Dental instruments with stress relief

The present invention relates to a unique solution for relieving repetitive stress to dental professionals during the course of a day and is directed to sets of identical instruments, having handles made with varying diameters for grasping, designed to be used interchangeably throughout the day, thus cutting down on the repetitive grasping action through the change of grasp. Therefore, even if a dental professional uses the same type of instrument throughout the day, the hands, wrists and elbows can experience varying rather than repetitive action because the positioning of the hands, wrists and elbows are interchanging throughout the day. The dental instrument may also be ergonomically designed. Additionally, the instrument may also have a vibratory module. Further, a rotator may also be implemented.

Method and device for placing dental implants

The invention relates to a method and device for placing implants (1) using a surgical template (11) which is made from tomographic cuts in the patient's jawbone (7). According to the invention, step drills (4) and calibrating drills (5), having a single standard diameter for each type of implant (1), are guided through drill bushings (18) which are inserted into bores (15) in the template (11) in order to produce any drilling sequence corresponding to an implant plan. The penetration depth of the drills (4, 5) is controlled by the height of the bores (15) or by the drill rings (21). The aforementioned template (11) bores (15) serve as a guide for the precise placement of the implants (1) owing to the adapted implant supports (3). Moreover, washers (23), which are mounted around the implant supports (3), limit compression in relation to the implants (1) while said implants are being placed (20). The above-mentioned characteristics serve to limit the required number of drills (4, 5) and implant supports (3) to the longest models only.

The selected tool in communication with a source of powered motion and mounted in and supported by a hand piece which is guided into the mouth of the horse. The cutting surface of the powered tool is partially guarded so as to protect fleshy portions of the horse's mouth from being engaged by the cutting surface. The hand piece provides for quick on and off attachment of a selected cutting surface for maintenance of a preselected portion of teeth within the same hand piece or another hand piece sized to ease access to the next selected portion of the horse's mouth. The selected hand piece arrangement may further incorporate a vacuum channel whereby the tooth dust and debris created by the powered cutting surface removing a portion of tooth is sucked out of the mouth of the horse. The motion of the tooth surface removal tool may be changed from rotary to powered reciprocating motion for a selected portion of the teeth or changed to be at a preselected angle. Attaching the powered drive to the rotary cutting surface by means of an adjustable clutch further enhances protection from injury to the inside of the mouth of the horse.
