Grafting of the Peri-implant Bony Defects Around Immediate Implants Using Xenogenic Versus Alloplastic Sticky Grafts: Randomized Controlled Clinical Trial

The buccal aspect of the dental implant has great importance, especially in the aesthetic zone, because the buccal bone is very thin especially in the anterior maxilla and its resorption can result in recession of the soft tissue. A gap occurs in immediately placed implant due to discrepancy between the dimensions of the extraction socket and the implant. Augmentation of the buccal gap decreases the amount of buccal bone resorption and soft tissue recession . Filling the peri-implant defects has been widely discussed to prevent further bone loss. The use of biologic materials such as platelet rich fibrin can enhance the quality of alloplastic bone grafts to give comparable effect when compared to xenogenic grafts.
