Abstract
Abstract Supporting grid for the mechanical support of a cover membrane, which membrane covers a bone void filled with a bone replacement material such as hydroxyl apatite granules, particularly a recess in the proper bone tissue of the body, characterized in that the supporting grid is bendable around at least one axis predetermined by the fashioning of the supporting grid.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
159 words
Supporting grid for the mechanical support of a cover membrane covering a bone void filled with a bone replacement material including hydroxyl apatite granules, said void including a recess in the proper bone tissue of the body, the improvement comprising said supporting grid having an outside contour of an annular sector with an outside arc and an inside arc, said supporting grid being bendable in a direction parallel to a surface normal of the supporting grid in an original condition around at least one line, which is located in a plane of the supporting grid, said grid having recesses along the inside arc and along the outside arc with each of the recesses at the inside arc having a narrow channel extending radially inward from the inside arc, then expanding slightly in a circular fashion and then in turn tapering down to a minimum width channel again over a small region and then expanding greatly and subsequently tapering conically.
Claim 2
Dependent Claim
