Abstract: FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to maxillofacial surgery, and is intended for use in the elimination of congenital and acquired bone defects of complex geometric shape. Examination of the patient, collection of clinical data and results of additional examination methods, CBCT are carried out. In a computer program, the topography, the total volume of a complex defect in the jaw bone in the axial, frontal and sagittal planes, is determined using a 3D X-ray image of the bones of the skull. A blank of a profile template for the external relief of the restoration surface is drawn and the required amount of bone graft material is determined in order to eliminate the defect. The total volume of a complex defect is segmented into geometrically simple segments: internal - hollow and external; the volume of the segments within the design boundaries of the restoration is calculated in turn to determine the total amount of the granular fraction of the granular bone graft material. Sequentially, the volume of each segment is multiplied by the coefficient of natural compaction of the granular bone graft material, after which the volume of the external segment X cm3is multiplied by a factor of 1.25 for the external single-wall segments and the desired volume is obtained for augmentation of the granular bone graft material into the external segment. Then the volume of the internal segment Y cm3is multiplied by a factor of 1.15 for internal multi-wall and the required volume of granular bone graft material is obtained for its elimination into the internal - hollow segment, the calculated volumes for the hollow and external segments are added and the total amount of granular bone graft fraction for placement in the recipient is determined.EFFECT: method, due to the fact that a predictive calculation of the change in parameters of the physical and biological properties of granular bone graft material in the postoperative period is performed, makes it possible to eliminate treatment complications, reduce material costs and optimize the patient's rehabilitation period.1 cl, 6 dwg, 1 tbl, 1 ex
