ABSTRACT:
A method of forming a porcelain tooth restoration from a positive replication of the tooth structure on which the tooth restoration is to be placed. Areas of the replication are coated with a liquid preparation which substantially inhibits moisture absorption by the replication. A slurry of powdered porcelain is applied over the coated area of the replication to form at least a portion of the tooth restoration which is cured and eventually separated from the tooth replication for bonding to the tooth structure.
