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.

A dental mirror includes a handle having a lumen, a mirror housing attached to the handle, a mirror cartridge for insertion through a cartridge opening of the mirror housing, a drive shaft rotatably held within the handle, and a film-roller rotatably attached to a film-roller bearing. The mirror cartridge includes a base, a film-roller bearing connected to the base, a film support structure connected to the base, and a film surrounding the film support structure. A distal end of the drive shaft and a proximal end of the film-roller are rotatably linked such that a rotation of the drive shaft rotates the film-roller causing the film to move relative to the film support structure.

A dental system comprises a dental prophy angle and an adapter. The prophy angle includes a housing and a latch mechanism. The adapter is configured to drive the prophy angle. The latch mechanism includes a lever and a first latch element, which are both defined by a pair of opposing U-shaped slots within the housing, such that free ends of one of the pair of opposing U-shaped slots are disposed between free ends of the other of the pair of opposing U-shaped slots. The adapter includes a nose having a second latch element and a depression proximate to the second latch element. Upon the first latch element mating with the second latch element, the depression is positioned adjacent the lever.
A dental system comprises a dental prophy angle and an adjustable angle adapter. The prophy angle includes a housing and a guard with a concave inner surface. The adapter is configured to drive the prophy angle and the adapter includes a body, a nose, and an outer joint. The nose is configured to receive a portion of a prophy angle. The body is adjustably connected to the nose. The outer joint includes a ball portion connected to the nose, and a ball receiver positioned on the body. The ball receiver includes a first portion coupled to a first end of the body and a second portion attachable to the first portion. The nose is rotatable relative to the body into at least a first configuration and a second configuration. The concave inner surface of the guard engages a convex outer surface of the ball receiver.

The present invention provides a dental prophylaxis angle that includes a housing, a drive shaft, and a rotor. The housing may define a first bore and a second bore in communication with the first bore. The drive shaft is positionable in the first bore and may include a distal bearing surface. The rotor is positionable in the second bore and can be driven by the drive shaft. Further, the rotor rotates about a first axis. The second bore can further include a side surface, a plane perpendicular to the first axis that intersects both the side surface and the distal bearing surface. The drive shaft and the side surface of the second bore can operate together, against a common surface of the rotor, to prevent removal of the rotor from the second bore in a direction along the first axis.
A dental prophy angle includes a housing and a rotor. The housing defines a first bore and a second bore in communication with the first bore, and rotor is disposed within the second bore. The rotor includes a gearing system, and rotor includes a lock having a lock channel configured to receive a tip of a drive shaft. The housing includes a lock receiver for receiving the lock receiver permits rotation of the lock within the lock receiver and restrains linear movement of the lock in a direction substantially parallel to a rotational axis of the rotor.
