Abstract: An arrangement and an implant are provided for increasing the stress resistance of the implant arranged in an upper jaw bone (1). The implant has access via parts (9, 4?) to the sinus cavity (5). 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 (7) 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 (15) which interact with cell-containing body fluid (8) which penetrates or has penetrated into the space, so that new bone (11) is formed around said parts of the implant.

Abstract: A dental replacement component Is to be able to be produced with a color which better matches the area surrounding the component. The component has a reinforcing element (4, 17) which comprises carbon fiber wires arranged in one or more carbon fiber hoses. These carbon fiber wires can be held together by means of hardenable substance so as to form a homogeneous part of the reinforcing element. At least that portion or those portions of the reinforcing element directed toward the surrounding area supports/support or is/are provided with additional fiber material with a color which better matches said color than does the carbon fiber. The invention also relates to a system for producing such a replacement component. Besides the more advantageous coloring of the reinforcing element, the latter is able to retain its physical properties in respect of its strength.

Abstract: A device for determining the position of a sleeve, on the one hand in the vertical direction in relation to a fixture dummy in or on a model of a bone, and on the other hand in the transverse direction in relation to the longitudinal axis of the fixture dummy. An expansion spacer cooperates with the fixture dummy and the sleeve. An expansion screw is designed in such a way that, when acted upon, it in turn acts upon the expansion spacer so that the latter determined the position of the sleeve and thus of the template relative to the jaw bone and the fixture.

Abstract: Two or more implants (8, 9, 10) are arranged in succession in the jaw bone (1) and bear or comprise growth-stimulating substances (25), here called GSS, which, as a function of secretion of body fluid at the implants, are intended to be released and form new bone (11-15) around the implants. The implants are designed to work with a release process for GSS, permitting a leveling-out effect along the extent of the jaw bone in the horizontal and/or vertical direction and/or a level-raising effect in the vertical direction. In this way it is possible to achieve optimum positions for the implants without the risk of reduced stability and/or compromised esthetics.

Abstract: 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.

Abstract: An arrangement for producing at least a part of a dental product including an interface configured to receive and transmit ordering and manufacturing data from a plurality of users of different dental treatment systems.

The guide part can be connectable to the supporting part with the guide part being operative to align a tool for use in the dental treatment.

Abstract: In a method and arrangement for allocating prosthetic installation work between at least three parties (A, B, C) a dental situation and fixture application are simulated on a computer screen by the first party. The second party produces first components in connection with the prosthetic installation with the aid of a recording and said simulation. Second components are supplied by the third party (C) and the prosthetic installation is assembled and fitted by the first party by means of said first and second components. The recording includes first and second readings of a loose prosthesis and a portion supporting the prosthetic insallation. The simulation includes collation of representations of the readings on a computer screen. Simulated fixture applications are constructed and a model is produced by one of said parties, or a fourth party. An assembly template guides hole-forming members in an actual substrate in directions which correspond to the directions of the fixtures.

Abstract: In an arrangement with implant and attachment part/dental bridge, the latter comprises one or more recessed walls. The implant is designed or can cooperate with a portion which can be arranged on a spacer sleeve belonging to the implant and extends substantially parallel to the recessed wall. The attachment part and its respective recessed wall is arranged with displaceability in the main longitudinal direction of the implant relative to the outer surface of the portion. The portion is arranged to be expandable so that, in a given position of longitudinal displacement, it is possible to achieve interaction between outer surfaces of the portion and the recessed wall and thus anchoring of the attachment part to the portion or the implant. The invention also relates to a device with two or more implants and dental bridge. By means of the invention, discrepancies between dental bridge and the implants can be taken up in an effective and rapid securing principle.

Abstract: 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.

Abstract: A manufacturing system for dental products (P, P?) operates with coordinating units (9) which receive and register orders from customers (1, 2 and 3). The coordinating units distribute the order to production units (11, 12 and 13). The various units include database whose contents are updated by data replications in conjunction with changes to system functions, system application, system structure, etc. The data contained in the databases of the production units are entered in memory elements which are arranged for accessing program contents when executing data replications via one or more interfaces via which the function for data replications in the system has access or is effected.

Abstract: The invention relates to a fixture for orthodontic and osseo distraction of the alveolar process, and for the stabilization of temporary prostheses. The fixture has an external threading, compromising a treaded part for insertion into a prepared site in the jawbone, and a treaded part, to which pressure may be applied by means of an internally threaded element e.g. a nut, when used in conjunction with an appliance supported by teeth or adjacent static fixtures.

Abstract: A system useful in producing a three-dimensional body comprising bone or tissue-compatible material includes a detection and analysis site which identifies and simulates a portion of a body in connection with an implantation situation. A production device produces a model responsive to the simulation information. A flame-spraying apparatus provides the bone-compatible and/or tissue-compatible material in a powder form through a nozzle. Relative movement between the nozzle and a support member supporting the model or die is controlled to apply one or more layers of the bone-compatible material to the model. A method includes using a computer to identify and simulate a body in connection with a given implantation situation, and producing a model or die accordingly. the bone or tissue-compatible material is flame-sprayed in a powder form. Movements of a nozzle and/or a supporting member are controlled so as to effect a desired surface characteristic on the three-dimensional body.

Abstract: Two or more implants (8, 9, 10) are arranged in succession in the jaw bone (1) and bear or comprise growth-stimulating substances (25), here called GSS, which, as a function of secretion of body fluid at the implants, are intended to be released and form new bone (11-15) around the implants. The implants are designed to work with a release process for GSS, permitting a leveling-out effect along the extent of the jaw bone in the horizontal and/or vertical direction and/or a level-raising effect in the vertical direction. In this way it is possible to achieve optimum positions for the implants without the risk of reduced stability and/or compromised esthetics.

Abstract: An implant (1) has attachment and hole-insert parts (2, 3) with an outer surface or outer surfaces having external layer arrangements (6, 7). The implant can be provided in a known manner with threads (3a, 3b) on cylindrical and conical portions. The implant is made in principle in two production stages. In a first production stage, the outer surface or outer surfaces (6a) of the implant are given a relatively high roughness value and/or a relatively high degree of porosity. In a second stage, the uneven or porous surface thus obtained is coated with an oxide layer (7) which can be uniform or can have different thicknesses along the longitudinal and/or circumferential directions(s) of the implant. In one embodiment, the oxide layer (7) can be coated with a bone-growth agent or bone-growth-promoting agent and/or calcium phosphate (16), for example by means of chemical deposition, dipping or sputtering.

Abstract: In an arrangement and method, use is made of a container for preserving, even for a long time, the new-bone-forming effect of growth-stimulating substances (GS) applied to one or more implant products. The container is arranged so as, dependent on being acted upon, to allow accessibility of the product concerned with applied GS as the time of its use. The container is arranged to enclose the product or the products with applied GS in an environment which is essentially free from air, water and moisture. The container functions as a vacuum container, and the storage times for GS can be extended considerably in relation to previously used arrangements and methods.

Abstract: A self-tapping implant for use in a jawbone includes a body with plural thread spirals arranged thereon; a conically tapering portion arranged at a front end of the body and having one or more bone-chip recesses therein which accommodate bone material cut off during a tapping operation. The bone-chip recesses are formed by removal of material from the plural thread spirals and body. At least in the conically tapering portion, the plural thread spirals are materially reduced, and each of the materially reduced threads have a cutting edge which extends inward from an outer edge of a respective remaining thread part. Each cutting edge of a number of associated cutting edges of the materially reduced threads have a pointed shape which, in a cross section thereof, essentially follows a line which deviates from a first radius through a point of the pointed shape of the respective remaining thread part.

Abstract: The invention relates to a preparation for restoring bone in the body of humans or animals in connection with an existing structure, a bone implant or some other prosthetic construction, as well as a method for restoring bone. The bone restoring preparation consists of an easily handleable and controllable preparation (composition) of resorbable calcium phosphate granules and a carrier of a biopolymer or lipid type. The preparation is intended to be applied in the position where the bone needs to be replaced, reinforced or built up, especially in connection with a bone implant or some other prosthetic construction where there is a lack of sufficient bone volume, or where the quality of the bone is too poor to allow a load-carrying function, for example permanent fixing of an implant.

Abstract: With the aid of bioactive or osteoinductive substances (10), a bone-based lateral support is built up for an implant (6) arranged in an assigned jaw bone hole in jaw bone (2) which extends defectively or irregularly. The implant is arranged so that it can be completely or partially covered by soft tissue, and possibly periosteum, or by a unit applied to the jaw bone and/or the implant. One or more spaces can in this way be formed on the lateral surface of the implant. Body fluid penetrates from or via the jaw bone and optionally the periosteum into the respective space. The osteoinductive or bioactive substances consist of matrix molecules, growth factors and differentiation factors and/or peptides with growth-stimulating properties, all called GSS, arranged in or the implant. Body fluid with cells is secreted and said GSS is released during an incorporation stage and forms, by interaction, new bone for said bone-based lateral support.

Abstract: An implant bears growth-stimulating substance(s), here called GSS, which can be released when the implant is arranged in a jaw bone hole. The release takes place in interaction with secreted, cell-containing body fluid so as to form new bone alongside the implant. The implant is arranged with an outer surface which can comprise the outer parts of a thread or can consist of bearing surfaces parallel to the inner wall of the jaw bone hole. First portions of the outer surface have first diameters or radii, and second portions have second diameters or radii smaller than the first diameters or radii. The implant bears against or cooperates with the hole wall via the first portions and, by means of the second portions and together with the hole wall, forms one or more closed spaces into which body fluid can penetrate and GSS can be released. The implant can alternatively be designed with a shape or shapes substantially corresponding to the tooth root configuration(s).
