Assessment of Soft Tissue Thickness Following Utilization of Buccal Pad of Fat Versus Platelet-rich Fibrin for Covering Zygomatic Implants: A Randomized Clinical Trial

Recruiting now · Not applicable

Conditions studied: Soft Tissue Augmentation at Dental Implants

In brief

Would buccal pad of fat be comparable to platelet rich fibrin for Zygomatic implant coverage as a step for reconstruction of atrophic posterior maxilla, in terms of peri-implant soft tissue thickness and avoiding complicated postoperative sequalae?
