Resumo

Um dos maiores problemas para o protesista maxilofacial está em como controlar a alteração da cor das próteses no decorrer de seu uso. Para isso, pesquisas têm sido feitas, ao longo dos anos, sobre os diversos materiais e sistemas de pigmentação disponíveis no mercado, além de avaliação sobre como esses materiais se comportam ante as exposições ambientais a que são submetidos. Portanto, o presente trabalho teve a finalidade de avaliar, através da revisão de literatura desde 1969 até os dias de hoje, a alteração da cor dos materiais utilizados em próteses maxilofaciais, pigmentados ou não após o envelhecimento. Para isso, os materiais, pigmentos, método de exposição e de avaliação dos corpos-de-prova foram analisados separadamente. Pôdese observar que o silicone Silastic MDX 44210 propiciou os melhores resultados com relação à estabilidade de cor, sendo ainda considerado como um ótimo material de escolha para uso em próteses maxilofaciais. Já os pigmentos intrínsecos resultaram em menor alteração de cor. O envelhecimento ao ar livre apresentou alteração de cor menor que o envelhecimento acelerado. No entanto, é importante esclarecer que, devido à diversidade de materiais e pigmentos disponíveis em cada país e à ausência de padronização internacional, há necessidade de se pesquisar mais sobre as propriedades dos materiais, bem como a alteração de cor.

Abstract

A Maxilofacial prosthesist problem is how to control the color change of the prostheses during use. Researches have been made, along the years, about several materials and pigmentation systems available in market, besides evaluation about behavior materials in front of the environmental exhibitions that they are submitted. Therefore, the present work had the purpose of evaluating, through the literature revision since 1969 until today, the color change of the materials used in prostheses maxilofaciais pigmented or not after aging. For that, materials, pigments, exhibition and evaluation of the body proofs methods were analyzed separately. It could be observed that Silastic MDX 44210 silicone obtained the best results in color stability, being considered as a great choice material for use in maxillofacial prostheses. The outdoors aging presented smaller color change than accelerated aging. However, it is important to observe that due to the diversity of materials and available pigments in each country and absence of the international standardization, there is a need to research more about the properties of the materials, as well color change.
