Abstract
This invention relates to methods and compositions for single component photoinitiated dental impression materials. The impression material is workable in its pre-cured state, cures rapidly upon exposure to light, and exhibits desirable processing conditions such as short setting time, long working time, no void formation, good wettability, mechanical properties, and detail reproduction.
Claims26
A method for making a dental impression mold comprising the steps of:
- exposing an area for implant;
- applying and positioning a photochemically curable impression material comprising a thiol monomer and a vinyl monomer to said exposed area;
- applying sufficient pressure to seat and mold the impression material in a desired size and shape;
- and
- curing the impression material using a light source to form the dental impression mold.
A dental impression material composition, the composition comprising a thiol monomer and a vinyl monomer.
A method of making an artificial tooth, the method comprising:
- removing an amount of an impression material from a container, the impression material comprising a thiol monomer and a vinyl monomer;
- placing an amount of impression material in a mold tray;
- making an impression in the impression material, the impression having the desired shape of the artificial tooth;
- photopolymerizing the impression material to create a mold including a set impression of the artificial tooth;
- and
- creating at least one artificial tooth from the mold by placing an artificial tooth compound into the set impression and solidifying the artificial tooth compound.
