ClinConnect Summary
This clinical trial is investigating a new technique to help reduce excessive gingival display, which is when too much of the gums shows when smiling. The study uses a specially designed PEEK shell placed in the front part of the jaw using a method called tunnel technique. The goal is to see if this approach can effectively improve the appearance of the smile by minimizing the amount of gum that is visible.
To participate in this trial, candidates must be between 20 and 60 years old and have visible excess gum tissue (2.5 mm or more) when smiling. Participants should be healthy and willing to attend follow-up appointments, but those who are pregnant, smoking, or have certain health conditions like diabetes will not be eligible. If selected, participants can expect to undergo the procedure and will be monitored to evaluate how well it works in reducing the gingival display.
