Contact Perfect matrix bands take you back to basics with a conventional Tofflemire-type retainer and a matrix band with a removable window that allows the resin to flow to perfect contact with the adjacent tooth. This ingeniously designed 0.001-in matrix band makes the process easier, faster, and better. Upon removal, it separates around the contact point, leaving the marginal ridge intact.
