Tunnel Surgery Combined With a Micro Connective Tissue Graft for the Treatment of Multiple Adjacent Gingival Recession Defects: a Multi-center Randomized Controlled Clinical Trial.

What this Trial Is About

This research aims to evaluate treatment outcomes for multiple adjacent gingival recession defects (MAGRD) using a modified coronally advanced tunnel technique (MCAT) with two types of connective tissue grafts: conventional connective tissue grafts (CTG) and micro connective tissue grafts (micro-CTG). Gingival recession involves exposure of the tooth root due to gum margin displacement. The study compares the effectiveness and predictability of micro-CTGs against conventional CTGs over a 1-year period, focusing on root coverage and patient satisfaction, while also assessing morbidity shortly after surgery. Participants will undergo mucogingival surgery where either a conventional CTG harvested from the palate or multiple micro-CTGs prepared from a harvested graft will be placed on the recipient site and sutured to cover multiple adjacent recession defects. The surgical method used is a modified coronally advanced tunnel. The study includes a control group receiving conventional CTG and a test group receiving micro-CTGs. The follow-up period for outcomes extends up to 1 year, with morbidity evaluated up to 2 weeks post-surgery. During the study, participants will be monitored for root coverage success using measures such as mean mid-facial recession coverage, complete root coverage, changes in keratinized tissue width, and gingival thickness. Patient morbidity is assessed within the first two weeks after surgery, and patient satisfaction is evaluated over the 1-year follow-up. The study involves randomized assignment to groups and triple masking to reduce bias, with participation lasting at least one year.
