Gummy smile showdown: which surgery works best?

NCT ID NCT07334015

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This completed trial tested two surgical procedures to reduce a gummy smile (excessive gum display when smiling). Sixteen women aged 18 to 30 received either a modified lip repositioning surgery or a Z-plasty frenectomy. Researchers measured how much the gum show decreased, pain levels, and how satisfied patients were. The goal was to find which technique offers better results and recovery.
