Ceramics applied to laminate manufacturing: literature review

Abstract

This paper aimed to discuss the types of ceramics indicated for making laminates and their aesthetic and mechanical implications, highlighting the composition of benefits and clinical indications. A narrative literature review was performed using the keywords in the search fields with the Boolean operators and and or to increase the sensitivity and specificity of the search in the Virtual Health Library. Works whose main theme was related to the objectives of this research were included search and, excluding duplicate texts or files unavailable for download. Ceramics have been used in dentistry since the 18th century in order to reproduce artificial teeth. The consulted literature presented excellent characteristics for these materials, such as: color stability, low plaque accumulation, biocompatibility, low thermal conduction, aesthetics and abrasion resistance. Currently, there are several systems for making laminates, with feldspathic ceramics being used more, as they have color stability, low conductivity and wear resistance; lithium disilicate has excellent aesthetics and translucency, and zirconia ceramic has greater resistance to flexion and fracture. In view of the foregoing, it became evident the need for knowledge of these materials, as well as the protocols for preparing the dental surface to then achieve clinical success with longevity, aesthetics and correct prosthetic rehabilitation.
