Benefits of technology

A further essential advantage of the invention consists in the fact that there is the possibility of preparing the whole tooth reconstruction, i.e., abutment and tooth crown, in one piece so that the abutment represents the actual reconstruction.
The following possibilities are available in principle:
A. The abutment comes ready for use with a retention shape.
The latter can be prepared ready-made or individually:
a) with a metal core, sheathing of ceramic, or a synthetic or of a composite m...

Problems solved by technology

However, the tooth configurations of each individual assume different manifestations with regard to shape, geometric extent and position within the dental arch, for which reason difficult adjustments are regularly required in the region of the thickening at the gingival aspect of the abutment if one wishes to deviate more or less, with the reconstructed tooth crown, from the predetermined perpendicular indicated by the abutment anchored in the implant head, or to change the root dimensions predetermined by the implant post.
The commercially available range of shapes allows little scope for matching to the desired tooth/not shape and position of the neighboring teeth.
Clearly, such on-the-sp...

Embodiment Construction

FIG. 1 shows the first step in the process of making a tooth reconstruction. The gingiva 1 is prepared surgically between two healthy teeth 5, 6 sufficiently to allow the anchoring of an implant body 3 in the jawbone 2. This implant body 3 has an implant head or socket 4 secured at its gingival end, which serves as an aid to positioning and in this case has the shape of a hexagon. Obviously, other shapes can be used for the same purpose. It will always be necessary, however, to ensure that the degrees of freedom between patrix and matrix are kept to a minimum. The socket 4 serves as an anchoring arrangement for an abutment 7, as shown in the following figures. The implant head 4 has a screw thread 13, for receiving a detachable connection. Obviously, other connection arrangements can also be envisaged. Care must be taken to ensure that the detachable connection will not work loose on its own.

Once healing has occurred following the insertion of the implant body, the abutment 7 may be...

Abstract

In a device for the reconstruction of missing or lost teeth, an implant, which ends in the gingival region, is biologically anchored in a jawbone. The implant itself comprises an implant body anchored in the jawbone and an implant head on the gingival aspect, acting as the anchoring site for an abutment, which in turn forms the reception site for the tooth being reconstructed. The abutment represents the retention shape of the tooth being reconstructed.

Description

FIELD OF THE INVENTIONThe present invention relates to devices and processes for the reconstruction of missing or lost teeth.BACKGROUND OF THE INVENTIONIn the reconstruction of missing or lost teeth according to present-day technique, an implant is secured to the patient's jawbone. This implant, which preferably is made of titanium or a titanium alloy, comprises an anchor pin anchored in the bone and a receiving funnel on the gingival aspect, whose end is located in the gingival region below the gingival contour. An abutment, which preferably consists of titanium or a titanium alloy, is advantageously attached to the implant head via a detachable connection and represents the actual receiving core for a reconstruction of a tooth or a bridging anchor. Towards the gingival opening, this abutment has a thickening, which represents the actual receiving site for the reconstructed tooth crown. The end of the abutment directed towards the oral cavity is firmly joined to the gingival openin...
