Ceramic Restorations In Dentistry

Several summaries for the composition of dental porcelain have been written.

Ceramic restorations in dentistry.

The biggest advantage of the ceramic restoration is its permanent aesthetic quality. These dental porcelains were developed with the goal of controlling the propagation of cracks formed during the laboratory phase or in the clinical setting. Since there is a solid connection between the masking ceramic and the metal almost no changes of color will occur in the ceramic construction. Biocompatibility of materials reduced tissue damage longevity of restorations and esthetic considerations.

They cover the composition of felspathic porcelain as a veneering porcelain. 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. Metal ceramic and all ceramic restorations. The wide range of clinical applications for.

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. The steady advance in the development of materials coupled with improved understanding of ceramic bonding reinforcement and light transmission has given further emphasis to the esthetic aspects of restoration. This has led to a series of differing ceramic structures available for dentistry with some examples described below. Due to improvements in materials and the sustained demand for esthetic and metal free restorations the use of all ceramic restorations has become ubiquitous.
