Post-fatigue fracture resistance of metal core crowns: press-on metal ceramic versus a conventional veneering system
BACKGROUND The aim of this in vitro study was to compare the mechanical failure behavior and to analyze fracture characteristics of metal ceramic crowns with two veneering systems - press-on metal (PoM) ceramic versus a conventional veneering system - subjected to static compressive loading. MATERIAL AND METHODS Forty-six crowns were constructed and divided into two groups according to porcel...
متن کاملThe influence of veneering porcelain thickness of all-ceramic and metal ceramic crowns on failure resistance after cyclic loading.
STATEMENT OF PROBLEM In some clinical situations, the length of either a prepared tooth or an implant abutment is shorter than ideal, and the thickness of a porcelain crown must be increased. Thickness of the coping and the veneering porcelain should be considered to prevent mechanical failure of the crown. PURPOSE The purpose of this study was to investigate the influence of veneering porcel...
متن کاملIn Vitro Evaluation of Fracture Resistance of Zirconia Restorations Veneered by Two Different Systems: Rapid Layer Technique and Zir/CAD/CAM
Background: This study aimed to assess the fracture resistance of zirconia restorations fabricated with rapid layer (RL group) technique and zirconia computer-aided design/computer-aided manufacturing (zir/CAD/CAM) system (ZC group). Methods:This study evaluated 30 all-ceramic crowns in two groups of 15. After fabricating the metal dies and scanning them ...
متن کامل[Fiber post versus metal screw post for repair of residual crowns and roots: a systematic review].
PURPOSE To evaluate the restorative effectiveness of fiber post versus metal screw post through systematical review. METHODS Randomized controlled trials (RCTs) data from the establishment of the database up to June 2013 were searched from MEDLINE (Ovid), PubMed, The Cochrane Library, Embase, Wanfang Data, VIP, CNKI and CBM using the designed strategy. After data extraction and quality review...
متن کاملA two-year clinical study of metal-ceramic and metal-polymer crowns.
The purpose of this study was to compare full metal crowns with two different types of veneering material - ceramics and polymer after a two-year period in a function. The aim was to evaluate the changes of occlusal relief, marginal adaptation, break of material, changes of shape and color and gingival status. One hundred and two crowns were examined in 34 patients immediately after cementation...
