ProxyPal from Directa is a pre-shaped matrix with a progressive curvature that helps in the creating the correct anatomical shape for incisal fillings. The curvature of the matrix escalates linearly along its total length. On one end the curvature is minimal, which is best for lower incisors. On the other end, the curvature is sharper for treatments such as a diastema closure. ProxyPal is indicated for Class IV and large Class III restorations as well as diastema closure.
