Ten-Year Split-Mouth Follow-Up of Tunnel Technique Using Connective Tissue Graft Versus Acellular Dermal Matrix for Multiple Gingival Recession Coverage: A Case Report

Introduction

Long-term split-mouth comparisons between autogenous connective tissue grafts and acellular dermal matrices using the tunnel technique remain limited in the literature. Gingival recession may lead to root exposure, hypersensitivity, and esthetic concerns. Connective tissue grafts are widely considered the gold standard for root coverage; however, palatal harvesting is associated with postoperative morbidity when multiple sites are treated. Acellular dermal matrix has been proposed as a donor-site-free alternative.
