Dental Handpiece and Prophy Angle

摘要

A combination includes a dental handpiece and a prophy angle. The dental handpiece includes a nosecone threadably connected to the dental handpiece. The prophy angle includes a proximal body that matingly attaches to the nosecone. A plurality of elongated torque members are formed on each of the prophy angle proximal body and the nosecone. Each of the torque members is a male torque member or a female torque member and each male torque member formed on one of the prophy angle proximal body and the nosecone matingly couples with a female torque member formed on the other of the nosecone and the prophy angle proximal body. The prophy angle, including the plurality of elongated torque members formed on the prophy angle, is formed to also be attachable to a known standard doriot-style nosecone. Other specific features of the handpiece and prophy angle are also disclosed.

1. A combination of a dental handpiece and a prophy angle comprising:
the dental handpiece including a body and a nosecone threadably connected to a distal portion of the dental handpiece; the prophy angle including a proximal body such that the prophy angle proximal body is matingly attached to the nosecone; a plurality of elongated torque members formed on each of the prophy angle proximal body and the nosecone, wherein each of the plurality of elongated torque members is one of a male torque member and a female torque member, such that each male torque member formed on one of the prophy angle proximal body and the nosecone matingly couples with a female torque member formed on the other of the nosecone and the prophy angle proximal body; and wherein the prophy angle, including the plurality of elongated torque members formed on the prophy angle, is formed to also be attachable to a known standard doriot-style nosecone.
