Matrix Systems For Direct Restorative Materials
Class II (interproximal) decay and/or a failing restoration that involves a posterior proximal surface is still a common finding in most dental patients. Many of these problems can be handled utilizing directly placed restorative materials. The challenge for the dentist has always been to recreate contact to the adjacent tooth and at the same time restore proper interproximal anatomic form given the limitations of conventional matrix systems. The thickness of the matrix band and the ability to compress the periodontal ligaments of the tooth being restored and the one adjacent to it can sometimes make the restoration of proximal tooth contact arduous at best.
