摘要：
FIELD: medicine.SUBSTANCE: X-ray examination of the patient suffering discontinuous dental arch. A value C of periodontal supporting tissue atrophy is determined by formula: C=100-(L1 X 100)/L, wherein L is an overall length of root measured in a coronary window of a multi-plane image restoration of a retainer tooth with specifying a section, wherein a root length, or a medial root length for multi-rooted teeth, is maximum to this end, points on an enamel-cement border are connected by means of using a Length measuring instrument a distance of interest to an apex point of the root is measured from the point found in the middle of the produced line L1 is an effective length of the root measuring by the above Length measuring instrument in the same mode from the apex of the root to a point of intersection of a segment of the line connecting apex points of closing cortical plates and the line L describing the overall length of the root. If the value C of periodontal supporting tissue atrophy within the retainer teeth is less than 25%, a working periodontal area is stated sufficient to preserve the teeth expected to be retainers stable, i.e. the masticatory efficiency occurs to be preserved. If the value C of periodontal supporting tissue atrophy is more than 25%, the working periodontium is stated to decrease by 55%. An integral rate of the masticatory efficiency of the expected retainer teeth is determined by using reduction factors of the masticatory efficiency, which are determined by multiplying the periodontal value N within the above intact tooth by the respective rates of the masticatory efficiency of the teeth from Table 2.EFFECT: by more accurate determination of the masticatory efficiency of the retainer periodontium, the method enables preventing complications related to overload of the periodontal supporting tissues accompanying a prosthetic repair procedure.1 dwg, 2 tbl, 1 exСпособ относится к медицине, а именно к стоматологии, и предназначен для использов
