Abstract(s)
O uso do CAD/CAM na área da Medicina Dentária está altamente estabelecido em reabilitações unitárias, e parciais fixas, oferecendo uma alta precisão neste sentido. Não obstante, o uso do scanner intraoral e a tecnologia stereo-photogrammetry é cada vez mais usada na realização de impressões digitais em reabilitações totais sobre implantes. O sistema 3Shape® TRIOS é um scanner intraoral utilizado na medicina dentária para obter impressões digitais de superfície como são os tecidos moles e duros bucais. Por outro lado, o PIC Dental® permite a captação da posição dos implantes como scanner extraoral, por meio da tecnologia estéreo-fotogramétrica.
Minha motivação para elaborar esta dissertação tem como objetivo principal realizar uma revisão bibliográfica acerca das vantagens e desvantagens do uso dos sistemas de captação de imagens PIC Dental® e o 3Shape® TRIOS, comparando suas indicações e resultados. Além do mais, será elaborado e recomendado um protocolo prático do uso combinado de ambos os sistemas para a captação de implantes em casos de reabilitações totais.
As bases de dados utilizadas foram a PubMed, ScienceDirect e LILACS, seguindo as normas de PRISMA. Como critérios de inclusão, foram usados apenas artigos na língua inglesa e que tivessem sido publicados num intervalo de tempo de 12 anos, ou seja, 2011 a 2023 inclusive. Foram selecionados artigos que tivessem as seguintes tipologias: pesquisa randomizada, revisão sistemática, estudo de caso, relatos de caso e capítulos de livro. Quanto aos critérios de exclusão, foram excluídos artigos que não estivessem dentro do intervalo de tempo estipulado, além de repetir-se em mais de uma base de dados e não terem relação com o tema desta revisão.
Conclui-se que que a integração dos dois sistemas pode superar as limitações do sistema PIC Dental®️. Embora o sistema mencionado seja superior ao 3Shape®️ TRIOS em termos de precisão, deve ser utilizado em combinação com o 3Shape®️ TRIOS para a colocação dos scans markers na malha de superfície, a fim de alcançar uma qualidade superior nas capturas e, consequentemente, uma maior precisão na confecção das próteses num ambiente digital como e o CAD CAM.
The use of CAD/CAM in the field of Dentistry is highly established in single and partial fixed rehabilitations, offering a high precision in this sense. Nevertheless, the use of the intraoral scanner and stereo-photogrammetry technology is increasingly used in the performance of fingerprints in total implant rehabilitations. The 3Shape® TRIOS system is an intraoral scanner used in dentistry to obtain surface fingerprints such as soft and hard oral tissues. On the other hand, the Dental® PIC allows the capture of the position of the implants as an extraoral scanner, by means of stereo-photogrammetric technology. My motivation for writing this dissertation has as its main objective to carry out a literature review about the advantages and disadvantages of the use of the PIC Dental® and 3Shape® TRIOS image capture systems, comparing their indications and results. In addition, a practical protocol for the combined use of both systems for the capture of implants in cases of total rehabilitation will be developed and recommended. The databases used were PubMed, ScienceDirect and LILACS, following the PRISMA standards. As inclusion criteria, only articles in English and that had been published within a time interval of 12 years, i.e., 2011 to 2023 inclusive, were used. Articles with the following typologies were selected: randomized research, systematic review, case study, case reports, and book chapters. Regarding the exclusion criteria, articles that were not within the stipulated time interval, in addition to being repeated in more than one database and not being related to the theme of this review, were excluded. It is concluded that the integration of the two systems can overcome the limitations of the Dental®️ PIC system. Although the mentioned system is superior to the 3Shape®️ TRIOS in terms of accuracy, it should be used in combination with the 3Shape®️ TRIOS for the placement of the scan markers on the surface mesh, in order to achieve a higher quality in the captures and, consequently, a greater precision in the making of the prostheses in a digital environment such as CAD CAM.
