METHOD FOR BUILDING OF LOWER JAW BONE DEFECT BY WAY OF DISTRACTION OSTEOGENESIS Russian patent published in 2004 - IPC

FIELD: medicine; orthopedics and traumatology; building of lower jaw bone defect. SUBSTANCE: compression- distraction apparatus is fixed on lower jaw; it has plates for fixing apparatus on lower jaw which are made of material enabling their bending by hand to follow bone shape, guide rods, and carriage displaced over the latter by means of drive screw and provided with wires screwed in holes; wires can be released by turning out the screws, shifted within hole, and fixed anew with aid of screws. Bone fragment with wires screwed therein is incised. Using carriage first compression is effected at point of osteotomy, and then incised fragment is displaced over contour of lower jaw part being restored until it is brought in contact with other fragment of lower jaw bone. In the course of displacement fragment is corrected through height. Fixation is made till maturation of regenerate. Proposed method enables displacement of fragment over path following outline of lower jaw part being restored. EFFECT: provision for building lower jaw defects of great length. 1 cl, 19 dwg
