| 摘要 | A method and apparatus for restoring badly discolored, fractured or cariously involved teeth by etching desirable parts of the enamel surface of the tooth and by adhering to the tooth a properly colored polymerized, preformed plastic facing that has a pleasing cosmetic appearance or corresponds to the coloring of adjacent teeth as desired. The etched surface of the tooth, the inside surface of the facing material and the exposed surface of the facing material including the joint between the facing material and the enamel of the tooth are coated with a controlled curing dental adhesive material that may be selectively cured in place, such as by ultra-violet activation. The voids between the tooth and the facing material may be filled with a controlled curing dental filler material that may also be molded about the joint between the tooth enamel and the facing material. The dental filler material may also be of the type that is cured in place such as by curing following ultra-violet activation. Facings bonded to the enamel of abutment teeth may be employed for support of pontics without necessitating preparation of abutment teeth with bridgework support crowns. Connected facings may also be employed for periodontic splinting. | ||||||
