Metal-free alternative to PFM restoration exhibits strength and esthetics
نویسنده
چکیده
More than forty years after their development, porcelain-fused-to-metal (PFM) restorations remain the clinical standard to which other esthetic dental materials are measured. One of the drawbacks of PFM restorations is the difficulty with making them appear lifelike when viewed adjacent to natural teeth. All-ceramic restorations have become a welcome addition to the restorative armamentarium as their lack of a metal substructure allowed them to blend well with surrounding natural dentition. Initially used as a veneering material, all-ceramic materials were pressed into service as crowns as well. The natural extension was to use these materials to replace missing teeth as well.

Background and Aim: Replacing fractured ceramometal restorations may be the best treatment option, but it is costly. Many different bonding systems are currently available to repair the fractured ceramometal restorations. This study compared the shear bond strength of composite to a base metal alloy using 4 bonding systems.Materials and Methods: In this experimental in vitro study, fifty discs,...

A female presented to the office with a chief complaint concerning the esthetics of the porcelain-fused-to-metal (PFM) crowns on her maxillary lateral incisors. The objective was to use contemporary materials and techniques to have them blend better with her natural dentition. The PFM crowns had been completed at different times during her life. She said they did not match each other or her adj...

Although an all-ceramic restoration is increasingly in use in dentistry, a conventional metal ceramic restoration is still considered to be a gold standard. However, with increasing demand in esthetics and advances in ceramic technology, future of metal ceramic restoration has been less certain, necessitating additional qualities in terms of superior esthetics and easy fabrication. A ceramic-pr...
متن کاملReconstruction of anterior teeth using an aesthetic post-and-core and all-ceramic material.
Ceramic post-and-core systems offer biocompatibility, aesthetics, reinforcement of the remnant root, and prosthesis retention. Aesthetic posts-and-cores contribute to the optical properties of the overlying restorations when metal-free crowns are used. This article illustrates the use of these materials to provide strength and aesthetics during the restoration of endodontically treated teeth. T...

Significant progress has been achieved in ceramics since the late 1990s1-4). In particular, new technological innovations such as heat-pressed5,6), injection-molded7), slip-cast8), and glass-infiltrated ceramics9-11) have widened the use of ceramics in prosthetic and operative dentistry. However, properties such as brittleness limit their use in applications such as fixed partial dentures. Sinc...
