摘要:
A dental hygiene (10) has a housing (12) that provides a manually deployable handle for the device and that houses a motor (14) that drives both a brush agitating drive mechanism (16) and a liquid dispensing pump mechanism (18). The housing (12) has a tool mount (20) that interchangably mounts in operable relation with the drive mechanism and with the pump mechanism any one of a dental brush tool (22) and a dental spray tool (24). The brush tool and the drive mechanism preferably are arranged to agitatingly drive two sets of brush elements (26) and (28) oppositely, preferably with back and forth rotation of individual brush tufts.
摘要:
A novel dental implant comprising an implant fixture assembly for attachment to a jaw bone at a first end thereof, the fixture assembly having a longitudinal axis; an abutment for mounting on a second end of the fixture assembly, the abutment having a longitudinal axis; and a fastener for connecting the abutment to the second end of the implant fixture assembly such that the abutment is movable on the second end of the implant fixture assembly and, upon disposition of the abutment axis at a selected angle to the implant fixture assembly axis, for connecting the abutment to the second end of the implant fixture assembly such that the abutment is fixed on the implant fixture assembly at the selected angle. A novel tool for deploying the novel dental implant is also disclosed. And a novel method for effecting a dental restoration is also disclosed.
摘要:
A manually deployable power tool for dental treatment and other uses drives an output shaft with continuous rotary motion, combined with selected axial reciprocation of adjustable stroke length. The drive mechanism for imparting this combined motion to the output shaft has a single rotary input drive coupled with an adjustable cam mechanism. The cam mechanism produces the reciprocating motion in response to the driven rotation of the output shaft. The tool drive mechanism has a high degree of axial symmetry, and is arranged to facilitate the delivery of liquid material to the output, tool-carrying end of the output shaft.
