What this Trial Is About
This research compares two surgical methods aimed at improving soft tissue volume in areas where teeth are missing. Both techniques, connective tissue graft and volume collagen matrix xenograft, have been validated before, but limited data exist about their differences. The goal is to assess volumetric changes and gather clinical measurements alongside patient satisfaction over time. Participants will be randomly assigned to one of two groups Group A receives the connective tissue graft, considered the gold standard and control, while Group B receives the experimental collagen matrix xenograft called Geistlich Fibro-Gide4. Soft tissue changes will be monitored using intraoral scans before and after surgery, including follow-ups up to 5 years post-operation. During the study, participants will undergo assessments such as clinical evaluations of tissue health, patient-reported satisfaction and discomfort, and prosthetic outcomes. Researchers will use advanced software to measure volume changes and track various clinical and radiographic parameters over 5 years. The study includes regular follow-ups and safety monitoring throughout this period.
