Abstract
The present invention relates to a dental safe edge interproximal disk for stripping the interproximal contact area of adjacent teeth wherein an abrasively coated circular disk has an uncoated periphery which facilitates the initial entry of the disk between the contact points.
Claims20
a safe edge IPR disk comprising:
- a circular disk with an axial center, an axial periphery, an outside planar surface and an inside planar surface;
- a rod-like mandrel with a driving end and a working end, the driving end adapted to be mounted to a powered dental handpiece and the working end attached at a right angle to the circular disk at the axial center of the inside planar surface;
- and
- an abrasive coated on the planar surfaces of the circular disk extending from the disk axial center to an uncoated planar axial periphery wherein the uncoated periphery is the initial penetration when the circular disk is placed between the contact points of adjacent teeth.

A method for polishing interproximal contact areas of adjacent teeth comprising the steps of:
- providing a polishing device comprising (a) a disc-shaped body having a thickness of from about 0.1 to 0.7 millimeters wherein said body is adapted to be connected to a mandrel which is in turn attached to a driving means;
- and (b) an abrasive layer is coated on one side of the disk-shaped body except for an uncoated periphery;
- driving said polishing device by a driving means;
- and
- placing the uncoated periphery of the disk-shaped body into the interproximal contact area of adjacent teeth;
- rotating the disk-shaped body;
- penetrating the interproximal contact area until the abrasive layer contacts the tooth;
- and
- polishing the interproximal area of the tooth,
