A system for dental restorations may comprise an abutment comprising an implant engaging portion and a component supporting portion terminating in a coronal end of the abutment. The implant engaging portion may extend apically from the component supporting portion and may have an external surface feature configured to be received in mating engagement within an opening in a dental implant. The component supporting portion may comprise at least one first snap-fit retention feature disposed on an outer peripheral surface of the component supporting portion. The system may further comprise a temporary coping made from a material that permits chemical bonding of the temporary coping with a veneering material of a temporary tooth restoration. The temporary coping may comprise at least one second snap-fit retention feature configured for snap-fit engagement with the at least one first snap-fit retention feature of the abutment.

The present disclosure provides an artificial tooth root for implantation of an artificial tooth. The artificial tooth root may include one or more body portions having a cylindrical shape, and an extension portion coupled to at least a portion of a lower portion of each of the one or more body portions and extending from a lower side and a side of the one or more body portions. The above body portions of the artificial tooth root may include a plurality of body portions, and by coupling the extension portion to the plurality of body portions, it is possible to couple a plurality of artificial tooth root implants through the extension portions.

Dental component (1) for the individual prosthetic reconstruction of a tooth, intended to be received on a dental implant, comprising: a first element (3) with an angled through-passage (4), a second element (7) intended to be received against or in a dental implant (2),

Means of assembly (9, 13a-13c) between the first (3) and second (7) elements make it possible effectively to limit the removal of material to be performed in the first element (3) in order to create the angled through-passage (4).

An implant fixture is disclosed. The implant fixture contains an elongated shaft section, a head section, wherein the head section comprises at least one concave area for bone growth therein, and a protrusion extending from the head section.

The method is used for making a dental prosthesis or for the adaptation of an existing dental prosthesis for the inclusion in and attachment to existing residual dentition and/or at least one implant. Here, individual teeth and/or implants and/or the remains thereof form the anchor elements for anchoring the dental prosthesis. First, an imprint of the actual condition of the jaw of the patient occurs, from which a master model and a working model are molded. Then, the working model is adjustably fixed in a milling base and aligned with respect to the insertion direction in a milling machine or parallelometer. Next, adhesion surfaces (2) made from wax in the manner of wide-area brackets, an adhesive bridge or the like are molded onto the molded anchor elements (1). Then a molded connecting part (3) with a permanently attached parallelization pin (4) and/or retention anchor element is waxed thereon after successful alignment with the insertion direction by means of the parallelization pins (4). Subsequently either the teeth (7) forming the dental prosthesis, the cast-model framework (8) and further necessary parts are modeled in wax, or the already an existing dental prosthesis are modeled on. Finally the model is provided with injection molding passages (9), and for this purpose each of the elements is worked on individually. Then, the model is embedded and boiled out for removing the wax, and that finally after insertion of the interchangeable matrix (duplicating matrix) into the molded connecting part (3) and surface treatment of the mold inner surfaces and the plaster mold, the mold is removed, followed by the removal of the dental prosthesis.

A method for manufacturing a dental implant apparatus that comprises an implant and an implant support that can be placed next to one another by contact surfaces and that have contours providing security against rotation that are integrally molded on in one piece. The implant and an implant support have mutually matching contours that prevent a rotation of the implant and the implant support when placed next to one another. A tool system for carrying out the described methods and a dental implant apparatus that is manufactured in a corresponding manner are further disclosed. A contact surface of the implant is ground using a first grinding gauge that has a grinding surface having the shape of the contact surface of the implant attachment but not having the shape of the contour providing security against rotation of the implant. The contact surface of the implant support is ground using a second grinding gauge that has a grinding surface having the shape of the contact surface of the implant but not having the shape of the contour providing security against rotation of the implant support.

A dental implant system having a first implant part, provided for introduction into a jawbone, and having a second implant part, provided for attaching a tooth replacement part, the implant parts being mechanically interconnectable via a connection pin which is integrally formed on one of the implant parts and which is insertable into a receiving duct provided in the other implant part, is to have a particularly high stability and long duration of use, even when ceramic materials are used for the implant parts. For this purpose, in a contact region to the receiving duct the connection pin is provided with a spacer formed of a material softer than the material of the connection pin, and the connection pin has a porous surface, in the surface region which is provided with the coating, to form a material fit connection to the coating.

A root assembly includes an implant body and a positioning device connected to the implant body. The implant body has a positioning hole formed through one end thereof and an engaging portion opposite to the positioning hole. The positioning hole has an end edge. The positioning device has a positioning seat where an artificial tooth is attached and a positioning unit extending through and out of the positioning seat. A first recognition portion is formed on the positioning seat. The location of the first recognition portion of the positioning seat corresponding to the end edge of the positioning hole can recognize that the positioning device is exactly positioned on the implant body, thereby preventing the positioning device from loosening.

Disclosed herein is a cleaning system (30) for a dental implant part (2) that has been introduced into the jaw bone of a patient. For this purpose, in an advantageous embodiment of the invention, a securing element, which is adapted on the end side to connect to a corresponding connection element in the dental implant part, particularly preferably which can be screwed into a thread of the dental implant part by the end side, and to which a distribution element for a cleaning fluid as well as an electrical contact element can be attached, which distribution element can be connected to an external media reservoir via a media channel, and via which electrical contact element, a power source that is connectable to an external power source can be electrically connected to the dental implant part.

A dental implant system includes a dental implant, an abutment adapted to be inserted in an axial hole of the dental implant, and a locking screw adapted to be inserted in an axial through-hole of the abutment and to be screwed into the axial hole of the dental implant. The axial through-hole defined in the abutment includes a frustoconical portion configured to come into contact with a correspondingly frustoconical portion of the locking screw, wherein the median circumference of the frustoconical contact surface between the abutment and the tightening screw is configured to be disposed under the crest/connection line.
