Resumo

O desenho de uma estrutura protética num computador seguido da sua confecção por uma máquina de fresagem é designado comumente por CAD-CAM. Essa tecnologia tem trazido uma evolução muito grande na Odontologia nos últimos 20 anos com o objetivo principal de otimizar a produção de estruturas protéticas. A evolução dos sistemas CAD-CAM tem sido acompanhada também pela evolução dos materiais, sobretudo da zircônia, a cerâmica mais resistente disponível nessa área. Entre os sistemas CAD-CAM para a Odontologia, este trabalho realça o Cerec®, o Procera®, o Lava® e especialmente o Everest®, sistema da Kavo® existente na Faculdade de Medicina Dentária da Universidade do Porto, Portugal.

Palavras-chave

Prótese parcial fixa, planejamento de prótese dentária, tecnologia odontológica, materiais dentários, zircônio

Abstract

The virtual design of a structure, followed by its machining in a milling unit is normally called as CAD-CAM. This technology has evolved greatly in Dentistry in the last 20 years, with the main purpose of optimizing the production of prosthetic structures. Together with the evolution of this systems we can observe the changes in dental materials, specially zirconia, the most resistant ceramic available in Dentistry. Within this CAD-CAM systems this manuscript will focus the Cerec®, the Procera®, the Lava®, and specially the Everest®, from Kavo® corporation, which exists in the Dental Faculty of Porto University, Portugal.

Keywords
