METHOD FOR EVALUATING SEVERITY DEGREE OF HUMAN MAXILLODENTAL SYSTEM INJURIES CAUSED BY GUNSHOT WOUND, FOR PRODUCING RECONSTRUCTION PROSTHESIS

摘要

FIELD: medicine. ^ SUBSTANCE: method involves conventionally dividing the maxilla and mandible into three segments of equal value (frontal one and two lateral ones for each jaw) with relation to anatomic fixation points of the reconstruction prosthesis. The total number of fixation units is determined when having in mind that each tooth and each tubercle correspond to one fixation unit, alveolar process and valve zone receive 3 fixation units each and maxillary hard palate also receives 3 fixation units. The number of remaining fixation units are determined in victim having defects in maxilla and/or mandible as a result of gunshot wound, enclosed into the fixing and holding prosthesis parts, and the number of remaining fixation units available in the restoring and forming prosthesis parts. Relation binding the pointed out units are recorded. Severity degree is determined from the following conditions on the number of remaining and failing fixation units: 26.9:0.1 to 17:10 in maxilla cases and 23.9:0.1 to 16:8 in mandible cases show light severity degree of an injury; the number of remaining and failing fixation units being equal to 16.9:10.1 to 13.5:13.5 in maxilla cases and 15.9:8.1 to 11:12 in mandible cases, moderate severity degree of an injury is stated; the number of remaining and failing fixation units being equal to 13.4:13.6 to 0.1:26.9 in maxilla cases and 11.9:12.1 to 0.1:23.9 in mandible cases, heavy severity degree of an injury is stated. ^ EFFECT: high accuracy of evaluation; improved prosthesis quality. ^ 21 dwg
