A dental implant structure includes a fixture fixed to an alveolar bone, an abutment coupled to the fixture and configured to attach an artificial tooth thereto, and a coupling element configured to couple the fixture and the abutment to each other. In the dental implant structure, the fixture includes a lower fixture portion fixed to the alveolar bone and an upper fixture portion coupled to the abutment, a first thread is formed on a part or all of a surface of the lower fixture portion so as to be fixed to the alveolar bone, the lower fixture portion has a shape extending along a rotation axis of the first thread, a second thread is formed on a part or all of a surface of the upper fixture portion, and the upper fixture portion has a shape extending along a rotation axis of the second thread.

Prosthetic dental device comprising a first axial-symmetric intraosseus component, or implant (11) and a second component, or abutment (12) configured to be connected on one side to the first intraosseus component (11) and to support, on another side, a prosthetic dental component.

Provided is a dental implant unit capable of reducing stress. The implant unit includes an fixture, which is assembled to an alveolar bone and includes a long hole therein; an intermediate structure inserted to the long hole of the fixture; and an abutment assembled to the intermediate structure, wherein the lower portion of the long hole of the fixture has a sloped surface, the lower portion of the intermediate structure also has a sloped surface, and at least a portion of the sloped surface of the long hole and at least a portion of the sloped surface of the intermediate structure contact each other.

The present application relates to an abutment system (12) and its use. The abutment system (12) comprises: a soft tissue level abutment part (10) adapted to be attached to a bone level dental implant (40) by means of an abutment screw (56), wherein the abutment system is adapted to selectively support both a cement-retained final restoration (66) and a screw-retained prosthetic component (68; 70). The present application also relates to dental methods.

A temporary alignment system and method for holding a dental coping to an implant abutment using the same threads in the abutment that are used for definitive attachment are disclosed. The disclosed temporary fasteners initially orient and hold a coping against an abutment with a force along the same axis as the semi-definitive screw. The aligned coping can be picked-up in a closed-tray impression process without unscrewing the temporary fastener. Embodiments include threaded posts that release copings from the abutment through axial forces. Some embodiments include a threaded post with separable cap that is picked-up with the coping. Methods for converting an existing prosthesis for screw attachment to implants in a single visit and digital capture of the converted prosthesis are described.

A dental prosthesis, includes a metal framework having at least one cap, which can be joined to an abutment of a dental implant. The metal framework includes a connecting element which can be, or is, joined to the cap in the oral cavity of a patient, in particular by way of welding, soldering or gluing, wherein the cap has a tip and, on the inside, a cavity into which the abutment can be inserted through an opening located opposite the tip. It is the object to refine the dental prosthesis and/or the metal framework so as to allow improved handling and/or facilitated creation of the, in particular intra-oral, preferably welded, joint with low design complexity. This object is attained by providing a pin arranged as an axial extension in the region of the tip of the cap and the connecting element is joined to the pin.

It is disclosed a dental implant (130; 230; 330) for promoting hone growth. The dental implant includes an elongated implant body having a coronal end portion (131; 231; 331) and an apical end portion (132; 232; 332), at least one external thread (140; 240; 340) and a flute arrangement having a depth. The flute arrangement has at least two helical flutes (150; 250; 350) that spiral in the general direction of said at least one external thread (140; 240; 340). The flutes (150; 250; 350) propagate with a greater lead than said at least one thread (140; 240 340). The flute arrangement is capable of scraping off and transferring bone debris in the coronal direction of the implant during insertion. It is also disclosed a method of using the dental implant and an implant system according to the present invention.

A top piece for a corresponding pin-shaped dental implant with a platform, which features a first platform surface and a second platform surface, a retention pin placed onto the first platform surface, for mounting of a mesostructure, a connecting pin for connecting the platform with a blind bore of a pin-shaped dental implant corresponding to the connecting pin, while in a first version, an edge of the platform is bulged in a direction oriented away from the connection pin, and in a second version, a diameter of the platform is large enough, at least in a part of a total angular area that, where the top piece is connected to the corresponding pin-shaped dental implant, in a view from above onto the second platform surface, the platform protrudes over the corresponding pin-shaped dental implant.

A dental treatment method is provided. In this method, a tooth of a patient is extracted and prepared to provide a root part. A root canal in the extracted tooth is prepared and treated. A post of an abutment is fitted into the root canal to attach the root part to the abutment. The abutment having the root part is attached to a dental implant. With the root part attached to the abutment, periodontal connective tissue maintains the jaw bone associated with the extracted tooth, without significant hard tissue loss.

A dental prosthesis with a threaded crown on a post and core includes a dental implant, a post and core having a portion adapted to be inserted into the implant and another portion protruding from the implant, a screw and a crown, the implant being adapted to be fixed to a bone and the post and core being adapted to be fixed to the implant with a thread, the crown being fixed to the post and core with the screw, wherein the post and core provides a connection element between the implant and the crown, a separation area being provided between the area where the post and core is housed in the crown and the area where the post and core is housed in the implant, and wherein the portion of the post and core protruding from the implant does not feature a diameter increase.
