A support for sustaining and/or forming a dental prosthesis, comprises an axle, an anchoring part which can be anchored in a bone or a master model, and a head part which protrudes out of said bone or master mode. The head part has intermediate spaces distributed around the axis, i.e., several first intermediate spaces forming a divided circle, and a second, wider and/or deeper intermediate space. A cap can be fixed to the support. The cap has at least one projecting part for engaging in an intermediate space and, optionally, can be configured for fixing in several different rotational positions or a single rotational position, the support allowing exact positioning. The cap can also be produced without a projecting part of the type mentioned. The same support can be used to form different types of dental prostheses.

Support for sustaining and/or forming a dental prosthesis

The device ( ) for holding and/or creating a dental prosthesis comprises an implant ( ) with an axis ( ) and with a metal main body ( ) which forms at least a large part of an anchoring part ( ) intended to be anchored in a bone ( ) and has an axial hole ( ). A ceramic body ( ) or covering is also connected nonreleasably and directly to the main body ( ). A metal metal &lsqb;sic&rsqb; bolt ( ) which can be secured in the hole ( ) of the main body ( ) protrudes into a blind hole ( ) of a ceramic body ( ) which is rigidly and nonreleasably secured on the bolt ( ) and covers the end of same directed away from the main body ( ), and if necessary can be ground after insertion into the mouth of a patient and permits rapid and simple impression-taking.

Device for holding and/or creating a dental prosthesis

The implant ( ) has an anchoring part ( ) with an axis ( ), a generally cylindrical section and a peripheral surface ( ). The latter is provided, in the generally cylindrical section, with protuberances ( ) which are distributed around the axis ( ). At least the majority of these protuberances are elongate and parallel with the axis ( ) and have at least one terminal surface which is contiguous with a recess ( ) having a base formed by the peripheral surface ( ). In this way, the anchoring part ( ) can be pushed into a substantially cylindrical hole ( ) in a bone ( ) such that the implant ( ) is immediately anchored in the bone ( ) in a stable manner, said implant nevertheless having a high degree of strength.

Implant for holding and/or forming a dental prosthesis or artificial finger joint

A device for forming a dental prosthesis includes a support and an element which can be attached thereto, such as an impression element. The support has an anchoring part for anchoring in a bone or a master model, a shoulder with an annular shoulder surface, and a head. The impression element has an elastically deformable fixing agent. When the device is assembled, the fixing agent jams and/or latches with the support, either externally on the support, on the side of the shoulder facing the anchoring part, or in an axial hole of the support. The element can be quickly detachably connected to the support by placing it on top of the support, and can be quickly separated from the support by moving the support away. When the device is assembled, the support and the element can lay on top of each other with annular surfaces. The annular surfaces have fully circular outer edges which are visible from the outside in an approximately radial viewing direction.

Device for forming a dental prosthesis

The case (,) comprises a receptacle (,) with two detachably interconnected receptacle parts (,). The receptacle (,) contains a dental implant (,) and a holder (,). The dental implant (,) has an anchoring section (,) designed to be anchored in a bone, i.e., an outside thread, and an outer section (,) indented to jut out from the bone. The holder (,) engages the outer section (,) of the dental implant (,) and detachably secures it using clamping and/or locking means (,). The dental implant (,) and the holder (,) are connected to each other by anti-rotation means (,) preventing rotations around a common axis (,). Once the case has been opened (,), the holder (,) can be gripped manually or using a tool or instrument and the dental implant (,) held by the holder (,) can be inserted into a bone in the mouth of a patient by screwing, pushing or pressing said implant into the bone.

Container holding a cartridge and a dental implant arranged therein

The invention relates to a dental implant which has an axis and a hole with a positioning section. Said positioning section has projecting parts and intermediate spaces distributed alternately, one after the other, along the periphery. Said intermediate spaces comprise several first intermediate spaces which create a division, and a second, wider intermediate space. A secondary and/or supplementary structural part can be attached in the implant, said part having a connecting section which extends into the hole. Said connecting section can have projecting parts for engaging in the intermediate spaces of the implant, and can be configured in such a way that it can be fixed to the implant in several different rotated positions or a single rotated position. The secondary and/or supplementary structural part can also be produced without projecting parts of the type mentioned, so that it can be screwed into the implant.

Dental implant and device with a dental implant

With the invention a mounting system is shown for metallic support shells at implantable joints with pin-like metallic anchoring elements. The anchoring elements have a head which lies on a shoulder of the implant in the axial direction. Between the shoulder and the head there is a circular sealing edge. A contact pressure force is produced on the head by a contact pressure generating screw which is so great that a metallic seal is produced through plastic flow at the scaling edge which is liquid-tight and prevents the intrusion of abraded particles from the inner region of the support shell.

Device for connecting a dental implant to a conical secondary element

The device (1) for forming a dental prosthesis has at least one support (3) with a base (4) which in the use of the device (1) is inserted into a jawbone (13) of a patient or into a jaw model. The support (3) has a conical bearing surface (4n) and also a shoulder (7e) which faces the base (4) and for example is formed by a flank of an annular groove (7d). The device (1) has for the or each support (3) a cap (8) which bears with a conical countersurface (8f) on the conical bearing surface (4n) of the support (44) when the device (1) has been assembled. The cap (8) has a hole (8k) with an internal thread (8m) and with an axis (11) which forms an angle with the axis (10) of the two conical surfaces (4n, 8f). A screw (9) screwed into the hole (8k) engages with a tapering end section (9b) on the outer border (7f) of the shoulder (7e) and thus presses the countersurface (8f) against the bearing surface (4n). The end section (8b) of the cap (8) facing away from the base (4) is hole-free and therefore makes possible favourable and aesthetic shaping of the cap (8).

Device for forming a dental prosthesis and method of manufacturing such

The universal joint prosthesis has a cap which has an outer shell, an inner shell, a calotte-shaped, smooth outer surface formed by the outer shell and an inner surface formed by the inner shell and having projections distributed along the circumference. At least some projections have undercuts and/or are provided with through holes. The outer material forming the outer shell has, with the same surface characteristics, a smaller coefficient of friction than the inner material forming the inner shell. On the other hand, the inner material permits a firmer bond with a bone than the outer material. The universal joint prosthesis also has perforated sleeves projecting from the cap. The universal joint prothesis can usually be attached firmly to a bone without a binder, the undercuts and/or holes helping to provide a permanent connection between the cap and the bone.

Universal joint prosthesis

The device for fixing a dental prosthesis has a base which can be inserted into a jaw bone, an abutment and a shell. The base has a hole with a mouth at its end face, with an internal thread and with an extension and has a conical annular surface enclosing the mouth of the hole. The abutment has a thread part which passes through the shell in the assembled device and is screwed into the internal thread of the base, and an outer part located outside the base and serving for holding a dental prosthesis. In the assembled device, the shell fits into the extension of the hole and rests with a conical outer surface firmly against a conical inner surface of the base. Furthermore, the outer part of the abutment rests with a conical stop surface firmly against the annular surface of the base. In the assembled device, the abutment is connected to the base in a stable manner and covers its end face without leaving gaps.

Device-for fixing a dental prosthesis to a jaw bone

A means for fastening a capping on bone tissue or the like over an area of original, locally depressed, chipped or fractured tissue to promote the growth of additional tissue is disclosed, comprising generally, a pin which has, at one end, a bead for attachment of a foil and, at the other end, an external thread for threading into the original tissue or bone. Between the bead and the thread is a smooth-walled segment whose diameter is preferably larger than the diameter of the external thread. The method, unlike previous prior art methods, facilitates growing of the bone between two teeth or between teeth and a denture. The method permits, for example, restoring a jawbone to a larger extent than over areas where there were only slight depressions.

The device comprises a tool 21 with a cutting part 23 and a shaft 25. The shaft 25 is provided with an annular catch groove 25d and carries a sleeve 31 which encloses it and comprises a catch projection 31c which engages in the catch groove 25d so as to be detachable, wherein the shaft 25 and the sleeve 31 are rotatable relative to one another. The sleeve 31 is provided with a coolant inlet 31d which opens into an annular duct 41 enclosing the shaft 25 and communicating with a passage 43. This duct 41 is connected with the passage 43 for guiding a coolant, which passage 43 extends through the tool 21 until its cutting part 23 and opens into the surroundings at the free end of the cutting part 23 or in the vicinity of the latter. The sleeve 31 can be secured against axial displacements by means of a catch projection 31c, which is engaged in a catch groove 25d, without separate connection parts and without taking up much axial space.
