Fracture strength of endodontically treated premolars restored with different post systems and metal-ceramic or monolithic zirconia crowns
نویسندگان
چکیده
The purpose of this study was to investigate the fracture strength endodontically treated human maxillary premolars (ETP) restored with posts and metal ceramic (MC) or monolithic zirconia (MZ) crowns. Sixty ETP were randomly divided into 3 groups. Teeth in control group (C) received a resin filling. MC prefabricated posts, composite cores crowns while MZ glass-fiber Half specimens loaded at 135° angle half under axial loading until fracture. modes repairable irreparable using optical microscopy. Mean significantly higher for than only loading. distribution failures presented no significant differences. Crown placement improved irrespectively post crown type.
