Evaluation of 107 dental implant treatments at the restorative dentistry clinics of the Lagos University Teaching Hospital

Abstract

Objectives: Evaluation, review, and audit of dental implant treatment done in a hospital aids and contribute to improvement of treatment outcomes. This study reviewed dental implant treatment in a teaching hospital to develop a guide for successful future implant treatment. Methods: Records of patients who received dental implant treatment between 2012 to 2020 in the teaching hospital were retrieved. Patient's sociodemographic data, location of teeth replaced, type of surgical and loading protocol, brand of implant, survival rate of implants at 3, 6, 9 months and 12 months after loading of implants were obtained, immediate or delayed loading protocols was used. Three systems were used, the survival of implant and complications recorded during the 12 months review period. Data entry and analysis was performed with SPSS version 22. Results: A total of 75 participants comprised of 25(33.33%) males and 50(66.67%) females. The age range was 21 to 72 years. A total of 107 dental implant were placed Two thirds (72) implants were delayed loading, while 35 were loaded immediately. Delayed implant loading had a higher survival rate (87.5%) compared to immediate implant loading (80%). Mandibular implants had a significantly higher survival rate compared to maxillary implants (100% and 79.2% respectively; p value=0.387. Posterior implants had a higher survival rate than anterior implants, (91.3% and 80.3% respectively; p value=0.387 Conclusion: Loading protocol does not significantly affect implant survival rate. Implants placed in the mandible had a remarkably high survival rate because of quality of bone.
