Summary

This study looks at whether placing a dental implant slightly deeper below the bone helps preserve bone around the implant in people with thin gums. About 30 adults with a single missing tooth will get an implant placed either at bone level or 2 mm below. Researchers will track bone loss, gum health, and patient satisfaction over one year.
