Comparing Buccal Fat Pad and Palatal Rotation Scarf Grafts for Improving Soft Tissue Around Zygomatic Implants in Patients With Severe Upper Jaw Bone Loss

What this Trial Is About

The trial investigates the use of zygomatic implants to treat patients with severely atrophic upper jaws who cannot receive standard implants due to insufficient bone. The study compares two methods of soft tissue augmentationbuccal fat pad graft and palatal rotation scarf graftto find which better improves tissue volume, stability, and prevents soft tissue complications around these implants. This research aims to enhance long-term outcomes and reduce complications in challenging oral rehabilitation cases. Participants will receive zygomatic implants placed using the Exteriorized ZAGA approach, either alone or combined with axial implants when bone allows. They will be randomly assigned to receive one of two soft tissue grafts after implant placement the buccal fat pad graft, known for its stem cell properties and tissue engineering potential, or the palatal rotation scarf graft, which uses well-vascularized palatal tissue to protect mucosal tissues and provide lasting stability and esthetics. During the six-month follow-up, participants will undergo assessments of soft tissue condition and quality around the implants, focusing on peri-implant soft-tissue recessions. Implant survival rates will also be monitored. The study includes regular clinical evaluations to track healing, tissue volume, and implant success, with the total participation lasting at least six months after treatment.
