Uso da tecnologia CAD/CAM na Odontologia: do enceramento diagnóstico ao desenho digital integrado. A mudança de um paradigma

RESUMO

O objetivo deste trabalho foi descrever a técnica de DDI (desenho digital integral) em substituição ao ED (enceramento diagnóstico), mudando um paradigma na Odontologia. Com o uso do DDI, não é necessário realizar o enceramento diagnóstico para estabelecer a meta protética. Esta é obtida digitalmente em um ambiente 3D, com mais requinte de informações e maior precisão. O DDI é então materializado (prototipado) utilizando uma impressora 3D, dentro do ambiente do consultório. Atualmente, os recursos CAD/CAM de baixo custo estão disponíveis para uso odontológico, e os resultados obtidos com esta tecnologia justificam a incorporação do tratamento 3D. Desta forma, a técnica do enceramento dental estaria próxima do fim, sendo que, em um futuro próximo, dentistas/técnicos de prótese serão dental digital designers e todo o conhecimento se voltará para o domínio dos programas de informática, e não para aquisição de equipamentos complexos e de alto custo.

Palavras-chave – Projeto auxiliado por computador; Projeto usinado pelo computador; Tomografia computadorizada de feixe cônico; Impressão tridimensional.

ABSTRACT

The objective of this study was to describe the IDD technique (integrated digital design) to replace the DW (diagnostic waxing) as a paradigm shift in Dentistry. In this way, it is not necessary to perform the diagnostic waxing to establish the prosthetic outcomes. This is achieved in a 3D environment, with more information refinement and greater accuracy. The IDD is then materialized (prototyped) using a 3D printer within the dental office. Currently, the CAD/CAM resources are low-cost and available for dental use, with the obtained results justifying the incorporation of the 3D dental treatment. Thus, the diagnostic waxing would be close to an end; in the near future, clinicians/laboratory technicians will be dental digital designers and all knowledge will be managed to computer software domain and not to the acquisition of complex and expensive production equipment.

Key words – Computer-aided design; Computer-aided machining; Cone beam computerized tomography; 3D printing.
