ClinConnect Summary

This clinical trial is looking at two different methods for placing zygomatic implants, which are special dental implants used when patients have significant bone loss in the upper jaw (also known as the maxilla). The study aims to see which method, either placing the implants through the sinus or around it, results in fewer complications after surgery. This information could help doctors choose the best approach for patients who need these implants to restore their ability to chew and smile.

To participate in this trial, patients must have a severely damaged upper jaw that can't be fixed with other treatments and enough bone height in the front part of the jaw to support conventional implants. Additionally, candidates should be in good overall health and motivated to undergo the procedure. Participants can expect to receive care from a team of professionals and might contribute to finding the best surgical approach for future patients needing similar treatments. Remember, this trial is currently recruiting participants of all genders, so if you or someone you know fits these criteria, it could be a great opportunity to help improve dental care for others.
