Framework Design of Metal-ceramic Restorations

Marginal fit of leucite-glass pressable ceramic restorations and ceramic-pressed-to-metal restorations.

STATEMENT OF PROBLEM Fabricating a feldspathic porcelain margin on a metal-ceramic restoration with a clinically acceptable marginal fit has proven to be a technique-sensitive procedure. Pressable ceramics are advocated to solve this problem. PURPOSE The purpose of this in vitro study was to compare the marginal adaptation of a pressable ceramic system when used with both all-ceramic and meta...

Stress Distribution in Premolars with MOD Cast Metal Restorations

Little information is available on the stress analysis of cast metallic inlays and onlays. Modern design and valuation in order to obtain an adequate framework strength involves numerical simulations. The aim of the paper was to evaluate, the effect of MOD cavity design for cast metal inlays and onlays on stress distribution in teeth structures and restorations. The study was performed on an up...

Base metal alloys used for dental restorations and implants.

One of the primary reasons for the development of base metal alloys for dental applications has been the escalating cost of gold throughout the 20th century. In addition to providing lower cost alternatives, these nonprecious alloys were also found to provide better mechanical properties and aesthetics for some oral applications. Additionally, certain base metal alloy systems are preferred beca...

Fracture reasons in ceramic-fused-to-metal restorations.

Ceramic-fused-to-metal restorations are widely used in dentistry with a high degree of general success. Fracture of the ceramic veneers as a result of oral function or trauma is not an uncommon problem in clinical practice. Although fractures of such restorations do not necessarily mean the failure of the restoration, the renewal process is both costly and time consuming and therefore remains a...
