Abstract: An implant is provided with an upper portion in which an internal socket extends. The implant can be tightened by a turning instrument which has first lateral surfaces that can cooperate with corresponding second lateral surfaces in the internal socket. One or more of the first and/or second lateral surfaces is/are arranged completely or partially with friction-enhancing means. The implant and the tool are arranged with interacting parts which extend beyond the first and second lateral surfaces and completely or substantially take up bending moments which act in or on said portion or are directed toward said portion and occur in the event of skewing, or a tendency toward skewing, between the implant and the tool. The arrangement counteracts mechanical stresses in said portion, the latter being able to retain its original shape even in the case of implants with small dimensions.

Abstract: Embodiments are provided for tracking teeth movement correction. One method embodiment includes using a set of positioning appliances shaped to move teeth through a number of successive stages of arrangements of an expected teeth arrangement model where each stage corresponds to a particular positioning appliance, mapping a current teeth position based upon positions of a number of physical markers attached to a number of physical teeth, comparing the positions of the number of physical markers with a corresponding number of virtual markers positioned on a number of virtual teeth of a stage in the expected teeth arrangement model, determining whether midcourse correction is needed.

Abstract: Intraoral phototherapy devices receive light from an associated light source and propagate the light into an oral cavity of a patient. The device comprises a light guide that receives light from an external light source. The light guide comprises a main body portion made of an optically transparent soft flexible biocompatible polymeric material sized and shaped to conform to contours of the oral cavity when inserted therein to direct the light to targeted regions of the oral cavity. The main body portion comprises a pair of spaced apart side wings sized and shaped to be received between a patient's teeth and cheeks on opposite sides of the oral cavity and a center flap intermediate the side wings for transmitting and directing the light to targeted regions of the oral cavity. A controller delivers light to the light guide in a controlled manner.

Abstract: An improved rotary endodontic file includes a multi-planar pre-curved apical portion having a first and a second curvature. The pre-curved apical portion begins at about one-third to one-quarter of the working length as measured from the tip end of the endodontic instrument. The first and second curvature permit the file to continually search and engage the walls of a tooth root canal in a forced inside-forced outside manner. As the file works its way down, it breaks free of any ledges encountered, probes lateral- and delta-type openings, and does not allow the file to stray from the curvature of the canal.

Abstract: A bite registration device is provided that can be placed within a patient's mouth and adjusted to a desired position relative to the patient's maxillary and/or mandibular teeth while permitting visual inspection of the patient's anterior teeth during acquisition of the bite registration. The bite registration device is also configured to permit introduction of bite registration material without having to remove the device from the patient's mouth once optimal positioning has been established.

The work section contains one or more continuous, spiral-shaped further channels. The first channel and the further channels open into a common chamber connecting the shank and the work section. The shank is sintered with the work section in order to form a one-piece, sintered component that encloses the chamber connecting the shank and the work section.

Abstract: A visualization apparatus and a system for enhancing hand-eye coordination during a medical procedure are provided. The visualization apparatus includes an elongate support member, a head member, an operating head element, and a processor. The head member connected to the elongate support member at a predetermined angle includes an angled wall for mounting a reflector. The operating head element connected to an upper end of the head member mounts and supports an objective lens. The objective lens focuses light from an operating field to a reflector to create an image of the operating field. An eyepiece lens accommodated in the elongate support member or the head member magnifies the created image. The processor operatively communicating with an image receiver processes and transmits the magnified image to a viewer. The orientation of the magnified image on the viewer is similar to the orientation of the operating field, thereby enhancing hand-eye coordination.
