Device for regenerating, repairing, and modeling human and animal bone, especially in the jaw area for dental applications

Abstract

A device for reshaping human or animal bone with bone replacement material includes at least two spaced apart implants and a bar connected to the at least two spaced apart implants and bridging at least one reshaping location. The bar has notches at the longitudinal sides and transverse grooves at the underside. The bar has slotted holes extending in the longitudinal direction of the bar for receiving the implants, respectively, fasteners of the implants.

Description

[0001] This is a divisional application of Ser. No. 09 / 394,135 filed Sep. 10, 1999 and now allowed. Ser. No. 09 / 394,135 is a CIP application of Ser. No. 09 / 113,031 filed Jul. 9, 1998.BACKGROUND OF THE INVENTION [0002] The present inventions relates to a device for reshaping (regenerating, reconstructing, repairing, and modeling) human and animal bones with any type of bone material, for example, synthetic bone material and bone modeling proteins (BMP), especially in the jaw area for dental applications. Accordingly, the device can be used in all areas of a human or animal skeleton, for repairing and modeling bone portions, for example, also complicated fractions with defective bone areas, whereby the device is not limited to a certain bone shape. [0003] The invention is based on the knowledge that the different materials employed for the regeneration of bone material, for example, a patient's own ground bone material and / or, for example Bio-Oss (trademark), is comparatively pressure...

AI Technical Summary

Benefits of technology

[0006] The present invention suggests a device which is characterized by a bending-resistance bar or strip for bridging reshaping locations, i.e., regenerating, repair, and modeling locations, at the bone and which can be supported by two spaced apart implants. This bar or strip receives pressure forces and thus reduces substantially a pressure loading of the bone replacement materials. Furthermore, the bar distributes locally occurring forces onto larger areas in order to thus reduce specific pressure forces. At the same time, the bar also protects and stabilizes the correlated implants. Also, the bar has the advantage to secure and optionally fasten the membranes which are employed during such regeneration processes, for example, for retaining connective tissue. The membranes can be fastened by guiding the membrane across the bar so that the membrane is supported on the bar.

[0007] Expediently, the bar has two or more penetrations distributed over its length, for example, in the form of slotted holes, through which fasteners, for example, pins or screws, are guided which are secured or screwed into the implant. The slotted holes have the advantage that the bar can be secured at implants having non-uniform spacing between them.

Problems solved by technology

Accordingly, in the known regeneration methods, for example, of the human jaw, atrophies and constrictions as well as bone loss cannot be avoided.

The desired effect of a regeneration or reconstruction as complete as possible, especially in the vertical dimension, can thus practically not be achieved.
