摘要： A supporting part (28) for a denture (21) will be produced in one piece, or in two or more partial pieces which are assembled. Surface-reading members (22) are in this case used for forming digital representations (23) which are supplied to computer equipment, by means of which machining information items (25) are generated. The supporting part original is produced with the aid of working models, and a blank is applied in holders which can be applied in a machining device which is controlled by the machining information. Electro-erosion tools are created with the impression model/working model. The tools include electro-erosion electrodes at positions for the dummies for the implants or their spacing members. Using the electro-erosion equipment, the machined blank is provided with recesses for bridge parts which are to bear against the implants or their spacing members. The contact surfaces on the bridge parts and the connection surfaces on the implants bear against each other with great precision, and the inclinations of the bridge parts coincide with the inclinations of the implants or are slightly displaced in parallel with respect to the latter.

摘要： The present invention relates to a method of manufacturing artificial tooth veneer restorations for natural teeth composed of a ceramic core (B) by pressing and sintering ceramic powder. The core (B) is preferably manufactured from a high strength densely sintered ceramic material by copy milling from an impression of the prepared tooth surface (P) to a compacted body, a presintered body or a sintered body. Alternatively the core (B) is manufactured by compacting the ceramic powder against a body, which surface is copy milled from a modell of the prepared tooth surface (P). During the copy milling the sintering shrinkage is considered by enlargement of the copy milled compacted body, the presintered body or the sintered body corresponding to the sintering shrinkage. The tooth veneer restorations are given their final shape by shaping the external surface (Y) of the compacted, presintered or sintered ceramic body. After the final sintering the external surface (Y) can be shaped before a veneer material is attached to the external surface of the core (B) by firing of dental porcelain (A). Manufacturing ceramic teeth veneer restorations according to the method of this invention increases their strength and accuracy to shape.

摘要： A sensing device senses a contour (3a) of a model (3) and generates, in response to the sensing, a representation (i1). The representation is used to control tool equipment for producing, for example, dental implants, support members, etc. or tools for producing such implants, members, etc. The representation (i1) is fed to computer equipment (23) which generates a signal array (i13). This latter effectuates or is included in the control of the tool equipment. The signal array (i13) is selected or compressed so that it will be sufficient to enable the tool equipment to perform with its expected degree of accuracy/tolerance in production.

摘要： The disclosure relates to a method for producing oral and extraoral prosthetic constructions of composite material with considerable fibre content, and in particular to the production of jawbone anchored dental bridges of reinforced plastic. A number of mutually retracted tubularly braided fibres (1), possibly in combination with continuous fibre strands, so-called roving, together constitute a fibre system which is packed in a tube, hose (2) or the like which is sealed and serves as outer packaging. A suitable matrix material, for example acrylic plastic, is injected into the hose for impregnation (wetting) of the enclosed fibre system, whereafter the hose (2) is removed. The fibre system is then polymerized to form a finished prosthesis blank in a mould. The prosthesis blank is then given suitable form and appearance by conventional after treatment.

摘要： A ceramic unit for replacing lost substance or tissue and having a contour transferred from a preparation model or a replacement position is made of densely sintered ceramic material. The model contour in question or a corresponding contour is transferred in a linearly enlarged state to a part (4) belonging to a press tool (6), whose enlarged contour (2′) defines a mould cavity (5) formed by means of the part in the press tool. Ceramic starting material is applied in the mould cavity and is subjected to compressive force. The unit produced in this way is released or removed and is treated in one or more sintering procedures in which it is subjected to linear shrinkage until the contour defined by the tool part has essentially the same size as the model contour.
It is proposed that Figure 2 accompany the abstract.

摘要： In the joining of two elements (10, 11) of hard material which are included in an implant structure or prosthetic structure, the elements are disposed towards one another by means of a joint (34) formed by contact surfaces. The elements are adjusted to one another and mutually fixed and welded together by laser equipment (13). Registering circumferential portions of the joint are exposed to two focusing optical devices (14, 15) which emit laser pulses or laser beams for the welding and form part of the laser equipment. The devices are aligned each towards one of two substantially registering, or slightly mutually offset, starting areas. Each respective area includes a section of each respective joint circumferential portion with circumjacent parts on the elements. The laser equipment is energized to emit, via the devices (14, 15), simultaneous or alternating laser pulses or laser beams, and the elements and devices are mutually influenced in respect of their movements such that laser output emission may be effected towards the starting areas and subsequent areas with associated sections of joint circumferential portions and material parts. By such means, a distortion-free joining will be attained.

摘要： The invention relates to a spacing member for a tooth implant, comprising a base portion (1) for attachment to a fixture (22) implanted in the jawbone, and an upper part (9) with an essentially conical limit surface for attachment to a tooth prosthesis. The base portion comprises a through hole (5) for a spacing screw (6) which is intended to engage with an internally threaded bore (23) in the upper portion of the fixture and thereby form a first screw connection for locking the spacing member securely in a defined direction of deflection in relation to the fixture. The upper part (9) comprises a second screw connection for attachment of the tooth prosthesis, which screw connection forms a fixed angle δ in relation to the first screw connection. The upper part (14) of the inlet opening (13) for the through hole (5) which is formed in the conical limit surface in the upper part (9) of the spacing member, and through which opening the spacing screw (6) is intended to be introduced during assembly, is offset towards the line of symmetry (1a) of the through hole. In this way the height of the spacer can be kept low, even in those cases where the fixed angle δ between the two screw connections is comparatively small, preferably within the range of 15 - 25°.
