METHOD OF MAKING A DENTAL PRODUCT FRAME

摘要

The invention provides a method of making a metal frame for a dental product with a polymeric model. A cast of a patient's mouth is formed. A polymerizable burn-out material is shaped on the cast and cured to form a polymeric model having a shape of a frame of a dental product. The polymeric model consists essentially of polymeric material having a flexural modulus of at least 300,000 psi. The polymeric model is invested in an investment material. The polymeric material is burned out of the polymeric model to form a mold cavity having the shape of a frame of a dental product. A metal frame of a dental product is cast in mold cavity.
