摘要:
Implant (la, lb) for dental prostheses, comprising at least one endosseous portion (2) and at least one stump (3), said endosseous portion (2) comprising a crown margin (24) suited to be opposed to a corresponding crown margin (33) of said stump (3). At least one of said crown margins (33, 24) is conical or however has a different taper with respect to the opposed crown margin (24, 33) so that, once said stump (3) has been grafted on said endosseous portion (2), the contact and interference surface (51) between said crown margins (33, 24) is a reduced annular surface.
摘要:
A dental abutment, or a dental implant having an integrated abutment, in which the occlusal part of the abutment to which the dental prosthesis is to be cemented features a shoulder having a reverse margin. At the point where the shoulder meets the outer profile of the gingival part of the abutment, the shoulder is at an acute angle with respect to the longitudinal center axis of the abutment, thereby causing any cement ejected during mounting of the prosthesis to be ejected in a direction away from the gingiva.
摘要:
The present invention relates to multi-piece dental implants comprising an anchor and abutment assembly and in particular, to such a dental implant system and an insert adaptor that facilitates coupling between an implant anchor and an abutment member may be coupled over a single position one-way coupling interface in a one to one manner, where the one-way coupling interface may be integrated with an anchor or coupled to an off the shelf anchor in the form of an insert.

Die vorliegende Erfindung betrifft ein Aufbauelement (10) zur Fixierung von implantatverankerten, herausnehmbaren Zahnprothesen, enthaltend ein unteres Ende (13) zur Befestigung des Aufbauelements (10) mit einem Implantat (21) oder Abutment; ein oberes Ende zur Verbindung des Aufbauelements mit einer Zahnprothese, optional einem Friktionseinsatz; dadurch gekennzeichnet, dass der Grundkörper des Aufbauelements (10) einen Außenring (11) aufweist.
摘要:
A premade ceramic dental implant abutment includes a ceramic abutment (10) having at the top a support region (30) intended for receiving a mating prosthetic build-up construction with a surface feature (40) to inhibit rotation of said construction, and at the bottom, an implant contact region (50) with geometry to connect to the implant. The ceramic abutment (10) has a passageway (70) extending therethrough. The passageway (70) may narrow to form a shoulder (80) that is made entirely of ceramic. A head of a screw seats entirely on the shoulder (80). The ceramic abutment (10) has a supragingival region for protruding beyond the gingiva and a subgingival end for extending into the gingiva. The ceramic abutment (10) may be free of metal. Also, the premade ceramic abutment (10) may be designed to be augmented by cementing additional ceramic material such as a ceramic prosthesis onto the ceramic abutment (10).

Zahnimplantat, umfassend einen bereichsweise in einen Kieferknochen inserierbaren Sockel (10) mit einem apikal gelegenen Körper (12) und einem koronal gelegenen Hals (14), deren äußere Oberflächen jeweils eine Oberflächen-Mikrostruktur vorgegebener Rauheit aufweisen, wobei der Wert der mittleren Rauheit der Körperoberfläche größer ist als der Wert der mittleren Rauheit der Halsoberfläche, wobei der Wert der mittleren Rauheit der Körperoberfläche Ra = 0,75 bis 0,95 Mikrometer und der Wert der mittleren Rauheit der Halsoberfläche Ra = 0,55 bis 0,71 Mikrometer beträgt.
摘要:
A method (Fig. 7) of attaching a dental implant (10, 20, 30, 40, 50) includes the making of a dental implant having the general shape and size to fit a bone cavity for a removed tooth plus a cylindrical extension prong (12, 22, 23, 32, 52) to fit a drilled bore in the bottom of the cavity formed by the removed tooth. The method includes extracting a patient's tooth (72), selecting a drill guide (73) having the general shape of the bone cavity from the removed tooth and having a bore therethrough, then passing a drill bit through the drill guide bore and drilling (75) a bore in a predetermined position in the bottom portion of the bone cavity. The dental implant (10, 20, 30, 40, 50) is selected (76) of a predetermined size and anchored in the bone cavity.
摘要:
Implante dental utilizado como soporte y sujeción de los elementos prostéticos que sustituyen a las piezas dentales originales y especialmente indicado para situaciones con compromiso estético y reducido espacio disponible debido a la presencia de piezas adyacentes o por la geometría del hueso que básicamente comprende un cuerpo central (2) roscado y una plataforma (1) de diámetro comprendido entre 3,1 y 3,5 mm de forma exterior e interior cónica que se prolonga por medio de un orificio roscado (4) para la retención de un pilar (3) de unión a la prótesis.
