CoForm ™ large matrix system kit by Directa assists in the placing of composite materials and assisting in creating precise fillings. Product Features: Transparent matrices made of celluloid plastic, so they will not adhere to composite and will speed up class IV restorations. Matrixes ready cut for mesial and distal corners of anterior teeth and canines. Ideal for forming composite restorations as fractured incisive edges. TO USE: Press them onto uncured composite to give restoration the anatomy of a healthy tooth. Finally cure the composite through the clear matrix. Kit Includes: 128 matrix strips (8 of each size: 11 mesial/distal, 21 mesial/distal, 12 mesial/distal, 22 mesial/distal, 13 mesial/distal, 23 mesial/distal, 31-32 mesial/distal, 41-42 mesial/distal). Instructions (PDF): Compare the size of CoForm to the fractured tooth and then choose the right matrix. Apply composite material in the CoForm and press into place with a slight moving motion, so you avoid bubbles. Prewedge and insert CoForm in place. If needed, cut the plastic matrix to make adjustments. Prepare the enamel, bevel 0,5-1 mm for a maximal enamel bonding surface. Then etch and bond as usual. Light cure through the CoForm matrix. Lastly peel off after curing, correct excess material, shape, and polish to complete the restoration. NOTE: CoForm Small CoForm Matrix System Kit Available (see #69-461)
