Resumo
O crescente mercado da implantodontia faz aumentar o interesse por parte da indústria em suprir as necessidades encontradas pelos implantodontistas. Como resultado deste crescimento, muitas empresas tem criado novos modelos (sistema) de implantes todos os anos em todo o mundo. Em casos onde por alguma razão exista a necessidade de substituição da prótese e que não é possível ter acesso ao prontuário do paciente, para que se possa verificar a marca e o modelo do implante utilizado, o cirurgião dentista passa a ter um grande desafio. O objetivo deste trabalho foi desenvolver uma metodologia, para auxiliar a identificação de implantes dentários, pôr meio da comparação entre imagens 3D de um banco de imagens com uma imagem 3D obtida por meio do molde de um implante físico, com um silicone de adição e posteriormente digitalizada. Materiais e métodos: Foram realizadas 10 moldagens da conexão protética de um implante do tipo hexágono interno e de outro cone morse com um silicone de adição extra leve, esta moldagens foram digitalizadas através de um escâner de bancada e separadas em dois grupos teste Grupo 1 (Implante Hexágono Interno - Implacil de Bortoli, São Paulo - Brasil), e grupo 2 - Implante Cone Morse (Implacil de Bortoli, São Paulo - Brasil), estes grupos foram comparados com os seus respectivos grupos de controle. Resultados: Foram analisadas medidas lineares de 36 pontos criados virtualmente através do Software de Avaliação para Dados de Medição 3D GOM Profissional, estes pontos foram previamente determinados ao longo da conexão protética de ambos os modelos de implantes testados. Os resultados foram descritos por medidas de posição (média) e escala (desvio padrão). Avaliações das imagens de cada molde com sua referência (HI e CM) foram descritas por gráficos de Bland-Altman (Altman, 2007), e para cada molde e de forma conjunta, foram apresentados Coeficientes de Concordância de Lin (Lin, 1989) e Coeficientes de Correlação de Pearson (Bussab, Morettin, 2006) para descrever a relação entre as medidas observadas pelo método em teste com as respectivas referências. Conclusão: Diante dos resultados encontrados no presente estudo, acreditamos que o método proposto seja satisfatório, para a identificação de implantes dentários.
The growing market of implantodontics increases the interest on the part of the industry in supplying the needs found by implantodontists. As a result of this growth, many companies have created new implant models (system) every year around the world. In cases where, for some reason, there is a need to replace the prosthesis and it is not possible to have access to the patient's medical record, in order to verify the brand and model of the implant used, the dental surgeon now has a great challenge. The objective of this work was to develop a methodology to assist in the identification of dental implants, by comparing 3D images from an image bank with a 3D image obtained through the mold of a physical implant, with an addition silicone and subsequently scanned. Materials and methods: 10 impressions were taken of the prosthetic connection of an internal hexagon implant and another morse cone with an extra light addition silicone, these impressions were digitized through a bench scanner and separated into two test groups Group 1 ( Internal Hexagon Implant - Implacil de Bortoli, São Paulo - Brazil), and group 2 - Cone Morse Implant (Implacil de Bortoli, São Paulo - Brazil), these groups were compared with their respective control groups. Results: Linear measurements of 36 points created virtually using the GOM Professional 3D Measurement Data Evaluation Software were analyzed, these points were previously determined along the prosthetic connection of both tested implant models. The results were described by measurements of position (mean) and scale (standard deviation). Evaluations of the images of each mold with its reference (HI and CM) were described by Bland-Altman graphics (Altman, 2007), and for each mold and jointly, Lin's Coefficients of Agreement (Lin, 1989) and Pearson Correlation Coefficients (Bussab, Morettin, 2006) to describe the relationship between the measurements observed by the method under test and the respective references. Conclusion: In view of the results found in this study, we believe that the proposed method is satisfactory for the identification of dental implants.
