Gum surgery showdown: which technique works best?
NCT ID NCT03619096
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aimed to compare two surgical techniques for covering exposed tooth roots caused by gum recession, using a porcine (pig) collagen matrix as a graft material. The trial planned to enroll 20 non-smoking adults with multiple gum recessions. However, the study was withdrawn before any participants were enrolled, so no results are available.
