Avaliação da percepção estética de prótese óculo-palpebral confeccionada pelo método convencional e pelo sistema CAD/CAM

Prototipagem rápida
Abstract in Portuguese
O uso do Sistema CAD/CAM já é bastante consagrado na Odontologia, não sendo diferente na reabilitação facial. Traz diversas facilidades, porém poucos trabalhos relatam as reabilitações da região óculo-palpebral. Nesse estudo, a aquisição de imagem tridimensional foi feita com o uso de um escâner de superfície a laser, FARO Edge ScanArm®, protegendo-se o olho contralateral com uso de lente gelatinosa preta; método que demonstrou eficiência na obtenção de imagem de pálpebras abertas para confecção de protótipo reverso. Foram selecionados 10 pacientes com exenteração de órbita, de ambos os gêneros, sendo 5 com mutilação à esquerda e 5 à direita. Todos os pacientes receberam duas próteses óculo-palpebrais, uma confeccionada pelo método convencional e outra pelo sistema CAD/CAM. As reabilitações foram registradas fotograficamente e avaliadas por 30 indivíduos leigos, 3 especialistas em prótese bucomaxilofacial e pelos próprios pacientes, usando-se a Escala VAS. Para avaliar a variação intraexaminador, 15 leigos repetiram a avaliação com intervalo de uma semana, assim como os 3 especialistas. Os resultados demonstraram consistência interna e uma boa reprodutibilidade dos dados em todos os grupos. A percepção estética foi melhor avaliada nas próteses obtidas pelo método convencional; entretanto, a relevância da diferença observada entre os dois métodos foi avaliada como razoável.

Abstract in English
The use of CAD/CAM system is already an established method in Dentistry, no different in facial rehabilitation. It brings several facilities, but few studies have already reported the rehabilitations of the orbital area. In this research the acquisition of the three dimensional image was taken using a surface laser scanner, FARO Edge ScanArm®, protecting the contralateral eye with the use of a black gelatinous contact lens; this method has demonstrated effectiveness in getting image with open eyelids for making reverse prototype. 10 patients were select with orbit exenteration, of both genders, 5 with left mutilation and 5 with right. All patients received two oculopalpebral prostheses, one obtained by the conventional method and another by the CAD/CAM system. The rehabilitations were photo registrated and assessed by 30 lay assessors, 3 bucomaxillofacial prosthetic specialists and by the patients themselves using the VAS Scale. To evaluate the intraexaminer variation, 15 lay assessors repeated the evaluation with one week interval, as did the specialists. The results demonstrated good interexaminer variation and reproducibility of data in all groups. The aesthetic perception was better evaluated in prostheses obtained by the conventional method; however, the relevance of difference between the two methods was assessed as a reasonable one.
