[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-sensitive and can thus atrophy or be resorbed during the healing and building phase. 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. [0004] The aforementioned and other known substances which serve for regenerating and reconstructing bone, including bone blocks, are in the following referred to as bone replacement materials. [0005] The invention has the object to avoid the aforementioned disadvantages of atrophy, i.e., constrictions between the implant and all other bone deposits and repair locations as well as respective contour changes. SUMMARY OF THE INVENTION [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. [0008] While known implants for the dental jaw area are provided with roughened surfaces, depressions, or penetrations, the present invention suggests pin-shaped, for example, cylindrical, implants which are polished at their exterior surface and are thus so smooth that in the implanted state they can be rotated, when applying a force, about its longitudinal axis even after having been implanted for an extended time period. Also, it is especially advantageous in this context when the implants are provided with an outer thread. These implants are height-adjustable by rotation and, in the case of bone reconstruction to be carried out step-wise, can be adjusted with respect to their relative vertical position by sequential steps of approximately 4 mm after an initial a build-up phase of approximately nine months. The bar connected thereto is then also raised accordingly. [0009] After regeneration, the implants can be removed or support elements for dental replacements or prostheses (crowns, bridges, etc.) or other utilitarian elements can be provided. BRIEF DESCRIPTION OF THE DRAWINGS [0010] The object and advantages of the present invention will appear more clearly from the following specification in conjunction with the accompanying drawings, in which: [0011] FIG. 1 shows a plan view onto a longitudinal section of a bar which is suitable for regeneration of the jaw bone; [0012] FIG. 2 shows the bar section according to FIG. 1 in a side view; [0013] FIG. 3 shows a bar in a plan view which is slightly differently embodied as the one shown in FIG. 1; [0014] FIG. 4 shows the bar section according to FIG. 3 in a side view; [0015] FIG. 5 shows an implant in an end view which can be used in connection with the bar of FIGS. 1-4; [0016] FIG. 6 shows a section along the line VI-VI of FIG. 3 together with an implant according to FIG. 5; [0017] FIG. 7 shows a schematically represented longitudinal section of the regeneration area of a jaw bone to be reconstructed; [0018] FIG. 8 shows a part sectional view of the fastening element for a bar; [0019] FIG. 9 shows a schematically represented longitudinal section of the regeneration area of a jaw bone to be reconstructed with a bar according to FIGS. 3 and 4 bent into a bridge structure; [0020] FIG. 10 illustrates schematically a bar according to FIGS. 3 and 4 in a differently bent bridge structure; and [0021] FIG. 11 illustrates schematically a bar according to FIGS. 3 and 4 in a differently bent bridge structure.
