Abstract

The intra-oral implant consists of two parts. The first part is in the form of a hollow cylinder with an internal screw thread in the upper part. This screw thread runs into a conical bore (7) in the lower part. The lower part has external ridges (4) and a rounded end (5). The wall of the cylinder has two diametrically opposite holes from which slots (2) extend to the rounded end (5). The screw thread receives the second part which is in the form of a screw with a conical end which is driven into the conical bore of the cylinder. The longitudinal slots enable the cylinder to be expanded radially as the screw is driven in. USE - Intra-oral implant.

Description

Das neuentwickelte Zylinderimplantat hat ein integriertes Fixierungssystem. Es hat ein durchgehendes Innengewinde, das in einem gewindelosen Spitzkegel ausläuft. Der Gewindeeingang hat eine konische Schulter, winkelgleich mit dem Spitzkegel.The newly developed cylinder implant has an integrated fixation system. It has a continuous internal thread that is in a threadless cone expires. The thread inlet has a conical shoulder, at the same angle as the Pointed cone.

Eingedreht ist eine Zylinderkopfschraube mit Gewindesackloch, welches verschie dene Aufbauten aufnehmen kann.A cylinder head screw with a threaded blind hole is screwed in, which differs whose structures can accommodate.

Der Zylinderkopf ist unten konisch verjüngt, die Schraube hat am unteren Ende eine konische Spitze, winkelgleich mit der Schulter. Das Zylinderimplantat ist in der oberen und unteren Hälfte ein- bzw. zweifach längsgeschnitzt, die Schlitze sind um 90° bzw. 45° radial versetzt. Sie enden in Querbohrungen.The cylinder head is tapered at the bottom, the screw has at the lower end a conical tip, at the same angle as the shoulder. The cylinder implant is the slots are carved lengthways in the upper and lower halves are radially offset by 90 ° or 45 °. They end in cross holes.

Der Zylinder ist unten gerundet mit spitzwinklig cirkulären Rillen, die Zylin deraußenfläche ist im unteren Drittel längsgerieft, im oberen Bereich gerän delt.The cylinder is rounded at the bottom with acute-angled circular grooves, the Zylin the outer surface is grooved lengthways in the lower third, wrinkled in the upper area delt.

Das Zylinderimplantat wird mit einem Halter in eine exakt passende Bohrung aus reichender Tiefe manuell eingedrückt. Zylinderrand-bündig mit Knochenoberkante. Dann wird die Zylinderkopfinnenschraube mit einer Schraubvorrichtung einge dreht.The cylinder implant is inserted into a precisely fitting hole using a holder manual depth. Flush with the top of the cylinder. Then the cylinder head inner screw is inserted with a screwing device turns.

Je nach der Länge der Innenschraube (Abstand: konische Schulter zu Spitzkegel) wird der ImplantatzylinderDepending on the length of the inner screw (distance: conical shoulder to pointed cone) becomes the implant cylinder

Die mit Gefühl mäßig an die Knochenwandung durch Spreizung angepreßte Zylin deraußenfläche fixiert das Implantat auch gegen Rotation. Dem Einschrauben eines entsprechenden intraoralen Aufbaues und der weiteren Verarbeitung steht der neue Pfeiler zur Verfügung. (Einzeitiges Implantat)The cylin, which is moderately pressed against the bone wall by spreading the outer surface also fixes the implant against rotation. Screwing in a corresponding intraoral structure and further processing the new pillar is available. (Single-stage implant)

Die Zylinderimplantate bisheriger Technik benötigen eine mehrwöchige Einhei lungsphase mit Osseointegration, bis zur Weiterverwendung als Pfeiler. (Zwei zeitiges Implantat)The cylinder implants of previous technology require a unit of several weeks Development phase with osseointegration until it is used as a pillar. (Two early implant)

Claims

Cylinder implant with integrated fixation system as a carrier for various intraoral structures, characterized in that

1. the hollow cylinder has a continuous internal thread that ends in a thread-free hollow cone ( 7 ).
2. the thread inlet has a conical shoulder ( 6 ), the angle of which is identical to the hollow cone at the end.
3. the hollow cylinder in the
Version a in the lower half ( 2 )
Version b in the upper half ( 1 ) is slit once or twice.
Version c is slit lengthways one or two times from above as well as from the bottom up to half or above, but with an offset of the slits around the longitudinal axis of 90 ° or 45 °.
4th
- a) Threaded screw (long) with pointed cone ( 10 ) is screwed in, which expands the implantation cylinder below.
- b) Threaded screw is screwed in with a conical shoulder ( 9 ) matching the shoulder in the implant cylinder, for expansion in the upper part (short).
- c) Threaded screw with pointed cone and conical shoulder, designed so that the implant cylinder is spread at the same time and at the same angle at the top and bottom (medium length).
5. Threaded screw with cylinder head with the same outside diameter as in the plant cylinder on the head side with a longitudinal threaded blind hole ( 8 ) for screwing in superstructures.
6. The implant cylinder is knurled lengthways in the lower third, cross knurled in the upper 2/3.
7. the implant cylinder is rounded at the lower end ( 5 ).
8. has at the lower end one to two transverse grooves ( 4 ) acute-angled cross-section.
