Method of making hydrophilic non-sweating polymerizable dental impression material

A method of making an impression, comprising:

• mixing two components of a hydrophilic non-sweating polymerizable polyorganosiloxane separation stable putty material, one component including a catalyst for polymerization, said putty material, comprising:
• a resin, containing vinyl groups, a plasticizer and a surfactant;
• said surfactant being effective to emulsify said plasticizer,
• applying a low viscosity material,
• applying said putty material over the low viscosity material,
• whereby the low viscosity material is forced into the minute details of the patient's oral tissues,
• hardening said putty material and said low viscosity material within about five minutes to form an impression of said patient's oral tissues, and
• removing said impression from said patient's oral tissues.

A process, comprising:

• providing two components of a hydrophilic non-sweating polymerizable polyorganosiloxane separation stable composition, one component including a catalyst for polymerization, said composition, comprising:
• a resin having vinyl groups, a plasticizer and a surfactant, said surfactant being effective to emulsify said plasticizer,
• pressing said composition, and
• polymerizing said resin to form a dental impression of solid polymeric material.
