Stainless steel matrices designed to fit the contour of the anterior teeth labially, palatally and proximally. Removes the need to cut or modify existing posterior sectional matrices. Indicated for anterior restorations involving the proximal walls (Class III and IV, peg-shaped lateral incisors, diastema closures, partial and total veneering). Unica Proximal Deep is designed for perio applications with a flat papilla. Faithful reproduction of the labial, palatal and proximal contours. Universal shape and contour for upper and lower mesial and distal teeth that considerably simplify and expedite anterior restorations. Allows unobstructed visibility and operatory field access, even when multiple matrices are placed at the same time. Self-stabilising. Longer cervical extensions than posterior sectional matrices.
