Directa ProxyPal Matrix Band, 36pcs
The pre-shaped progressive curvature aids to create incisial fillings with a correct anatomical shape. The proximal curvature differs from tooth to tooth. In order to achieve a perfect filling the matrix has been designed so that the curvature of the matrix escalates linearly along its total length. On one end the curvature is subtle which is ideal for lower jaw incisors. On the other end the matrix curvature is distinct thus suitable i.e. a diastema closure. By pushing/pulling the matrix it is easy to find a suitable position for every tooth. The matrix has a cervical edge which inserts into the soft tissue pocket. The cervical edge prevents moisture from the surrounding tissue that interfers with the cavity and stabilizes the matrix during insertion of filling material. Indications for use: Class IV, Large Class III, Closure of diastema. How to Use: After preparation of the cavity, carefully apply the matrix band so that the cervical edge goes into the pocket. By pushing/pulling search the bands ideal position for the best approximal shape. Cut the matrix if needed. The contour design stabilizes the matrix during the entire process. The band can sometimes be fixed by allowing it to go around the palatinal surface and back into the interdental space on the other side. This technique can also be used with double approximal fillings.
