  • Patent number: 12263051
    Abstract: A dental prophylaxis tool handpiece includes a motor section having a first connector; a sleeve section having a second connector with a first end extending over a portion of the motor section and engaging a prophylaxis tool at a second end; the first and second connector configured for engagement with each other and configured to limit relative axial movement of the sleeve section relative to the motor section while allowing for free rotational movement of the sleeve section relative to the motor section; and upon engagement of the sleeve section with the motor section, a portion of the motor portion is covered to substantially isolate the portion of the motor section from contaminants. Other embodiments incorporate a positive air pressure feature and/or an ozone generator. Associated methods of preventing contamination of at least a distal portion of a motor section of a prophylaxis tool handpiece are also described.

  • Patent number: 10765491
    Abstract: 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.

  • Patent number: 10206563
    Abstract: 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.
