Summary

This study tests two ways to attach dentures to dental implants in the lower jaw: a traditional bar and a bar with a special cap. 22 adults who have lost all lower teeth will get implants and be randomly assigned to one attachment type. Researchers will measure how well the denture stays in, bone loss around implants, and patient satisfaction over 6 months to find the better option.
