Abstract: The invention relates to a bone augmentation piece (1) for filling out a defective area (2) in a bone (3), comprising a main part (5) which is designed to be inserted into said defective area (2) without a gap, wherein the main part (5) comprises a truss-type structure made of webs (6) and cavities (7). The invention also relates to a kit consisting of a bone augmentation piece (1) of this type, comprising an implant inserted thereinto, such as a dental implant. The invention also relates to the use of the claimed bone augmentation piece (1) as a drill jig (18).

Abstract: A method of processing model data representing a body section with bilateral symmetry of a biological organism is proposed that comprises the steps of providing object imaging data representing the body section having one or more defect portions; calculating a longitudinal axis and a lateral axis of the body section based on mathematical analysis of the object imaging data; and determining a mirror plane based on the calculated longitudinal and lateral axes. Said mirror plane allows for reconstructing the one or more defect portions by mirroring one or more corresponding portions having no defects at the mirror plane.
