Comparing Collagen Matrix and Free Gingival Graft for Improving Gum Tissue Around Dental Implants Randomized Trial Measuring Soft Tissue Changes and Patient Experience Over Two Years

What this Trial Is About

Researchers are studying the differences between xenogeneic collagen matrices XCM and free gingival grafts FGG for improving the soft tissue around dental implants. The goal is to see how each method affects the width and thickness of keratinized mucosa KM, which helps protect the implant area from tissue recession and damage. This trial will measure both clinical outcomes and patient experiences over short-term 6 months and long-term 1 and 2 years periods. Participants will be randomly assigned to receive either XCM or FGG soft tissue augmentation at the time of healing abutment connection around dental implants. The XCM is a collagen matrix designed to reduce patient discomfort and surgery time, while FGG is a traditional graft taken from the patients own tissue. Follow-up visits will occur at baseline, 2 weeks, and at 1, 3, 6, 12, and 24 months after surgery to assess tissue changes and other health indicators. During the study, patients will undergo clinical evaluations including measuring KM width, thickness, and tissue height using intraoral scans and digital models. Patient-reported outcomes like pain and satisfaction will be recorded shortly after surgery and at 3 years. Additional assessments will track plaque, bleeding, probing depth, bone levels, and implant survival. The total participation may last up to two years with multiple checkups and monitoring of tissue health.
