Ceramic Restorations In Dentistry

For certain dental prostheses such as three unit molars porcelain.

Ceramic restorations in dentistry.

Metal ceramic and all ceramic restorations. These dental porcelains were developed with the goal of controlling the propagation of cracks formed during the laboratory phase or in the clinical setting. Dental porcelain also known as dental ceramic is a dental material used by dental technicians to create biocompatible lifelike dental restorations such as crowns bridges and veneers evidence suggests they are an effective material as they are biocompatible aesthetic insoluble and have a hardness of 7 on the mohs scale. The biggest advantage of the ceramic restoration is its permanent aesthetic quality.

Several summaries for the composition of dental porcelain have been written. This has led to a series of differing ceramic structures available for dentistry with some examples described below. 1 although there is a plethora of all ceramic systems many are becoming obsolete almost as quickly as they were introduced due to the distinct advantages of lithium disilicate and zirconia. Due to improvements in materials and the sustained demand for esthetic and metal free restorations the use of all ceramic restorations has become ubiquitous.

Biocompatibility of materials reduced tissue damage longevity of restorations and esthetic considerations. Current materials for all ceramic restorations are reinforced with the addition of a variety of crystalline phases to the restorative mass such as leucite alumina and zirconia. Restorative dentistry is based on four basic principles. Since there is a solid connection between the masking ceramic and the metal almost no changes of color will occur in the ceramic construction.
