Enhancing Soft Tissues Around Inserted Implants by Two Different Methods

This randomized controlled clinical trial investigates the efficacy of xenogeneic collagen matrix (XCM) versus autogenous subepithelial connective tissue graft (SCTG) in enhancing the peri-implant soft tissue profile around single dental implants in the aesthetic zone of the anterior maxilla. Thirty adult patients with a single missing tooth, adequate bone volume, and sufficient keratinized tissue will be recruited at Damascus University. Each patient will undergo a fully digital workflow for implant planning-including CBCT imaging, intraoral scanning, and CAD/CAM fabrication of a surgical guide and provisional restoration-to ensure precision in implant placement. Immediately following implant insertion, patients will be randomly allocated (1:1) to either receive a CTG harvested from the palatal mucosa using a single incision technique or an XCM (Mucoderm®, Botiss Biomaterials) that is adapted and secured to the buccal mucosa. The primary outcome is the increase in buccal soft tissue profile, measured via superimposed digital surface models at baseline, immediately postoperatively, and at 3 months. Secondary outcomes include patient-reported measures (pain, edema, aesthetic satisfaction), clinical parameters (keratinized tissue width, soft tissue height), peri-implant health assessments, and radiographic assessment. By comparing these two methods, the study aims to determine whether the less invasive XCM can offer outcomes comparable to the CTG standard while reducing donor s…
