Comparing Soft Tissue Coverage Techniques Over Zygomatic Implants in Patients with Severe Maxilla Bone Loss Using Buccal Fat Pad and Palatal Pedicle Flap

What this Trial Is About

Researchers are investigating two methods of soft tissue coverage over zygomatic implants in patients with severely atrophied maxilla. The study aims to compare the Buccal Fat Pad flap, a common technique using vascularized soft tissue from the cheek, with the Palatal Pedicle Flap, which uses thick keratinized tissue from the palate. This randomized controlled clinical trial uses a split-mouth design where each patient receives both treatments on opposite sides to reduce variability and improve comparison accuracy. The trial involves patients with bilateral zygomatic implants placed in the upper jaw. On one side, the Buccal Fat Pad is accessed through a mucosal incision, mobilized, and secured over the implant. On the other side, the Palatal Pedicle Flap, containing its vascular supply, is rotated to cover the implant area. Both flaps are fixed with resorbable sutures for tension-free closure. Standard post-operative care, including antibiotics and mouth rinses, is provided. The healing and tissue stability will be assessed over a 6-month period. Participants will undergo evaluations of soft tissue thickness around the implant collar at three points using a periodontal probe. Post-treatment follow-ups will monitor tissue healing and implant environment stability. The study lasts 6 months, during which clinical assessments will document the outcomes of each flap technique. This trial seeks to provide reliable evidence to guide soft tissue management in complex dental implant cases where the Buccal Fat Pad may be insufficient or unavailable.
