Abstract: Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth.

A tapered region may be adjacent the apical end. On the apical part one or more taps are provided so the tap is cutting when rotating, clockwise and counter-clockwise. The implant can have at least one variable profile helical thread that extends along the tapered region. The implant can have also micro-threads below the main threads, a gradual compressing tapered core, a self drilling apical end and a narrow coronal region.

Abstract: A dog toothbrush assembly has two plastic end caps with blind cavities that face one another and receive an elongated generally cylindrical chew element which is attractive to dogs such as an edible treat or other chewable material. The end caps are connected by screw fasteners to the support member of a brush, and an array of tufts of bristles project upwardly from the support member to engage the elongated chew element. The chew element is supported with respect to the bristles such that when a dog chews on the chew element the dog's teeth also encounter and are brushed by the bristles. When the chew element is worn or consumed, an end cap is removed by releasing one of the screw fasteners, thereby giving access for insertion of a replacement chew element.

Abstract: Orthodontic positioning devices, and related methods and systems, are disclosed for use with one or more orthodontic elastic members. The disclosed devices are configured to couple with an orthodontic elastic member so as to react a force from the elastic member into the appliance to, for example, generate traction forces on the patient's teeth to produce a desired occlusion. A positioning device includes a patient removable tooth positioning appliance having teeth receiving cavities shaped to receive and apply a resilient positioning force to a patient's teeth. The appliance includes a hook configured to interface with an orthodontic elastic member. The hook can be configured to be offset from a surface of a tooth when the appliance is coupled with the patient's teeth and no elastic member is coupled with the tooth. The hook can be curved so that the hook is more retentive on the aligner. The hook can be reinforced so that the reinforcement resists deformation when the elastic is in place.

Abstract: A headgear can be worn on a user's head to adjustably fix a mouthpiece inserted in an oral cavity. The headgear includes: a front pad brought into contact with and pressed against a front pressure point of an outer surface of the buccinator between the zygomatic bone and the mandible in the face region; one or more rear pads brought into contact with and pressed against one or more rear pressure points so that a resultant force becomes a reaction force paired with a pressing force of the front pad, in a region from the top to the back of the head; a frame fixing the front pad and the rear pads; a front horizontal bar fixed to the frame at a position in front of the lip region of the head; and an adjustment part installed on the front horizontal bar to mount the mouthpiece.

Specifically, a first integrated construct including a bridge disposed between the first lip holder and a second lip holder, and a second integrated construct including a tongue receiver defining an open-ended chamber and a tongue receiver support including a pair of arcuate support members each having an arcuate portion joining a support member first arm adapted to correspondingly releasably couple to the first lip holder and the second lip holder and a support member second arm correspondingly coupled to the tongue receiver.

Abstract: An improved preparation method uses an additional preparation tray as part of a multi-step tray alignment system which achieves orthodontic tooth movement. The preparation tray incorporates openings in the tray for the application of a bonding preparation fluid, such as an etching agent, or alternately, an etching and bonding agent, in the correct location and amount. The openings are at least the size and shape of the tooth attachments and greatly reduce the tooth surface area accessible to the clinician. This confines the bonding preparation fluid to an area equal to, or slightly larger than, the attachment contact area. The method and apparatus provide faster application, vastly reduced cleanup, less tooth enamel damage, and less chair time for the patient.
