ClinConnect Summary

This clinical trial is looking at two different methods for helping patients who have lost bone in the front part of their upper jaw (the maxilla) and need extra bone to support dental implants. One method involves taking a piece of bone from the back of the jaw (the retromolar area) and placing it directly onto the area that needs more bone, which is called an autogenous onlay bone block. The other method uses a thinner layer of bone, known as a cortical shell, also taken from the same area. The goal is to see which method works better for improving the bone structure in these patients.

To be eligible for the trial, participants need to be between 20 and 60 years old and have at least one missing tooth in the front part of their upper jaw. They should have some remaining bone but not enough width (less than 4 mm) to support implants. Additionally, patients should not have any serious health issues that could affect healing, such as uncontrolled diabetes or certain infections. Participants will be monitored throughout the process, and the study is currently looking for volunteers. If you or someone you know meets these criteria and is interested in improving dental health, this trial might be a good opportunity.
