Peculiarities of Implantation in the Posterior Mandible

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.
