The centripetal build-up for composite resin posterior restorations.

The paper introduces a new technique for creating Class II posterior composite restorations--the centripetal build-up. This technique replaces the lost tooth structure from the periphery towards the center of the cavity, thereby achieving better marginal adaptation to the gingival floor. Since overfilling is rare, rotary finishing is minimized. This method allows the creation of long-term aesthetic posterior composite restorations, while utilizing conventional auxiliary (ie, metal matrix bands and wooden wedges) in operative dentistry. The learning objective of this article is to introduce this new technique to a wider segment of the dental profession.
