Abstract:
A process for fabricating an indirect dental restorative comprising the sequential steps of:(a) forming a first, pre-operative impression of a tooth to be restored using a first polyvinyl silicone (PVS) material disposed in a clear tray; (b) forming a final post-operative impression of the tooth in a second PVS material and allowing the material to dry; (c) pouring a low viscosity third PVS material into the final impression, the third material forming a model tooth; (d) applying a fourth PVS material onto the third PVS material, the fourth material having a viscosity higher than the viscosity of the third material, the fourth material providing a base for the model tooth; (e) removing the model tooth and base from the final impression; (f) fitting the model tooth into the pre-operative impression made from the first PVS material; (g) applying composite material to the pre-operative impression; (h) inserting the model tooth into the composite-containing pre-operative impression, forming a matrix; and (i) curing the composite in the matrix in a single apparatus for conducting one of light, heat, or both light and heat cure of the dental composite.
