A Retrospective study of the One Stepped Dentate Cylindrical (OSDC) dental implants of the Neo-Dent system used for single teeth replacement

Purpose: The aim of this study is to evaluate the success of the application of OSDC implants to restore single missing teeth. Methods & Materials: This retrospective investigation involved placement of 54 Neo-Dent system OSDC dental implants in 36 patients. Exclusion criteria was as follows: psychological disorders, bruxism, smoking habit, anticipate lack of patient compliance. The teeth were needed to replace by dental implants as follows: Maxillae, (Incisors 18 implants, Canines 9 implants, Premolars 7 implants, Molars 5 implants). Mandible, (Canine 3 implants, Premolars 9 implants, Molars 3 implants). After the healing period, an envelope flap was made, the abutments installed and open flap impressions provided. Immediately acrylic temporary crowns adjusted and cemented. The dental implants followed after one year of loading. Results: Except two implants in one patient, all other implants were stable and passed our criteria of success at the time of abutment connection and one year after loading, and subsequently all implants were provided with prosthetic restorations. The rate of bone resorption which have been studied by radiography were as follows: the mean of 0.4 mm, miniumum of 0.2 mm and maximum of 0.8 mm. Conclusions: Replacing single teeth with OSDC dental implants of Neo-Dent system can be applied successfully.
