Abstract
Cilj istraživanja bio je provjeriti kliničko-anatomske osobitosti bezubih segmenata stražnjeg dijela donje čeljusti (edentulous mandibular dental segments, eMDS), kao i procijeniti mogućnost implantacije zuba za svaki kliničko-anatomski tip eMDS. U istraživanje je uključeno 198 ispitanika, od toga 88 muškaraca i 110 žena. Procjena eMDS obavljena je s pomoću ortopantomografije, računalne tomografije i kliničke evaluacije uz uporabu posebnog mjernog šestara za greben, namijenjenog mjerenju širine alveolarnih nastavaka. Postavljena su ukupno 353 jednofazna zubna implantata OSTEOFIX, oblika vijka (screw-shaped single-stage Osteofix Dental Implant System). Implantacija je bila uspješna u 346 (98,02 %) slučajeva. Na temelju rezultata mjerenja eMDS, kao i na temelju literaturnih podataka, predlažemo da se dentalni segmenti stražnjeg dijela donje čeljusti podijele u sljedeća tri kliničko-anatomska tipa: I. tip - bez atrofije eMDS, a ako je i ima, ispravna je implantacija moguća; II. tip - moguća je ispravna implantacija, ali uz istodobno pojačavanje alveolarnog grebena; III. tip - moguća je samo odgođena implantacija nakon pojačavanja alveolarnog grebena.The aim of the study was to investigate the clinical-anatomical peculiarities of edentulous mandibular dental segments (eMDS), situated in the posterior mandible, as well as to estimate the possibility of dental implantation for every clinical-anatomical eMDS type. One hundred and ninety-eight patients were examined, 88 male and 110 female. Orthopantomography, computer tomography, clinical examination using special ridge - mapping calipers for measurement of alveolar process width were employed to estimate eMDS. Three hundred anf fifty-three screw-shaped single-stage OSTEOFIX Dental Implant System implants were inserted. In 346 (98.02%) cases implantation was successful. Concerning the results of the eMDS measurements, the literature data suggested the division of posterior mandible dental segments into the following three clinical - anatomical types: type I - atrophy of eMDS is absent or if present, proper implantation is available; type II - simultaneous
implantation is available only with augmentation of the alveolar ridge; type III - only delayed implantation is available after augmentation of the alveolar ridge
