Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to compare mandibular overdentures retained either by mini or standard size implants as a treatment for edentulous adults, in terms of patient-reported satisfaction and oral health-related quality of life. We will also evaluate post surgical discomfort, the success rate of prostheses and implants in the long term, denture quality and costs.
