摘要:
The present invention relates to a dental implant comprising a dental implant basic body (10) extending along a longitudinal axis A from an apical end (12) to a coronal end (14) arranged opposite to the apical end, said dental implant basic body comprisingan anchoring part (16) facing the apical end and intended to be anchored in bone of a patient, and a head part (18) facing the coronal end and intended to form the basis on which a suprastructure is mounted. The anchoring part comprises a shaft (20) having a basic form that is substantially cylindrical or that tapers in the direction toward the apical end in a cone-like manner. At least a portion of the shaft forms a bone tissue contact region (22), the outer surface of which forming a bone tissue contact surface (30). Coronally to said bone tissue contact region a soft tissue contact region (24) is arranged, the outer surface of which forming a soft tissue contact surface (32). According to the invention, the dental implant further comprises nanostructures formed on the soft tissue contact surface, said nanostructures extending in at least two dimensions to 200 nm at most.

摘要:
Prosthetic element for bone extremities such as fingers or toes, or teeth, comprising a trabecular part (20, 40, 120) and two end parts or stumps (12, 34, 112; 15, 39, 115).
摘要:
Die Erfindung betrifft einen Implantatformkörper, der im knöchernen und/oder Weichteilbereich platziert werden kann. Hauptanwendungsgebiet ist die zahnärztliche Implantologie. Der Erfindung liegt die Aufgabe zugrunde, einen Implantatformkörper anzugeben, der nach teilweiser oder gänzlicher Einbringung in den Extraktions-/Fraktur- und/oder Wundraum die körpereigenen Strategien zum Fraktur/Wundverschlusses weitestgehend nicht behindert und einen aseptischen fibrinogenen Verschluss ermöglicht. Erfindungsgemäß wird die Aufgabe mit einem Implantatformkörper, dadurch gelöst, dass mindestens ein mit einer Verbindungszone aufweisender Ankerkörper vorhanden ist, wobei der Ankerkörper die Form eines Ellipsoids aufweist.
摘要:
An implant system for securing a prosthesis to a selected bone of a subject including a stem and an abutment. The stem includes a porous region that promotes osseointegration of the selected bone following implantation of the stem. The abutment is secured to the stem and is configured for secure attachment to the prosthesis. The stem and the abutment include ultra-low friction and/or highly polished surfaces at select locations that inhibit bio-adhesion.
摘要:
The invention relates to a dental component, such as an abutment, an abutment replica, an abutment blank, a customized abutment, a scan abutment, a digital transfer coping, an impression pick-up element, a healing cap or a driver, comprising at least one first indexing element and at least one second indexing element having an apical end located apically of the apical end of said first indexing element, wherein the second indexing element is designed to present a play with mating features of a dental fixture. The invention also relates to a dental implant which comprises a dental component having first and second indexing elements and a dental fixture having third and fourth indexing elements, wherein any play between the first and third indexing elements is smaller than a play between the second and fourth indexing elements. The invention also relates to a dental fixture.
摘要:
A monolithic material including a first region having a first variability of strength and a second region joined to the first region, the second region having a second variability of strength, wherein the monolithic material has a variability of strength less than the first variability of strength of the first region and less than the second variability of strength of the second region.
