Abstract

This study verified the effect of the association gypsum or silicone investment support materials and water immersion on the relative tooth movement in complete dentures. Wax record bases with teeth were assigned to 2 groups (n=10): 1- type III dental stone (control), and 2- condensation silicone. Linear distances (mm) between teeth were recorded after deflasking and after water storage for 1 week, 1 month and 3 months. With the exception of the silicone for the pre-molar distance after water storage for 3 months, the association between the type of investment and period of water storage did not alter the distances between teeth.
KEY WORDS: Investment material, Tooth movement, Complete dentures, Deflasking, Water storage.
