Objective: To evaluate the influence of type cement on fracture resistance full-contour resin nanoceramic crowns cemented over preparations with knife-edge margins. Methods: A right lower premolar typodont model was prepared a 1.5-mm axial reduction, 2.0-mm occlusal and vertical margin. An anatomical crown designed from digital scanning preparation using CAD/CAM software. Then, 20 were milled b...

Conventional bioactive ceramic implants possess high osteogenic ability but exhibit poor machinability and brittleness, which limit their wide applications. In this study, we report an elastomeric machinable nanoceramic-based hybrid membrane that is formed by nanohydroxyapatite-reinforced matrix (poly(dimethylsilicone)-bioactive glass-poly(caprolactone) (nHA-PBP)) using a modified sol-gel proce...

OBJECTIVES The aim of this study was to evaluate the effects of 3 commercially available mouth rinses on the color stability of 4 different resin-based composite restorative materials. METHODS Forty disc-shaped specimens (10x2 mm) were prepared from each of the following materials: A nanofill composite Filtek Supreme XT (3M/Espe, St. Paul, MN, USA); a packable low-shrinkage composite, AeliteL...

BACKGROUND The purpose of this study was to investigate the effects of staining solutions and surface finishing on the colour stability and translucency of hybrid ceramic (HC) and resin nanoceramic (RNC) materials. METHODS Twenty four groups consisting of 10 specimens (240 specimens in total) were created out of HC and RNC, including six groups to be stored in distilled water served as the co...
