Research Abstract

In the present study, to develop a glueless retentive material for the denture, two prototypes of cohesive silicone were made and their mechanical properties and level of instantaneous adhesions were investigated. Two prototypes, High cohesion (H) and Middle cohesion(M), were made to be cured by using equivalent amount of a catalyst and base silicone, which improved manipulation of the silicone and bubble entrapment. Mechanical properties and the level of adhesions for (H) were same level as those for control. Furtehr investigation and improvement are necessary, for example, put in hydrophilic materials to show adhesive characteristics even when water is existent.
