Julldent Inter Proximal Discs Set of 3 Inter Proximal Discs are stainless-steel proximal separator discs that help create space by breaking through set cement or adjusting tight contacts and also by removing excess materials from interproximal areas. Simply rock Inter Proximal Discs through the contact to break through residual cement or to settle teeth - no 'sawing' that causes abrasive enamel damage on both teeth. After breaking through cement it can quickly remove excess material while protecting enamel on the adjacent tooth. Interproximal Discs also enable easier placement of matrix bands. Smooth Interproximal Discs are also used to break contacts or to settle teeth when no removal of cement or enamel is desired. The thin, smooth disc easily slides between teeth. This design protects the teeth from unwanted abrasion damage, where bacteria and plaque can adhere and accumulate. Serrated edges can cause damage to the enamel of both teeth, just as saw blades abraid the surfaces on both sides of a cut. INDICATIONS FOR USE: To create space in tight contact interproximal areas, adjust, break, or smooth contacts and remove excess bonding agents, resins, or types of cement from interproximal areas. To help settle teeth in a crowded arch or during orthodontic treatment.
