The PerForm™ Proximal Contact Instrument is a cure-through contact forming instrument you press directly into the first increment of uncured composite on Class II restorations. Apply mesial or distal pressure to place the interproximal contact where you want and cure.PerForm allows you complete control over the location—both the height and breadth—of the contact on Class II restorations. Whether you’re using one of the popular sectional matrix systems, traditional Tofflemire-style matrices or retainerless systems like ReelMatrix.
