“…15 However, several studies showed that heat-cured PMMA denture-base resin was better for use with MMA-based repair resin compared with non-MMA-based resin. [16][17] While Gregory and others 18 found that the repairs of resin composite with identical matrix chemistry did not produce bond strengths greater than those with a 511 B In the current study, both self-cured (Alike) and heat-cured (Namilon) PMMA resins showed higher bond strengths with methacrylate-based repair resin, regardless of whether the curing mode of the repair resin was self-cured or light-cured.…”

SUMMARYThis study evaluated the repair bond strengths of light-cured resins to provisional restoration materials with different chemical compositions and polymerization techniques. Fifty discs (10 mm in diameter and 1.5 mm thick) were fabricated for each provisional resin base material, including a self-cured methacrylate (Alike), selfcured bis-acrylate (Protemp 3 Garant), lightcured bis-acrylate (Revotek LC) and a heat-cured methacrylate (Namilon). All specimens were stored in distilled water at 37°C for seven days before undergoing repair with one of four lightcured resins, including AddOn, Revotek LC, Dyractflow and Unifast LC and a self-cured resin (Alike), according to the manufacturers' instructions, for a total of 200 specimens. After 24 hours of storage in 37°C water, the shear bond strengths were measured with a universal testing machine and fracture surfaces were examined under a stereomicroscope. Two-way ANOVA revealed that provisional resin-base material (p<0.001), repair material (p<0.001) and their interactions (p<0.001) significantly affected the repair strength. Tukey's multiple comparisons showed that the lowest bonding strengths were found in specimens of heat-cured methacrylate resin materials repaired with bis-acryl resins, with their failure modes primarily being of the adhe- Clinical RelevanceSpecific repair resins should be chosen for certain provisional materials, since optimal bond strength can be achieved only when the repair resin has similar chemical components to those of the resin matrix (either methacrylate or bis-acryl) for the provisional restoration.sive type. The highest bond strengths were recorded when the provisional resin-base materials and repairing resins had similar chemical components and the failure modes tended to be of the cohesive type.

“…Adhesives promote penetration of solvent systems and of monomers into the composite surface, depending on the degree of hydration and the chemical affinity of materials, and create a non-polymerized oxygen inhibition layer that could ultimately promote adhesion of new composites [32,33]. However, the study of Hagge et al [34] showed that the shear bond strength values of the flowable composite resin were significantly higher in surface treatment with sandblasting alone than with the combination of sandblasting and adhesive monomer. The results of the present study correspond well with those of the earlier studies in the composite resin.…”

This study evaluated the effect of surface treatments on the bond strength of repaired temporary resins. One-hundred flat-surfaced cylindrical specimens (Ø 7 mm 9 12 mm) of each temporary resin (2 bis-acryl resins and 2 polymethyl-methacrylates) were prepared. The specimens were randomly divided into 10 groups (n = 10), according to the types of surface treatments: untreated, adhesive treated, silanated, silane ? adhesive treated, hydrofluoric acid etched, laser treated, sandblasted, sandblasting ? adhesive treated, sandblasting ? silanated, and tribochemical silica coating ? silanated. Each resin material of the same brand with cylindrical shape (Ø 3 mm 9 3 mm) was polymerized onto the resin surfaces, and specimens were stored for 24 h in distilled water. The shear bond strengths were measured and failure modes were examined. All data were analyzed with a one-way ANOVA and multiple comparison Scheffé post hoc test (a = 0.05). For bis-acryl resins, the highest shear bond strength was observed in sandblasted group and the lowest was observed in the control group. Results show that the repair bond strength was improved for bis-acryl resin by 23 % than that of the control group due to the increase in surface roughness by sandblasting. However, chemical treatment did not improve repair bond strength. The surface treatment of bis-acryl resins with sandblasting seems to be promising for the improvement of repair bond strength.

“…If a composite repair tends to fracture within the original composite (cohesive fracture), one can assume the selected protocol to be appropriate to bear the occlusal loads. The location of the repair failure within the repaired material itself, rather than at the adhesive surface, suggests a better bond 16) . Nevertheless, shear bond strength tests may cause cohesive fractures of the substrate.…”
