Comparing a new 3D tunneling technique with a modified coronally advanced tunnel plus connective tissue graft for treating multiple RT2 gingival recession.
Comparative Evaluation of Novel 3D Tunneling Technique Versus Modified Coronally Advanced Tunnel (MCAT) With Connective Tissue Graft in the Management of Multiple RT2 Gingival Recession: A Randomized Controlled Trial
This trial will try a new 3D tunneling surgical technique versus a modified coronally advanced tunnel with connective tissue graft to improve root coverage in adults who have multiple RT2 gingival recessions.

What this trial studies
This interventional comparison tests a novel 3D tunneling (3DT) surgical approach against the modified coronally advanced tunnel (MCAT) combined with connective tissue grafts for managing multiple adjacent Cairo RT2 gingival recessions. Eligible adults with good oral hygiene and healthy systemic status will receive one of the two root-coverage procedures and be followed with standard clinical measurements of recession depth and papilla/interdental root coverage. The protocol excludes smokers, pregnant or lactating patients, those with restored or non-carious cervical lesions, recent periodontal surgery at the site, or systemic compromise. The goal is to document whether 3DT provides better interdental root coverage and longer-term stability than MCAT with grafting.
Who should consider this trial
Good fit: Ideal candidates are adults (≥18) with multiple adjacent buccal and lingual Cairo RT2 recession defects, healthy systemic status, good oral hygiene (full mouth plaque index <20%), and a desire for root coverage.
Not a fit: Patients who are smokers, systemically compromised, pregnant or lactating, have restored teeth or non-carious cervical lesions, recent periodontal surgery at the site, or who are non-compliant are unlikely to benefit from enrollment.
Why it matters
Potential benefit: If successful, the 3D tunneling technique could provide improved coverage of interdental exposed root surfaces and more stable papilla reconstruction leading to longer-lasting root coverage.
How similar studies have performed: Several case reports and small clinical studies have shown promising outcomes with the 3D tunneling technique and established MCAT plus connective tissue grafts are effective for mid-facial root coverage, but long-term comparative data are currently lacking.
