Abstract: A dental implant is provided having a longitudinal axis, and comprising an elongate body portion at an apical portion of the implant and a neck portion at a coronal portion of the implant. A first helical thread profile is around a first portion of the elongate body, at the apical portion. A second helical thread profile that is different from the first helical thread profile, is around a second portion of the elongate body that is between the first portion and the neck portion. The implant further comprises a third helical thread profile that is around the neck portion and that is different from both the first and second helical thread profiles. Other applications are also described.

Abstract: The invention relates to an implant analog for placing in a jaw model for modeling a dental prosthesis by means of the jaw model. Said analog comprises a sleeve extending in an axial direction and comprising an axial inner bore having an internal thread for threading in a fastening screw for fastening a post to the implant analog, wherein the post is provided for fastening a dental prosthesis. According to the invention, the sleeve comprises a self-tapping external thread for threading in the implant analog into a jaw model. The invention further relates to a method for applying such implant analogs and an implant system having such implant analogs.

Abstract: The invention relates to an occlusion template having position markers comprising prescribed dimensions, applied to prescribed locations of the template, and recognizable as position marks on an image of the jaw or a jaw area of a patient. In order to be able to analyze locally limited X-ray images, the invention proposes that the template comprises more than three position markers, each disposed in the bite area of the template.

Abstract: There are provided a system and a method for assisting a user in preparing a dental implant surgery which includes a prosthesis installation. The system and the method provide a dental implant surgery plan for the user and generate a list of all items required for the dental implant surgery. The items of the list comprise a dental surgical guide, at least one implant and components for at least one prosthesis. The system and the method use a record of suppliers for the items of the list and, for each item of the list, propose to the user a supplier selected among the suppliers of the record. The system and method then allow the user to order all items of the list, which are shipped to the user for the surgery.

Abstract: The invention relates to a machining device, especially for producing a drilling jig for dental implants. The tool can be displaced along three translational axes and can be swiveled about two swiveling axes. The displacement device for the tool comprises a C frame which can be displaced along two horizontal translational axes.

Abstract: The invention relates to a positioning cylinder for a surgical drill, which positioning cylinder is screwed into a drilling jig by means of an external thread, especially for drilling in a jawbone for a dental implant. The positioning cylinder comprises a cylinder base having an axial internal bore and an external thread for screwing it into the drilling jig. The positioning cylinder is designed as a one-piece or integral part and the internal bore is used to guide the drill. The invention further relates to a system consisting of said positioning cylinders and surgical drills.

Abstract: The description, among other things, concerns a Surgical Tool for the preparation of bones, comprising a tool shank, designed to be inserted into a rotatable tool holder and having a duct for conducting the flow of a cooling or rinsing fluid, a machining part driven by the tool shank and rotatable around an axial rotation axis and placed at the proximal axial end of the tool shank, a guide element extending in axial direction of the Surgical Tool, placed at the proximal axial end of the machining part, axially movable relative to the machining part and designed for insertion into a pilot drilling, having at its surface one or several rinsing slots extending in axial direction for conducting the cooling or rinsing fluid, wherein the Surgical Tool and the rinsing slots are designed in such a manner that the exit point at which the cooling or rinsing fluid exits the duct into the rinsing slots, is placed in the area of the passage between the proximal axial end of the machining part and a distal axial area of th

Abstract: A dental implant includes a body having a coronal end, and an apical end opposite the coronal end. An implant-prosthetic interface region is provided adjacent the coronal end. A tapered region is adjacent the apical end. A variable profile helical thread extends along the tapered region. The thread includes an apical side, a coronal side and a width defined between the apical and coronal sides. The variable profile thread includes an expanding width in the direction of the coronal end.
