Aim: The aim of this study is to examine the distribution of intra-osseous dental implants in the mandible and maxilla applied to correct 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 dental implant treatment at our clinic between 2011 and 2016 were retrieved from archival records. Patients with a missing single tooth in the mandible and maxilla who had an implantation in three different diameters (4.1 mm, 4.5 mm, 4.8 mm) were included. The anatomical localizations, height characteristics and rate of losses concerning the implants were analyzed by descriptive statistical analysis.
Results: Of the 180 patients, 79 received dental implants with a diameter of 4.1 mm; 49 received dental implants with a diameter of 4.5 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 in the 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 commonly used 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 the premolar 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 to patients aged 30 to 40 years. Treatment with single-tooth implants was shown to be a successful treatment with a high survival rate when factors such as implant diameter/length and age/sex of the patient are considered.
