STENTS AND METHOD FOR DENTAL RESTORATION USING SAME

摘要

A method for dental restoration that includes disposing a flowable and curable tooth restoration composition into an open cavity of a stent that defines contours of a final design model of a patient's teeth and includes an interproximal contact that has been thinned along an interproximal contact zone but not separated, seating the stent on the patient's teeth such that the flowable and curable tooth restoration composition fills a space between at least one tooth to be restored and the stent, initiating curing of the flowable and curable tooth restoration composition in the stent such that the composition bonds to the at least one tooth to be restored and forms at least one restored tooth and removing the stent from the patient's teeth to expose the at least one restored tooth.

主权项

1. A method for forming a stent for dental restoration, the method comprising:
applying a first curable material onto a final design model of a patient's teeth and proximal soft tissues, said first curable material
(a) covering a plurality of teeth including at least one tooth to be restored, and(b) contacting the proximal soft tissues facial and lingual to the at least one tooth to be restored; curing the first curable material on the final design model under pressure to form a cured initial mold; forming an opening in the cured initial mold, said opening exposing at least a portion of the at least one tooth to be restored when the cured initial mold is seated on the final design model of the patient's teeth; applying a second curable material onto the exposed at least one tooth to be restored and the cured initial mold when the cured initial mold is seated on the final design model of the patient's teeth; covering the second curable material with a cover film; curing the second curable material on the final design model and the cured initial mold under pressure to form the stent having a first portion formed of the first curable material and a second portion formed of the second curable material; and removing the stent from the final design model to expose a mold cavity that defines contours of the final design model of the patient's teeth and proximal soft tissues.
