Comparing Two Surgical Techniques Using Connective Tissue Grafts for Treating Multiple Gum Recessions MCAT Versus VISTA with 3D Tissue Thickness Analysis

What this Trial Is About

Researchers are comparing two surgical methods for treating multiple adjacent gingival recessions, types RT1 and RT2 the Modified Coronally Advanced Tunnel MCAT and the Vestibular Incision Subperiosteal Tunnel Access VISTA. Both methods use connective tissue grafts CTG to cover exposed tooth roots. This randomized clinical trial aims to assess changes in soft tissue thickness using three-dimensional digital volumetric analysis at six and 12 months. Secondary outcomes include root coverage, esthetic results, gum health, sensitivity, patient satisfaction, and wound healing quality. Participants will be randomly assigned to either the VISTA or MCAT group. The VISTA technique involves remote vestibular incisions and creating a subperiosteal tunnel for graft placement, stabilized with sutures anchored coronally. The MCAT technique uses sulcular incisions without releasing incisions, raising a full-thickness tunnel beyond the mucogingival junction where the connective tissue graft is inserted and secured with horizontal mattress sutures. Both procedures are performed under local anesthesia by periodontal specialists in training. Follow-up evaluations will occur up to 12 months post-surgery. During the study, participants will attend multiple visits for assessments including measurements of soft tissue thickness, root coverage, probing depth, gingival thickness, and oral health impact. Digital tools will be used to analyze tissue changes, and evaluations of hypersensitivity, esthetics, wound healing, and patient concerns will be recorded at various time points from baseline to 12 months. The total participation duration spans from surgery through a year of follow-up to monitor healing and treatment outcomes.
