US 4,732,564 A · Dental implant alignment and bending apparatus

Abstract

Apparatus includes a mandible alignment device and a jaw pattern jig to prepare a one-piece metal dental implant for insertion into a patient's mouth. The alignment device has a central scissors member with a rear positioned thumb wheel controlling the longitudinal spread of the scissors blades. A front portion of a longitudinal angle adjustment member mounted over the scissors holds an anterior foot portion of a dental implant. A rod integral with the end of each scissors blade supports a housing holding a ramus member portion of a dental implant. After a pattern is determined by the alignment device, it is locked into the jaw pattern jig and the one-piece metal dental implant is bent to shape to substitute for the anterior foot and ramus members removed from the alignment device.

Dependent claims

Dental implant aligning device for duplicating the alignment of the component parts of a patient's mandible comprising:

(a) a scissors member having two crossing blades with front and rear ends, the front end of each blade integral with a rod enclosed within a movable housing and the rear end of the blades bridged by a screw member having a centering thumb wheel mounted on the screw,
(b) a front and back movable longitudinal adjustment plate mounted over the scissors, the plate having a rearwardly directed slot enclosing the thumb wheel and a front member adjacent an anterior foot portion of the aligning device;
and
(c) the movable rod housing having a means at a rear end for advancing or retracting the housing in relation to the rod, the movable housing having a swivel fitting mounted in a front end, the swivel fitting integral with a locking element capable of capturing a ramus member portion of the aligning device.

1 more element

A dental implant aligning device in combination with a jaw pattern jig to establish the alignment of a one piece metal mandible implant comprising:

(a) as part of the jaw pattern jig a base plate having multiple left and right spaced apart bores,
(b) a left and right positioning device, each positioning device having a means, affixed to the base plate by a screw engaged to one of the bores, for supporting a position shaft having a slot for capturing a distal end of a ramus member,
(c) an anterior end of each ramus member being captured by a locking element of the implant aligning device,
(d) the implant aligning device having a scissors member with two crossing blades, a front end of each blade integral with a rod enclosed within a movable housing, the movable housing having a front mounted swivel fitting integral with the locking element,
(e) a longitudinally movable adjustment plate mounted over the scissors and supporting a rod integral with an anterior foot member of the dental implant at a front end,
(f) a vice tightening screw mounted on the jaw pattern jig between the scissors blades of the implant aligning device, the vice tightening screw moving a first block in a slot of the jig to capture the anterior foot between the first block and a second block permanently affixed to the slot in the jig, the position of the implant aligning device together with the ramus members and anterior foot member being thereby precisely aligned.
