Dental system for root and root tip extraction
Abstract:
A compact, easily transportable dental system to permit root and root tip extractions from human and animal patients including those who are unable to visit an oral surgeon or veterinarian at a traditional office. An extraction bur having a lifting ball is embedded within and stands upwardly from the root or root tip to be extracted. The extraction bur is detachably connected to and rotated into the root/tip by a bur implanting device. A bur ejector is slidable through the bur implanting device to cause the extraction bur to be released therefrom once the bur has been implanted in the patient's root/tip. A universal fulcrum tray covers the root/tip and surrounds the patient's adjacent teeth during the extraction process. The upstanding extraction bur and the lifting ball thereof project through one of a pair of slots formed in the universal fulcrum tray. An extracting instrument having a pivot surface rotates over the universal fulcrum tray to apply a lifting force to the lifting ball of the extraction bur to pull the bur upwardly and the root/tip outwardly from its root socket.
