Clinical Relevance

  Proper configuration of the proximal surface of a Class II composite restoration is essential for the preservation of dental and periodontal tissues and subsequent long-term success. Adequately customized or designed wedges can assist in reproducing an imitation of natural form in the interproximal area and ensure sufficient contact tightness with the adjacent tooth.

 SUMMARY

  Clinical experience supports the notion that the restoration of MOD cavities may pose a challenge to the practitioner. Proper placement of precontoured matrices and commercial wedges help the clinician to establish an optimal emergence profile and sufficient contours. However, the presence of proximal concavities in premolars or molars can turn the reproduction of previous cervical architecture into an even more demanding task. Wedges with customized form or adequate design can precisely conform the matrix to the cavosurface area and prevent any gap formation. This article presents two different options that allow for successful and predictable reestablishing of anatomically correct contours and optimal proximal contacts in posterior teeth with proximal concavities.
