Wear of opposing teeth by posterior composite resins--evaluation of newly developed wear test methods.
In the present study, enamel wear against indirect composite resins was evaluated using two newly designed wear test methods: a rotating sliding wear test and a buff wear test. For the composite resins investigated in this study, their surface morphologies were examined using a scanning probe microscope after buff-polishing. After the wear tests, enamel was worn down by hard fillers that protru...
متن کاملThe in vivo wear resistance of 12 composite resins.
PURPOSE The in vivo wear resistance of 12 composite resins were compared with an amalgam control using the Latin Square experimental design. Sixteen edentulous patients wearing specially designed complete dentures formed the experimental population. MATERIALS AND METHODS The Michigan Computer Graphics Measurement System was used to digitize the surface of the control and composite resin sampl...
متن کاملFissure sealant materials: Wear resistance of flowable composite resins
Background. Wear resistance of pit and fissure sealant materials can influence their retention. Wear characteristics of sealant materials may determine scheduling of check-up visits. The aim of this study was to compare wear resistance of two flowable composite resins with that of posterior composite resin materials. Methods. Thirty-five disk-shaped specimens were prepared in 5 groups, includin...
متن کاملOne-Year Clinical Comparison of Two Posterior Composite Resins
Introduction: The aim of this study was to compare a one-year clinical performance of two composites (Ariston PHC with Tetric) in class II cavity preparations. Materials & Methods: Ninety-six class I and II modified cavity preparations in identical patients were prepared. Metallic matrix was used for restoration of class II preparations. Ariston PHC and Tetric were used for restorations. The cl...
متن کاملCompressive creep of posterior and anterior composite resins in water.
The compressive creep and the recovery of commercially available composites, 2 kinds for posterior and 2 kinds for anterior use, in water were examined. In posterior composites, creep strain after 500h at a stress level of 8.3 kgf/mm2 was significantly small (within 1%). The results of the compressive creep test showed that posterior composites would be resistant to occlusal stress. Creep strai...
