Predmet. Podvizhnost' i ustoychivost' vnutrikostnyh zubnyh implantatov. Cel'. Opredelenie podvizhnosti i ocenka ustoychivosti vnutrikostnyh implantatov metodom periotesta. Metodologiya. Obsledovano 164 pacienta v vozraste 54,6±4,17 goda. Na verhnyuyu chelyust' ustanovleno 403 implantata, na nizhnyuyu — 238. Po odnoetapnoy metodike ustanovleno 230, po dvuhetapnoy — 411. Issledovaniya provodili srazu posle implantacii, cherez 6 i 12 mes. Ispol'zovan apparat Periotest-M. Pri interpretacii rezul'tatov uchityvali dannye M.M. Uhanova. Statisticheskaya obrabotka vypolnena s ispol'zovaniem programmy Statistica 6.0. Rezul'taty. Pri odnoetapnoy implantacii (230 implantatov, 66 pacientov) srednee znachenie stabil'nosti na moment fiksacii sostavilo -3,48±1,03, v gruppe s dvuhetapnym vidom (411 implantatov, 98 pacientov) — -3,24±1,10. U pacientov s odnoetapnoy implantaciey v verhney chelyusti stabil'nost' po sravneniyu s nachal'noy cherez 6 mes. uluchshilas' na 39,9 (r<0,05), cherez 12 mes. — na 46,3 % (r<0,05). V etoy zhe gruppe v nizhney chelyusti razlichiya mezhdu znacheniyami stabil'nosti v moment implantacii i spustya 6 i 12 mes. sostavili 47,6 (r<0,05) i 53,5 % (r<0,05). U pacientov pri dvuhetapnoy metodike v verhney chelyusti stabil'nost' cherez 6 i 12 mes. po sravneniyu s velichinoy na moment implantacii uvelichilas' na 36,7 (r<0,05) i 44,8 % (r<0,05) sootvetstvenno, v nizhney chelyusti — na 42,9 (r<0,05) i 50,0 % (r<0,05). Razlichiya mezhdu znacheniyami stabil'nosti implantatov v verhney i nizhney chelyustyah ne byli statisticheski znachimymi. Vyvody. Stabil'nost' vnutrikostnyh implantatov sistemy MIS spustya 6 i 12 mes. posle implantacii vozrastaet pri odno- i dvuhetapnoy metodike v verhney i nizhney chelyustyah. Pokazateli stabil'nosti implantatov ukazyvayut na pozitivnyy uroven' osteointegracii.
