A study on the fracture strength of collarless metal-ceramic fixed partial dentures
PURPOSE The objective of this study was to evaluate fracture strength of collarless metal-ceramic FPDs according to their metal coping designs. MATERIALS AND METHODS Four different facial margin design groups were investigated. Group A was a coping with a thin facial metal collar, group B was a collarless coping with its facial metal to the shoulder, group C was a collarless coping with its f...
متن کاملFiber-reinforced Fixed Partial Dentures: a Preliminary Retrospective Clinical Study
The aim of this study was to evaluate the clinical performance (retention rate) of fiber-reinforced composite fixed partial dentures (FPDs). Polyethylene fiber (Ribbond) was used combined with restorative composite during FPDs fabrication. FPDs were placed in thirteen patients in a private clinic. Nineteen FPDs were evaluated. The prosthetic space was filled with only one pontic using extracted...
متن کاملFatigue Fracture Strength of Implant-Supported Full Contour Zirconia and Metal Ceramic Fixed Partial Dentures
Objectives Zirconia restorations have been suggested as a more durable and more appealing alternative to metal restorations. However, their mechanical properties may be negatively affected by fatigue due to superficial stresses or low temperature degradation. This study aimed to assess the fatigue fracture strength of three-unit implant-supported full contour zirconia and pre-sintered cobalt-ch...
متن کاملPost Cementation Sensitivity in Vital Abutments of Metal-ceramic Fixed Partial Dentures
This randomized clinical trial was carried out to compare post cementation sensitivity in vital abutments of metal-ceramic fixed partial dentures using glass ionomer luting cement and resin based luting cement. It analyzed the results of 182 patients whose records were completed during study duration of 09 months at Department of Prosthodontics, AFID, Rawalpindi. Cold sensitivity tests were use...
متن کاملeffect of taper on stress distribution of all ceramic fixed partial dentures: a 3d-fea study
statement of problem: mechanical failure of ceramic materials is controlled by brittle fracture, mostly occurred in tension. in 3-unit all-ceramic fpds the connector area is considered to be at fracture risk because of tensile stress concentrations. purpose: the aim of this fe analysis was to evaluate the effect of taper on stress distribution in all-ceramic fpds. materials and methods: in this...
