Abstract The present study was a prospective, controlled, randomized, clinical short-term trial aiming to evaluate the performance of adhesively luted, lithium disilicate and feldspathic glass-ceramics onlays over period up 2 years. A total 11 patients (7 female, 4 male; age range: 18-60 years, mean age: 39 years) were selected for this study. Each patient received maximum two restorations per ...

STATEMENT OF PROBLEM Computer-aided design and computer-aided manufacturing (CAD/CAM) generated restorations are gaining popularity. However, limited clinical evidence is available for single-unit posterior CAD/CAM restorations fabricated with established and newer crown materials. PURPOSE The purpose of this clinical study was to assess the restoration quality of and gingival response to CAD...

objectives: this study aimed to evaluate the effect of different ceramic surface treatments after machining grinding on the biaxial flexural strength (bfs) of machinable dental ceramics with different crystalline phases. materials and methods: disk-shape specimens (10mm in diameter and 1.3mm in thickness) of machinable ceramic cores (two silica-based and one zirconia-based ceramics) were prepar...

QDT 2013 Over the last decade, laboratory procedures have changed dramatically due to the introduction of computer-aided design/computerassisted manufacture (CAD/CAM) technology. This evo lu tion began with the use of zirconia as a base material for dental restorations. Recently, the use of CAD/CAM-fabricated full-contour zirconia (FCZ) crowns for posterior teeth has become a popular restoratio...
