METHOD FOR REMOVAL OF DENTAL CEMENT

摘要

In a method of restoring a tooth, the present invention provides a technique for the removal of cement after bonding a dental construct to a tooth. The effect of 5 cement removal techniques were determined by means of an in vitro study, using extracted human teeth. The best results in terms of leakage scores and interface contour were obtained by the technique disclosed, comprising the following steps: after placement of the construct on the tooth, removing excess cement with a soft, pointed brush, brushing the dental margins with a photocurable dental resin cement which is the same as or different from the dental cement used to bond the construct to the tooth; and, light curing the photocurable dental resin cement. When using resin or resin ionomer dental cements, the technique of cement removal disclosed yields improved marginal adaptation of the cement and a good marginal seal.
