متن کاملClinical Evaluation of Porcelain Fused to Metal Inlay-Retained Bridges
Introduction: Inlay retained bridges represent a conservative approach to restore single missing posterior tooth. Objective: To evaluate the clinical performance and survival rate of inlay retained fixed partial dentures. Materials and methods: A total of 12 patients were included in this clinical study. The patient selection, preparation technique as well as restoration fabrication followed cu...
متن کاملComparison of bond strength of a pressed ceramic fused to metal versus feldspathic porcelain fused to metal.
PURPOSE To compare the debonding/crack initiation strength (D/CIS) of a low-fusing pressable leucite-based glass ceramic (PC) fused to metal to a feldspathic porcelain (FP) fused to metal. MATERIALS & METHODS As per ISO 9693:1999, 40 rectangular metal specimens (25.0 mm x 0.5 mm x 3.0 mm) were prepared. Twenty of the specimens were cast in a base metal nickel-chromium alloy (BA), and 20 were ...
متن کاملEvaluating the effect of a sloping shoulder and a shoulder bevel on the marginal integrity of porcelain-fused-to-metal (PFM) veneer crowns.
AIM A porcelain-fused-to-metal (PFM) veneer crown restoration is considered successful when biological, mechanical, and esthetical concerns are satisfied. Restorations with poor marginal integrity may contribute to the cause of severe caries and periodontal defects. The most important factor in achieving successful marginal integrity is preparation design. Although a sloping shoulder preparatio...
متن کاملFracture Toughness of Veneering Ceramics for Fused to Metal (PFM) and Zirconia Dental Restorative Materials
Veneering ceramics designed to be used with modern zirconia framework restorations have been reported to fracture occasionally in vivo. The fracture toughness of such veneering ceramics was measured and compared to that of conventional feldspathic porcelain veneering ceramics for metal framework restorations. The fracture toughness of the leucite free veneer was measured to be 0.73 MPa m ± 0.02...
