Summary

This study compares a new surgical approach (gingivalstat) to the standard crown-lengthening surgery for people with a gummy smile due to altered passive eruption. The goal is to see which method keeps the gum line more stable over 6 months. About 22 healthy adults will participate, and results will be measured using dental probes and 3D scans.
