Comparing two gum tunnel graft techniques (MCAT vs VISTA) to increase gum thickness

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, parallel-group trial will assign 44 adult volunteers with multiple adjacent gingival recessions (RT1 or RT2) to receive either the Modified Coronally Advanced Tunnel (MCAT) or the Vestibular Incision Subperiosteal Tunnel Access (VISTA), both using connective tissue grafts. Periodontal specialists in training at the Universidad Complutense de Madrid will perform the procedures, while the clinical evaluator and statistician remain blinded. The primary outcome is change in soft tissue thickness measured by three-dimensional digital volumetric analysis at 6 and 12 months, with secondary outcomes including root coverage, esthetic results, gingival health, hypersensitivity, patient satisfaction, and wound healing. Follow-up visits will occur at set intervals up to 12 months after surgery to capture clinical and patient-reported outcomes.

* Presence ≥2 mm depth on at least one recession
* Smokers ≤ 10 cigarettes.
* Full-mouth plaque and bleeding scores ≤20%.
* Patients being able to maintain good oral hygiene.

Exclusion Criteria:

* Compromised general health.
