A retrospective analysis of single dental implants in three different diameters

Abstract

Aim: The aim of this study is to examine the distribution of intra-osseous dental implants in the mandible and maxilla applied tocorrect single missing tooth defects in terms of their size and length and retrospectively evaluate the implant loss rate.Material and methods: Demographic data showing the age/sex and dental implant records of 180 patients who underwent dentalimplant treatment at our clinic between 2011 and 2016 were retrieved from archival records. Patients with a missing single toothin the mandible and maxilla who had an implantation in three different diameters (4.1 mm, 4.5 mm, 4.8 mm) were included. Theanatomical localizations, height characteristics and rate of losses concerning the implants were analyzed by descriptive statisticalanalysis.Results: Of the 180 patients, 79 received dental implants with a diameter of 4.1 mm; 49 received dental implants with a diameter of4.5 mm and 52 received dental implants with a diameter of 4.8 mm, making it 221 in total. The mean age of the patients included inthe study was 43.1 years. Of the 180 patients, 105 (58.3%) were male and 75 (41.7%) were female. The length of the most commonlyused implant was 14 mm (34%) with a diameter of 4.1 mm (45.2%). Of the 221 implants examined, 111 were placed on the maxilla(50.22%) and 110 on the mandible (49.78%). Of the implants examined, 18 were implanted in the anterior region (8.14%); 33 in thepremolar region (15%) and 170 in the molar region (77%).Conclusion: This retrospective study found that single-tooth implant treatment covers a wide range of ages, mainly applied topatients aged 30 to 40 years. Treatment with single-tooth implants was shown to be a successful treatment with a high survival ratewhen factors such as implant diameter/length and age/sex of the patient are considered.
