Silicone Rubber Base Impression Material

Reproduction of oral detail accuracy of stone models a variety of laboratory models has been used to evaluate the accuracy of rubber impression materials.

Silicone rubber base impression material.

It was the first type of silicone impression material. Marcinak et al 1980. The accuracy and dimensional stability of a silicone rubber base impression material have been investigated. 21 condensation silicone impression material reisbick and matyas 1975.

Dispensing of mercaptan rubber impression materials. Light bodied heavy bodied mixing procedures loading of both mixtures into syringes and trays. Stauffer et al 1976. Also known as conventional silicones.

Often polysulfide materials are called rubber or rubber base materials even though polyether and silicone materials are also rubber materials. Setting occurs in room temp so called as rtv silicones. Nonrecovery of silicone after setting under compression in a tray is less than 1 per cent compared to approximately 2 per cent for a mercaptan and approximately 4 per cent for alginate irreversible hydrocolloid materials. Augsburger et al 1981.
