Evaluation of Xenogeneic Collagen Matrix Versus Connective Tissue Graft to Enhance Soft Tissue Profile Around Single Dental Implants in the Aesthetic Zone

What this Trial Is About

Researchers are evaluating two methods to improve soft tissue around single dental implants in the front upper jaw area, focusing on people missing one tooth with enough bone and gum tissue. The study compares a traditional connective tissue graft (CTG) taken from the patient's palate with a less invasive xenogeneic collagen matrix (XCM) to see if XCM can offer similar results while reducing surgery time and donor site discomfort. This trial is randomized and controlled, aiming to enhance implant esthetics and function with fewer complications. Participants undergo detailed digital planning using CBCT scans and intraoral scans to precisely place the dental implant with a surgical guide. After implant placement, they are randomly assigned to receive either the CTG harvested from the palate or the XCM graft applied to the gum. The CTG involves a second surgical site to collect tissue, while the XCM is prepared by moistening and adapting it before securing it to the gum. Both groups receive a screw-retained provisional restoration immediately after surgery to support healing and appearance. During the study, participants will have assessments at baseline, immediately after surgery, and at 3 months to measure soft tissue changes using digital models. Additional evaluations include gum health, bone loss via X-rays, patient pain and swelling reports, aesthetic satisfaction, and surgery time. Follow-up visits extend to 6 months to monitor healing, complications, and tissue condition. The study collects detailed clinical and patient-reported data to compare outcomes and guide future implant treatments.
