ClinConnect Summary

This clinical trial is studying how a removable complete denture, along with a single implant placed in the lower jaw, affects hearing ability in patients aged 50 to 65. Researchers will measure hearing changes at different times: before and after using the denture, before and after the implant surgery, and after the denture is attached to the implant. The goal is to see if this treatment helps improve hearing for people with specific hearing thresholds.

To participate in this trial, individuals need to be between 50 and 65 years old, have enough bone in their jaw for the implant, and should not have used removable dentures before. Participants must also be able to commit to follow-up appointments and complete questionnaires about their experience. Those with certain medical conditions, like uncontrolled diabetes or high blood pressure, or who use hearing aids, will not be eligible. If chosen to participate, patients can expect a structured process that involves surgery and regular assessments of their hearing.
