Fracture resistance of crowns cemented on titanium and zirconia implant abutments: a comparison of monolithic versus manually veneered all-ceramic systems.

Abstract

PURPOSE To evaluate the fracture resistance of all-ceramic crowns cemented on titanium and zirconia implant abutments. MATERIAL AND METHODS Customized implant abutments for maxillary right central incisors made of titanium (Ti) and zirconia (Zr) (n=60, n=30 per group) were fabricated for an internal connection implant system. All-ceramic crowns were… (More)
