METHOD FOR SIMULATING BONE-RECONSTRUCTIVE SURGERIES IN TREATING NEW GROWTHS OF JAW BONE IN CHILDHOOD

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely, to maxillofacial surgery and orthodontics. For simulating bone-reconstructive surgeries in treating new growths of jaw bone in childhood is carried out KT examination of skull with subsequent reconstruction in 3D programs and create a three-dimensional model of skull, identify new growth, calculate basic parametric data of neoplasms and virtually it is removed in the resulting model, then virtually fill a defect or flaw, then prototyping reconstructive models of jaws or endoprosthesis using a 3D printer. For virtual removal of neoplasm is performed a 3D cephalometry, on the received 3D model of skull manually placed cephalometric marks at maximum increase of screen resolution, using simultaneously different projections, perspective, right, left, top, front and by varying the transparency of the image from 0 to 100 %, determined 48 cephalometric parameters against which is carried out a virtual replacement of defect or flaw zone with subsequent virtual correction of jaw bones during the staged orthodontic-surgical treatment.;EFFECT: method allows to simulate and predict the staged surgical-orthodontic and orthopaedic treatment in a child until its growth, as well as reduce a probability of unplanned step operations.;1 cl, 21 dwg, 4 tbl, 1 ex
