandblasting on the bond strength of molar attachments--an in vitro study. (5/860)

This study evaluated the effect of sandblasting foil mesh molar tube bases on the shear bond strength obtained when bonding to first molar teeth. Fifty-two recently extracted first molar teeth were etched with 35 per cent phosphoric acid gel for 30 seconds. Twenty-six sandblasted 'A' Company molar tube attachments and 26 non-sandblasted attachments were then bonded to the teeth using Phase II orthodontic bonding resin. After storage in water for 24 hours at 37 degrees C, the specimens were debonded in a direction parallel to the buccal surface. Survival analysis using the Weibull function revealed that for a 90 per cent probability of survival, the predicted bond strengths for sandblasted and non-sandblasted bases were 1.76 and 1.66 MPa, respectively. For larger shear stresses, the probabilities of bond survival with sandblasted molar tubes were greater than with non-sandblasted molar tubes although the differences were small, which may be explained by the large proportion of bond failures which occurred at the resin to enamel interface in both groups. It was concluded that sandblasting foil mesh bases is likely to provide only a minimal improvement in clinical performance when bonding to molar teeth.  (+info)

A laboratory investigation to compare enamel preparation by sandblasting or acid etching prior to bracket bonding. (6/860)

A laboratory investigation to compare the mean shear debonding force and mode of bond failure of metallic brackets bonded to sandblasted and acid-etched enamel is described. The buccal surfaces of 30 extracted human premolars were sandblasted for 5 seconds with 50 mu alumina and the buccal surfaces of a further 30 human premolars were etched with 37 per cent phosphoric acid for 15 seconds. Following storage for 24 hours at 37 degrees C in distilled water, shear debonding force was measured using an Instron Universal Testing Machine with a cross-head speed of 10 mm/minute. Mean shear debonding force was significantly lower for brackets bonded to sandblasted enamel compared to acid etched enamel (P < 0.001). Weibull analysis showed that at a given stress the probability of failure was significantly greater for brackets bonded to sandblasted enamel. Brackets bonded to etched enamel showed a mixed mode of bond failure whereas following sandblasting, failure was adhesive at the enamel/composite interface (P < 0.01).  (+info)

Factors affecting the shear bond strength of orthodontic brackets to porcelain. (7/860)

The aim of this investigation was to establish a regime for orthodontic bonding to feldspathic porcelain, which ensures adequate bond strength (6-8 MPa) with minimal damage on debond and consisted of an ex vivo investigation measuring the effects of porcelain surface preparation and thermocycling on shear bond strength of orthodontic brackets. One-hundred-and-twenty feldspathic porcelain bonded crown surfaces were divided into 12 equally-sized groups to assess the effects of: (1) glaze removal, (2) application of hydrofluoric acid, phosphoric acid, or omission of acid treatment, and (3) silane priming upon the bond strength of premolar brackets bonded with Right-on (TM) composite resin adhesive. Specimens were subjected to thermocycling and then to shear debonding forces on an Instron machine. Removal of the porcelain glaze, or use of hydrofluoric acid, prior to bonding were found to be unnecessary to secure the target bond strength. Hydrofluoric acid application was associated with increased porcelain surface damage. Thermocycling caused a significant reduction in shear bond strength to porcelain (P < 0*001). The best regime for orthodontic bonding to feldspathic porcelain was to apply phosphoric acid for 60 seconds, and prime with silane prior to bonding. Usually the porcelain surfaces could be repolished. Refereed Paper  (+info)

Evaluation of the amount of residual monomer on UDMA-based resins by FTIR. (8/860)

The purpose of this study was to establish a method using FTIR to evaluate the polymerization characteristics of UDMA-based resins. Three kinds of experimental UDMA-based resins were prepared with various molar fractions. IR spectra of the cured film specimens were measured with FTIR before and after extracting residual monomer from each specimen by MeOH. From the IR spectra, the changes in the number of double bonds were measured, with the NH absorbance peak as an internal standard, and the amounts of residual monomers (RM) were calculated. The MeOH-immersed specimens were analyzed by HPLC. The RM measured by FTIR were compared with those measured by HPLC. The RM measured by HPLC were more than those by FTIR. Since these differences could be due to the difference in the area measured, this FTIR estimation method of residual monomers in cured resins using the NH absorbance peak as an internal standard could be an appropriate method when the resin monomer does not contain aromatic compounds.  (+info)

This study investigated the relationship between the irradiance transmitted through ceramic and the bond strength of a resin cement to dentin. After application of an adhesive system, elastomer molds with cylindrical orifices (1.2 mm in diameter) were placed onto bovine dentin surfaces and filled with a photoactivated luting agent (Enforce; Dentsply Caulk). Light-activation was performed through a 0.6-mm-thick ceramic disc using different intensities: 250, 400, 550, 700, or 850 MW/cm(2). Control specimens were irradiated without ceramic (1050 mW/cm(2)). The radiant exposure was kept at 30 J/cm(2). Light spectral distribution was analyzed with a spectrometer. Microshear test was conducted and modes of failure were classified under SEM. Bond strength data were analyzed with ANOVA and Student-Newman-Keuls test (alpha ,= 0.05), and failure scores with the Kruskal-Wallis test (alpha ,= 0.05). A linear regression model assessed the relationship between irradiance and bond strength. Groups lightcured ...
The purpose of this study was to evaluate the influence of surface treatments and thermocycling on the microtensile bond strength (μTBS) of self-adhesive resin cement to human enamel and dentin. Eighty human third molars were selected. The crowns of 40 teeth were transversally sectioned, exposing the mid-coronal dentin. The buccal surfaces of the other 40 teeth were grinded to obtain a 5 mm2 flat enamel area. Eighty resin blocks were produced and cemented to the dental surfaces with RelyX Unicem, then grouped according to the surface treatment (n = 10): UnicemC with no conditioning, UnicemP with 37% phosphoric acid/15 s, and UnicemPA with 37% phosphoric acid/15 s plus adhesive bonding (Single Bond 2). There were two control groups, one for enamel and the other for dentin: VR with 37% phosphoric acid/15 s plus adhesive bonding (Single Bond 2) plus Variolink II. The enamel-dentin resin cement blocks were sectioned to produce non-trimmed bar specimens, which were divided into two storage ...

This next generation of the original PANAVIA SA Cement offers stronger shear bond strengths; faster light-curing time; and room temperature storage. Its EASY CLEANUP reduces the risk of gingival trauma, making it deal for indirect procedures... PANAVIA SA Cement Plus has been developed for cementing indirect restorations made of metal, all-ceramic (zirconia), hybrid ceramics and composites. This self-adhesive resin cement does not require phosphoric acid treatment or any special primer or adhesive for bonding to tooth structure. Obtaining a strong, durable bond to zirconia can be challenging. PANAVIA SA Cement Plus, with its high concentration of the original MDP, bonds to zirconia chemically, as well as micromechanically. Bond strengths are virtually unaffected by the dryness or wetness of the tooth structure. It also contains a new Radical Amplifier, which increases the rate of polymerization, shortens the light-curing time, and increases the bond strength.. Features. ...
MATERIALS AND METHODS: Y-TZP zirconia specimens in three experimental groups were subjected to Y-TZP particle deposition via dipping into the milling residue suspension at different times prior to the sintering process. The dipping procedure was repeated twice for each specimen in group B, six times in group C, and ten times in group D. The specimens subjected to airborne-particle abrasion (110 μm Al2 O3, Rocatec Pre) acted as the control group (group A). All of the specimens were then bonded using adhesive resin cement (RelyX Ultimate). A μ-PO test was used to determine the bond strength values. One-way ANOVA at a 5% confidence level was performed for data analysis. Optical microscopy and scanning electron microscopy (SEM) were used to evaluate the failure modes and surface structure ...

The IPS d.SIGN 20g porcelain material features true-to-nature light scattering and high translucency while also effectively masking metal framework. Use in conjunction with the IPS d. SIGN Opaquer.
The combination of selective etching using a universal adhesive and placing bulk-fill composite facilitates restoring various tetth in the posterior region. This method allows virtually invisible restorations to be achieved that are indistinguishable from surrounding dentition. As TetricEvoFlow Bulk Fill changes its translucency during polymerization and obtains a dentin-like opacity, the natural translucency of teeth can be more easily mimicked and small stains are even masked. The restorations are also permanently stable and esthetic, yet completed in less chair time, which makes the practice more efficient and saves patients time and money. ...

The aim of this in vitro study was to compare the shear bond strength (SBS) and failure modes of a conventional resin-based composite with a recently developed amorphous calcium phosphate (ACP)-containing orthodontic composite system. Forty freshly extracted human maxillary premolar teeth were randomly divided into two equal groups. Conventional composite (group 1; Transbond-XT®; 3M Unitek) and ACP-containing orthodontic composite (group 2; Aegis-Ortho®; Harry J. Bosworth Co.) were used for bonding ceramic orthodontic brackets. The SBS of these brackets were measured and recorded in megapascals (MPa). Adhesive remnant index (ARI) scores were determined after bracket failure. Data were analysed with a Students t-test for two independent variables and Pearsons chi-square tests.. Statistical analysis showed that the bond strength of group 1 (mean: 36.7 ± 6.8 MPa) was significantly higher than group 2 (mean: 24.2 ± 5.4 MPa; P , 0.01). Although a greater percentage of the fractures were ...

Maybe weve come full circle. We are now fully in dentin, and have the choice of what cement and bonding agents to use. At this point you may ask why not just use a traditional self adhesive resin cement or a glass ionomer. The reasons why not, are at least two. The self adhesive resin cements are all dual cure and notoriously suffer from yellowing. Glass ionomers, even the resin modified variety, must contain water and therefore are more soluble than resin cements. Remember we are after a long-term aesthetic result. Yellowing and staining a few years down the road is not acceptable today.The second reason is that veneers are more prone to coming off as opposed to a crown (less retention, particularly lateral forces), recall those of you old enough - what used to happen to veneers in the early 1980s? So for these reasons when it comes to dentin only, go ahead and use a dentin bonding agent. I have fought this battle before with the self adhesive resin cements, I know many of you are in love ...
Methods: Zirconia (IPS e.max ZirCAD, Ivoclar Vivadent) and resin composite blocks were obtained and randomly divided into four groups according to one of the following surface conditioning methods: C: No surface treatment (Control); AS: Air abrasion (50 µm Al2O3) at low pressure (0.2 MPa) plus silane (Monobond Plus, Ivoclar Vivadent); MC: Methylene chloride for 60 min; CE: Chemical etching solution at 100°C for 60 min. Surface roughness (Ra) measurements were performed on the control and conditioned zirconia specimens using a profilometer. Each conditioned zirconia block was bonded to its corresponding resin composite block using self-adhesive resin cement (RelyX Unicem Aplicap, 3M ESPE) under a load of 300 g. Half of the groups were tested without aging; the other half were tested after x6000 thermocycling. Sticks were obtained from bonded specimens and subjected to microtensile bond strength (MTBS) testing in a universal testing machine (0.5 mm/min). Failure types were classified after ...

This study evaluates and compares the effects of enamel prophylaxis using either oil-free pumice or oil-containing prophylaxis paste on the incidence of bracket failure in orthodontic patients.. Forty-six orthodontic patients participated in this prospective clinical trial. A cross-mouth method was used in each patient, in which two diagonal quadrants (i.e. upper right and lower left or vice versa) were randomly assigned to the pumice group and the contralateral diagonal quadrants to the Prophy Paste (R) group. A total of 836 teeth were bonded using Transbond XT (3M Unitek) and monitored for an average of 23 months for bond failure. Chi-square analysis was used to compare the number of bracket failures between the groups.. Overall, 26 bond failures occurred by the end of the trial. Fifteen bracket failures were observed in the Prophy Paste group (3.6%) and 11 in the pumice group (2.6%). The failure rates were fairly evenly distributed between the upper and lower jaws. There were no statistically ...
Materials and Methods: Buccal enamel of 80 bovine teeth was submitted to finishing and polishing with metallographic paper to a refinement of #600, in order to obtain a 5-mm2 flat area.

Should a universal adhesive be used with a self- or dual-cured buildup or cement?. Although universal adhesives are typically on the higher end of the pH spectrum of self-etching adhesives, they are still relatively acidic (Figure 2). A common problem of any one-step self-etching adhesive is they will leave an acidic surface following application to tooth structure. This acidic surface will interfere with the amine-based chemical reaction used to cure self-cured or dual-cured resins.17 In other words, application of an acidic universal adhesive to tooth structure can prevent curing of a self-cured resin cement or buildup material placed on top of it. In some cases, this may cause debonding of a buildup, post or fixed restoration.. There are two methods to avoid this possible failure. The first is to use a dual-cure activator with the universal adhesive. This activator is typically sold with the universal adhesive and can be mixed in a 1:1 ratio with the adhesive. It contains arylsulfinate salts ...
Background: Several studies possess investigated the result from the activation mode of adhesive systems on bond strength of dietary fiber posts to root canal dentin. the known degree of significance. Results: The best bond power was acquired for AdheSE dual-cure (15.54 6.90 MPa) and the cheapest was obtained for Excite light-cure (10.07 7.45 MPa) in support of the bond power between both of these adhesives had factor (= 0.02). Relationship strength decreased through the coronal towards the apical in every organizations which was significant in Excite (group 1) and AdheSE (group 3) (< 0.001). In apical areas, bond power of dual-cure adhesives was considerably greater than light-cure adhesives (< 0.001).

Wipe the surface with wax and grease remover to get it clean enough so nothing interferes i.e. fingerprints. The self-etching primer is usually gray or olive drab gray but the color is just there to show you where youve put it on and it is very thin and one thin coat is enough. Putting more of the primer wont make it work better. You can apply it over paint or bondo but it is only effective on bare metal. You can apply your high build primer or body filler over the self-etching primer but be careful it is not a finished product by it self ...
