Abstract:
1. A dry flowable filler structure ( 1 ) for formation of a support structure in an internal bone space ( 4 a ), comprising a plurality of biocompatible support bodies ( 2 ) of identical shape which are not mutually connected and which are resistant to fracture against physiological loads occurring in the internal bone space ( 4 a ), the plurality of support bodies ( 2 ) being configured to allow independent and random arrangement in the internal bone space and having a size between 2 mm and 10 mm, and wherein the support bodies ( 2 ) have an axis (A) and two plane-shaped abutment locations ( 2 g ) oppositely disposed in the direction of the axis (A), wherein the support bodies ( 2 ) are configured to have a polyhedral outer contour with edges ( 2 d ) not being rounded and extending parallel to the axis (A) and to have a 3-edged to 10-edged outer shape with edges ( 2 d ) not being rounded, wherein at least one of the abutment locations has a recess ( 2 c ), and wherein the recess in at least one of the support bodies is configured to lockingly engage with at least a portion of an edge of the outer shape of another support body of the plurality of biocompatible support bodies ( 2 ), wherein the multi-edged outer shape is formed from a plurality of planar surfaces, and wherein the two abutment locations ( 2 g ) extend perpendicular to the axis (A), and further characterized in that the recess ( 2 c ) or an interior cavity ( 3 ) is filled with at least one of an osteo-inductive and an osteo-conductive substance.
