Theravex Oral and Theravex Tissue Care Plus to improve healing after mucogingival surgery

Clinical Study on the Efficacy of Theravex Oral and Theravex Tissue Care Plus in Periodontal Surgery" Modified Free Gingival Graft for the Treatment of RT1-RT2: A Randomized Clinical Trial

Not applicable Interventional Universidad Complutense de Madrid · NCT07430670

We will test if applying Theravex Tissue Care Plus during a modified free gingival graft and rinsing with Theravex Oral afterward helps adults with lower-front gum recession heal faster and get better root coverage than a saline placebo.

What this trial studies

This randomized, double-blind trial at the Complutense University of Madrid enrolls adults with RT1–RT2 gingival recessions on mandibular incisors who require a modified free gingival graft (M-FGG). Participants are randomly assigned to receive either Theravex Tissue Care Plus applied to the graft and recipient site plus 14 days of twice-daily Theravex Oral rinses, or the same surgical protocol with a blinded saline placebo. The primary outcome is reduction in recession depth at 12 months, and secondary outcomes include keratinized tissue width, soft tissue thickness, volumetric 3D changes, tissue color integration by spectrophotometry, vascularization by Laser Speckle Contrast Imaging, and postoperative pain. Follow-up includes clinical exams and digital imaging over a one-year period.

Who should consider this trial

Good fit: Healthy adults (≥18) with at least one RT1–RT2 recession on a mandibular incisor, shallow probing depths (≤3 mm), low plaque levels, and willingness to attend scheduled follow-ups are the ideal candidates.

Not a fit: Smokers of ≥10 cigarettes/day, pregnant patients, those with uncontrolled systemic disease, untreated parafunctional habits, or incompatible dental restorations are unlikely to qualify or benefit.

Why it matters

Potential benefit: If successful, the treatment could produce better root coverage, increased tissue thickness and color match, and less postoperative pain after gum graft surgery.

How similar studies have performed: Preclinical data for the Bone Bioactive Liquid show promising effects on hard and soft tissue regeneration, but clinical evidence for these specific Theravex solutions in mucogingival surgery is limited and the approach is relatively novel.
