Study Summary
This split-mouth randomized controlled clinical trial will test whether a ready-to-use collagen membrane (Star Matrix) can widen the protective band of gum tissue (keratinized gingiva) as effectively as the standard free gingival graft harvested from the palate. Central question Can Star Matrix provide the same or better gain in keratinized tissue width-with less patient discomfort and chair-time-than an autogenous graft? Primary objectives Compare the 6-month increase in keratinized tissue width between Star Matrix and autogenous graft sites. Assess patient-reported pain and morbidity associated with each treatment. Secondary objectives Measure operative time, early healing scores, esthetic outcomes, and (optional) histologic quality of the regenerated tissue. Methods Twelve adults with ≤ 2 mm keratinized tissue on contralateral lower-jaw teeth will be enrolled. Each participant receives Star Matrix on one side and a conventional free gingival graft on the other. Follow-up visits at 2, 4, 8, 12 and 24 weeks include clinical measurements, standardized photographs, and a 7-day postoperative pain diary. An optional 2 mm punch biopsy at 6 months is analyzed microscopically.
