Resumo
O processo de impressão tridimensional (3D) vem sendo amplamente utilizada na odontologia, no entanto, se faz necessário uma padronização com a finalidade de validar a acurácia desse processo, permitindo a realização de tratamentos reabilitadores e planejamentos cirúrgicos com segurança e mais conforto para o paciente. O objetivo do presente estudo foi avaliar a acurácia de modelos impressos, e o posicionamento de análogos digitais após desenho em software, com dois desenhos de bases diferentes (aberta e fechada). O método consistiu na confecção de modelos impressos (n=6), a partir de um modelo mestre de arco completo contendo um análogo de implante na região dos elementos 16, 24 e 26. O modelo mestre foi escaneado com um escâner intraoral, e transformado em um modelo digital a partir de um software de desenho. Após o desenho estes modelos foram impressos em impressora 3D, utilizando-se a mesma resina para ambos os desenhos. Após a impressão os modelos foram novamente escaneados e sobrepostos ao modelo mestre em software de análise, e foram realizadas as medidas da discrepância vertical do posicionamento do análogo. Para cada análogo, foram realizadas 3 medidas em milímetros e obtida sua média. Após a análise, pode-se observar que modelos de base totalmente fechada apresentaram menor variação no posicionamento vertical dos análogos de implante, quando comparado com os modelos de base totalmente aberta.
The three-dimensional (3D) printing process has been widely used in dentistry, however, standardization is necessary in order to validate the accuracy of this process, allowing the performance of rehabilitative treatments and surgical planning with safety and more comfort for the patient. The aim of the present study was to evaluate the precision of printed models, and the positioning of digital analogues after drawing in software using two different base designs (opened and closed). The method consisted of printing models (n=6), from a full-arch master model containing an implant analog in the region of elements 16, 24 and 26. The master model was scanned with an intraoral scanner, and were converted into a digital model from a design software. This model was printed in a 3D printer, with two different base designs, using the same resin for both designs. After printing, the models were scanned again and superimposed on the master model in analysis software, and measurements of the vertical discrepancy of the analog positioning were performed. For each analogue, 3 measurements in mm were performed and their average was obtained. After the analysis, it can be seen that the models with a completely closed base presented less variation in the vertical positioning of the analogues when compared to the models with a completely open base.
