The internal cavity comprises an interlock chamber having a depth measured from the top surface equal to a first distance. The interlock chamber comprising a cylindrical portion and plurality of semi-circular channels arranged around a periphery of the cylindrical portion. A threaded chamber that includes threads is located below the post-receiving chamber. The cylindrical portion has a first radius and the channels have a second radius, a ratio of the first radius to the second radius being between approximately 4:1. and 2:1.

Abstract: An arrangement and an implant are provided for increasing the stress resistance of the implant arranged in an upper jaw bone. The implant has access via parts to the sinus cavity. At said parts, the implant is arranged with a convex or rounded front surface which, upon access, lifts the sinus mucous membrane, without piercing the latter, and thus forms a closed space between the parts and the underside of the mucous membrane. The implant is provided, at least at said parts, with growth-stimulating substance or substances which interact with cell-containing body fluid which penetrates or has penetrated into the space, so that new bone is formed around said parts of the implant.

Abstract: An implant and a method of producing the implant are provided. The implant can have at least one outer surface extending in its longitudinal direction. The implant can comprise an underlying wave pattern, an intermediate wave pattern, and a microscopic roughening layer. The underlying wave pattern can have waves that extend substantially in the longitudinal direction. Further, the intermediate wave pattern can be formed on the waves of the underlying wave pattern. Additionally, the microscopic roughening layer can be formed on top of the underlying wave pattern.

Abstract: The present application relates to a fitting for insertion into a dental implant in an insertion orientation defining a central insertion axis (X) and an insertion direction (D) of the fitting. The fitting comprises at least one resilient spring member being expandable perpendicularly to the insertion axis (X) of the fitting for impeding a movement of the fitting relative to the dental implant along the insertion axis (X) when inserted into the dental implant. It further comprises an alignment feature for rotationally aligning the fitting relative to the dental implant about the insertion axis (X). The fitting is characterized in that the alignment feature extends further in the insertion direction (D) than the spring member.

Abstract: To anchor a fixture in a jaw bone, the fixture is applied in a hole which is substantially smaller than the diameter of the fixture. The fixture has a front portion which from the point of view of diameter grows very much narrower and which is arranged with both a cutting function and a threading function. The fixture is provided with a thread, with one, two or more thread turns extending down along the greatly narrowing portion while substantially maintaining their thread profile. One or more porous layers arranged on the thread turns can also be included. In this way the fixture can exploit the clamping effect from the soft parts of the jaw bone and still effectively penetrate through any hard parts possibly present in the jaw bone, without these hard parts being pressed inward upon fixture application. An effective fusion of the fixture in the jaw bone is achieved with the aid of said porous outer layers.

Abstract: Methods, systems, and computer-readable media are disclosed herein for virtually planning a cranial guided surgery in a subject. These include, in some embodiments, generating a first data set based on input data obtained of a physical reference structure having a defined fixed relation to a bone structure of said subject and generating a second data set based on input data obtained of a master structure for a surgical template, where the master structure has a defined relation to said physical reference structure. Further, in some embodiments, a third data set for production of said surgical template can be generated based on the first data set and the second data set, wherein the relation of said physical reference structure to said master structure is preserved.

Abstract: A surface structure is produced on an outer surface of an implant or a fixture and forms a base structure in a range of implants related to different types and qualities of jaw bone. During production of the surface, parts of a turning tool are placed against the implant or against a blank which is intended to form the implant. The parts and/or the implant are assigned controls which give rise to mutual displacements between the parts and the implant so that the parts follow a substantially spiral trajectory along the outer surface. By means of said controls, a long wave pattern is formed with successive peaks and with through lying between these. In this connection, a through can be arranged adjacent to the outer parts of an existing thread. The controls are chosen so as to produce through depths in the range of 25 to 250 ?m, preferably 50 to 200 ?m. The invention also relates to an implant which has the same character as the implant produced by the method.

Abstract: The present invention relates to a method of attaching a dental component having an angulated screw channel to a dental implant. The present invention also relates to a dental component having an angulated screw channel and a metal adapter.

Abstract: An implant (5, 13) and/or a unit (9), e.g. spacer sleeve, belonging to said implant is/are intended to extend through a hole (4?) formed in a jaw bone (2) and through soft tissue (3) belonging to the jaw bone and to comprise one or more outer layers of principally titanium dioxide. Each layer consists of crystalline titanium dioxide which largely or completely assumes the anatase phase. The invention also relates to a method for production of such a dental implant (5, 13) and/or of a unit (9) belonging to it, which has one or more outer layers of titanium dioxide. The method is an anodic oxidation method in which the part or parts bearing the outer layer(s) is/are applied to electrolyte under voltage, e.g. comprising sulfuric acid and phosphoric acid, and the voltage (U) and the dwell time of the part or parts in the electrolyte are chosen such that titanium dioxide, largely or completely assuming the crystalline anatase phase, is formed.

Abstract: An implant (10) has one or more surfaces (10a, 10b) with a basic or starting surface structure (1a) derived from mechanical working. A topographic modification of the surface structures is arranged on said surface structure or surface structures. The topographic modification can be formed, for example, by means of shot-peening, etching, plasma spraying, chemical action, etc. The topographically modified surface structures support bone-growth-stimulating agent. In a method for producing the implant, three subsidiary methods are used for carrying out the mechanical working, the topographical modification, and the application of the bone-growth-stimulating agent. An important niche in the demand which exists in the field of implants is thus covered in an advantageous manner.
