主权项

1. A method for the restoration of a tooth having an original shape including a top surface and an interproximal surface, the method comprising:
(a) removing a portion of the top surface of the tooth and a portion of the interproximal surface of the tooth to form a hollow Class II cavity preparation, the cavity preparation extending from the top surface to the interproximal surface of the tooth; (b) surrounding the removed portion of the interproximal surface of the tooth with a matrix; (c) placing a light-curable resin tooth bonding agent into the cavity preparation; (d) injecting a light-curable flowable composite into the cavity preparation to create a pool of the flowable composite in the cavity preparation wherein the light-curable resin tooth bonding agent and the light-curable flowable composite are not cured at this step; (e) after step (d), extruding a light-curable paste composite resin into the pool of the flowable composite before light curing the pool of the flowable composite thereby displacing some of the flowable composite; and (f) simultaneously light curing the bonding agent and the flowable composite and the paste composite resin contained in the cavity preparation.
