Resumo
Os autores verificaram a alteração de peso que as resinas para facetas estéticas de próteses fixas apresentam quando imersas em água destilada e mantidas a seco por diferentes intervalos de tempo. Os resultados evidenciaram que a alteração de peso negativa foi maior na condição em que os corpos de prova eram mantidos a seco, havendo variação de comportamento entre os materiais. Houve influência do tempo de armazenamento apenas no intervalo das primeiras 24 horas.

Abstract
The authors verified the alteration of weight for the resins utilized on aesthetic facets of fixed prosthesis either immersed or not in distilled water for different gaps of time. The results showed that the negative alteration of weight was greater when the samples were maintained dry. It was noted variation of behaviour among the materials and the time of warehousing influenced only for the first 24 hours.
