Ceramic Restorations In Dentistry

Ceramic materials used in dental restorations.

Ceramic restorations in dentistry.

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. For certain dental prostheses such as three unit molars porcelain. Restorative dentistry is based on four basic principles. Several summaries for the composition of dental porcelain have been written.

Biocompatibility of materials reduced tissue damage longevity of restorations and esthetic considerations. They cover the composition of felspathic porcelain as a veneering porcelain. Metal ceramic and all ceramic restorations. 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.

This has led to a series of differing ceramic structures available for dentistry with some examples described below. These dental porcelains were developed with the goal of controlling the propagation of cracks formed during the laboratory phase or in the clinical setting. The biggest advantage of the ceramic restoration is its permanent aesthetic quality. Due to improvements in materials and the sustained demand for esthetic and metal free restorations the use of all ceramic restorations has become ubiquitous.

Since there is a solid connection between the masking ceramic and the metal almost no changes of color will occur in the ceramic construction.
