statement of problem: recent clinical results for zirconia all-ceramic restorations have revealed that the fracture rate 6-15% of the zirconia framework is so low and the core of zirconia has high stability. however, chipping-off fractures of porcelain are the most common reason for failures of zirconia in the fixed partial dentures. objectives: the purpose of this study was to compare the shea...

In this article, we review the recent history of the development of dental CAD/CAM systems for the fabrication of crowns and fixed partial dentures (FPDs), based on our 20 years of experience in this field. The current status of commercial dental CAD/CAM systems developed around the world is evaluated, with particular focus on the field of ceramic crowns and FPDs. Finally, we discuss the future...

A detailed review on Guggulu, covering its botanical, Chemical Pharmacological and Ayurvedic aspects, is presented here.

PURPOSE This retrospective clinical study evaluated the long-term outcomes of cantilever fixed partial dentures (CFPDs) and the factors influencing their survival probability. MATERIALS AND METHODS The study is based on a convenience sample of 57 patients who received 71 CFPDs on a total of 176 vital abutment teeth. The mean survival time of the CFPDs was calculated using a Kaplan-Meier estim...

PURPOSE This study evaluated the vertical misfit of implant-supported frameworks made using different techniques to obtain passive fit. MATERIALS AND METHODS Thirty three-unit fixed partial dentures were fabricated in cobalt-chromium alloy (n = 10) using three fabrication methods: one-piece casting, framework cemented on prepared abutments, and laser welding. The vertical misfit between the f...

In the described technique, a vinyl polysiloxane material is used as a matrix for the indirect fabrication of multiple custom-cast posts and cores. The matrix technique enables the clinician to fabricate multiple posts and cores in a short period of time. The form, harmony, and common axis of preparation for all cores are well controlled before the definitive crown/fixed partial denture restora...

In the diversified literature on occlusion and its role for functional patterns of the masticatory system, two conflicting concepts stand out: (1) canine protection as described by D’Amico and others is said to favor a vertical chewing pattern and to prevent wear of teeth, as in lateral occlusion where the canine guides the mandibular movement directly through contact or indirectly through peri...
