摘要： An arrangement comprising a spacer element (1) which can be fastened in an implant with a first screw (3) which can be acted on by means of a screwdriver which can be introduced into the head of the first screw via a first passage (2) arranged in the spacer element. The spacer element is designed to support a superstructure which can be fastened to the spacer element with a second screw (6) which can be acted on by means of said screwdriver, or a second screwdriver which can be introduced into the head of the second screw via a second passage arranged in the superstructure for screwing the second screw into a thread in the spacer element. The first and second passages are each arranged with their centre line at an angle in relation to the direction of screwing of the respective screw and thus set the respective screwdriver at an angle relative to said direction(s) of screwing when the screwdriver is applied via its front parts into the respective screw head and the respective screw is tightened in its associated thread.

摘要： An implant comprises or consists of titanium and has one or more surfaces which can be applied in or on a bone growth area. One or more of the said surfaces are arranged with a depot for bone-growth-initiating or bone-growth-stimulating substance, which depot is formed by a pore arrangement in a relatively thick oxide layer on the titanium. The substance is acted on, for a considerable period of time, by one or more release functions for the substance which permit a controlled or optimized release of substance to the surrounding tissue or bone growth area.

摘要： The present invention relates to a method for making artificial tooth bridges consisting of a ceramic densely sintered high strength individual core veneered with Porcelain using powder metallurgical methods. According to the method the individual densely sintered bridge parts are joined together to a bridge core by a particle reinforced glass. Since only the glass material wets the surface of the densely sintered parts, the glass is the binding material that holds the core together and the particles function to only increase the strength (i.e. Kc value) of the bulk glass material.

摘要： The invention relates to a coated dental screw (14) for retaining and securing components (12, 16) of a dental prosthetic implant stack (10). The screw (14) is coated with a hard carbon coating/film (20) to provide a low friction surface finish which advantageously results in improved preloading of the screw (14), and hence a high clamping force between the components (12, 16) of the dental prosthetic implant stack (10). The coating (20) can comprise diamond-like carbon (DLC), amorphous diamond, crystalline diamond, or a combination thereof. Other advantages provided by the hard carbon coating (20) include high mechanical surface hardness, biocompatibility, corrosion resistance, chemical inertness and low cost.

摘要： A guide device is able to interact with a number of sleeves disposed in a tooth template. The guide device includes a guide part which can be fitted to a corresponding sleeve and which is connected to or forms part of a handle part for fitting to the corresponding sleeve of the guide part. The latter is disposed with a ball bearing race and the handle part includes or interacts with an actuation part which is able to interact with the ball bearing race, and by means of which different relative positions between the handle part and the guide part are lockably set up. The invention provides outstanding adjustability between the handle part and the guide part in different positions for the teeth and spaces which are to be treated.

摘要： In an arrangement for recreating a model, use is made of an original model (1) of implant and/or tooth remnants (2-5) in a system for producing a dental construction (32). The system includes a reading apparatus (10, 13) and a first levelling function (6). A reproduction of all or part of the original model is created in CAD equipment. The said dental construction is created in the CAD equipment, and the reproduction and the construction are divided up into parts whose axes of inclination and contact surfaces are identified in terms of position and direction. Replicas of the implant and/or tooth remnant parts and the construction parts are produced and mounted on a mounting member (23) after bore holes for the replicas of the tooth remnant parts have been established using boring equipment. The said bore holes are estabished by means of a second levelling function and the bore holes receive positions and longitudinal axis inclinations which correspond to the positions and the inclinations of corresponding axes in the original model. The replicas for the tooth remnant parts can be fixed in terms of angle of rotation in the mounting member with position-fixing members (identification members). The last-mentioned replicas form the recreated model on which the construction replicas can be applied.

摘要： In connection with implants for bone or tissue, delivery of bioactive substances to the bone or tissue is ensured. The implant is designed with an internal space, and one or more bodies comprising the bioactive substance are designed to cooperate with the bone and/or tissue structure surrounding the implant and to release the bioactive substance to the said structure. The said body or bodies is/are applied in the space in order thereby to be exposed to the surrounding structure and deliver the bioactive substance or substances to the latter.

摘要： A system comprises a computer appliance (7) designed to receive, and to present on screen, first information (12) transmitted from identification equipment (6) and based on detection of a jaw bone structure. Modification information which can be introduced into the computer appliance shows a visual dental bridge structure applied on the jaw bone structure with associated teeth and dentine. Orientations for implants are also shown. The computer appliance produces a CAD file which is based on the first information and the modification information. The file is received in a stereolithography machine which issues second information which can be processed in the equipment (9) for production of the physical template with associated through-bores for sleeves which determine recessed positions and directions for the implants. A working model (16) is produced with the aid of the physical template which is also used for hole formation in the jaw bone structure. The invention also relates to an arrangement of a template produced by stereolithography and by means of information from the computer appliance. By means of the invention, the installation of the dental bridge on the patient can be increased at lower cost, with shorter times and a sustained degree of accuracy.

摘要： A substrate has or is provided on a surface with a first porosity. A dispersion with low-viscosity liquid is applied to the surface in order to form a ceramic layer with a second porosity having preferably larger and/or more pores than in the first porosity. The liquid has the ability to be sucked by capillary force into the first pore formation and, in a first stage, to retain on the surface material and/or liquid particles which do not penetrate into this first pore formation, and which contribute to the continued construction of the layer. In a second stage, the substrate is subjected to sintering in which the particles finally forming the layer are held together with intermediate spaces which consist of or are included in the second porosity, the spaces being formed either by the fact that material and liquid particles separate from the particles finally forming the layer are driven off during the sintering and/or by the fact that the particles forming the layer are chosen with a particle size which means that the last-mentioned particles are held together after the sintering despite the intermediate spaces. The invention also relates to an arrangement. By means of the invention, a dental product can be provided with excellent porosity which is advantageous in connection with dental installations.
