A 1-year parallel-group randomized clinical trial comparing effectiveness of mandibular complete denture versus early loaded single-implant overdenture

Purpose: To assess the effectiveness of converting a conventional mandibular denture (CMD) into a single-implant mandibular overdenture (SIMO). Materials and Methods: Edentulous subjects received a new set of CMDs and were randomly assigned to CMD or SIMO groups. For SIMO patients, a midline, early loaded implant was placed and incorporated into the CMD after 3 weeks. Patient satisfaction and oral health–related quality of life were assessed at baseline and up to 1 year. Regression models were constructed using generalized estimating equations. Results: After 12 months, 32 patients were assessed (CMD: n = 17; SIMO: n = 15). Significant improvement was observed for the SIMO group when compared to baseline measures. Conclusion: SIMO may be considered an effective alternative for patients unsatisfied with their CMDs. Int J Prosthodont 2022. doi: 10.11607/ijp.8157
