Abstract
A cutting blade having a pair of razor-sharp cutting edges and adapted to be oscillated back and forth in order to cut through the periodontal ligaments which surround a tooth root of a patient during dental surgery so that the root or a portion of a tooth root can be removed from the patient's jawbone. The cutting blade has a connecting shaft at one end by which the blade can be coupled to the driver head of an oscillating dental handpiece. Located opposite the connecting shaft is a cutting end having a tissue debris transfer canal at the bottom or inside thereof and a smooth tissue gliding surface at the top or outside. A positioning collar surrounds the connecting shaft to provide to the oral surgeon a visual indication of the alignment of the pair of cutting edges of the cutting blade relative to the tissue to be cut.
