The Contact Perfect MOD Solution is a Tofflemire-type Matrix Band that features dual, opposing windows to allow for resin displacement, allowing the clinicians to achieve predictable, contoured, class 2 contacts every time. The exposed windows permit buccal/lingual inter-proximal curing to ensure complete depth of cure with bulk filled resins, and full coverage of the tooth allows for simultaneous cusp buildup or replacement. In addition, with the absence of the conventional matrix wall, there is no need for excessive hyper-separation of teeth to achieve contact.
