摘要：
The present invention is directed to dental prophylaxis devices that improve portability, maneuverability and aid in retaining clean conditions for use on dental patients, particularly to dental handpieces. The present invention is also directed prophylaxis or prophy angles for use with such handpieces. In general, a dental prophylaxis device includes a handpiece and a prophy angle which includes a driven shaft and a prophy cup attached for rotation thereto. The handpiece generally includes a body which houses a rotational source coupled to an output shaft which couples to the driven shaft in the prophy angle via angled gear interfaces on the output shaft and the driven shaft.
