Effect of Full Coverage, Endocrowns, Onlays, Inlays Restorations on Fracture Resistance of Endodontically Treated Molars

چکیده
Onlay is an extra-coronal restoration usually involving same area as inlay restoration and portion of outer cuspal slope, it is indicated in cases of steep cuspal inclines as wedging force tends to direct forces not parallel to the long axis of tooth [3]. The versatile inlay and onlay restorations require meticulous care in preparation, but when properly designed are extremely useful as durable restorations, able to withstand occlusal forces and more compatible with soft tissues as can be seen in gingival and subgingival margins [3].

Effect of different onlay systems on fracture resistance and failure pattern of endodontically treated mandibular molars restored with and without glass fiber posts.
PURPOSE To investigate the relationship between post and core build-up materials on the fracture resistance of endodontically treated teeth restored with different onlay restorations. METHODS 60 mandibular molars were endodontically treated and divided into three experimental groups that received one of the following onlay restorations: gold onlays, glass ceramic onlays (Empress I), or resin ...
متن کاملInfluence of endodontic treatment, post insertion, and ceramic restoration on the fracture resistance of maxillary premolars.
AIM To investigate the effects of endodontic treatment, post placement and ceramic restoration type on the fracture resistance of premolars. METHODOLOGY One hundred and twenty teeth maxillary premolars were allocated to four groups (A-D; n = 30). In group A, mesio-occlusal-distal-inlays with a buccal and palatal wall of 2 mm (MOD), in group B partial onlays with palatal cusp coverage and in g...
متن کاملRestoration of Endodontically Treated Molars Using All Ceramic Endocrowns
Clinical success of endodontically treated posterior teeth is determined by the postendodontic restoration. Several options have been proposed to restore endodontically treated teeth. Endocrowns represent a conservative and esthetic restorative alternative to full coverage crowns. The preparation consists of a circular equigingival butt-joint margin and central retention cavity into the entire ...
متن کاملConsiderations for Altering Preparation Designs of Porcelain Inlay/Onlay Restorations for Nonvital Teeth.
PURPOSE The aim of this study was to compare all ceramic inlay/onlay survival rates in vital and nonvital teeth having the same cavity design. Filling the pulp chamber with ceramic materials or not was also discussed. MATERIALS AND METHODS Ceramic class II inlays/onlays were made on 11 premolars and 30 molars: 14 vital, 27 endodontically treated. The same tooth preparation design was performe...

INTRODUCTION This in vitro study evaluated the influence of composite thickness (with or without fiber reinforcement) on fracture resistance of direct restorations in endodontically treated teeth. METHODS AND MATERIALS Fifty-six intact human premolars were chosen and randomly divided into four groups (n=14). After preparation of a mesio-occluso-distal (MOD) cavities and cusp reduction, the te...
