SONICSYS approx: an innovative addition to the restorative continuum.

When cost and aesthetics form part of the treatment decision process, patients with Class II defects are invariably directed toward direct restorative options. Due to the mechanical stresses generated by polymerization shrinkage, direct composite resin restorations can be ineffective treatment modalities. One addition to the restorative continuum utilizes shaped, sonically driven, diamond-coated preparation tips to adjust the cavity form to fit presized ceramic inlay restorations. This article introduces techniques that allow proper contacts and contour to be achieved utilizing this addition to the restorative continuum.
