The aim of this study is to evaluate using Sticky Bone grafting combined with concentrated growth factor membrane for repair of unilateral alveolar cleft.

This study will be carried out on ten patients with unilateral alveolar clefts, The patients will be recieved, clinically& radiographically examined and managed at Oral & Maxillofacial Surgery Department, Faculty of Dentistry, Tanta University. Preoperative evaluation: Clinical evaluation will include presence of oronasal fistulas, nasal regurgitation and Presence of erupting teeth in cleft. .Preoperative cone beam computed tomography (CBCT) scans will be analyzed to measure alveolar cleft dimensions and the total cleft defect volume will be calculated. Surgical technique: Under general anesthesia, mucoperiosteal flaps will be raised along the cleft margins, exposing the defect. The nasal lining will be sutured with 4/0 Vicryl, followed by the application of a concentrated growth factor (CGF) membrane to cover the nasal mucosa. The sticky bone graft will be packed tightly into the cleft, ensuring complete defect filling. A CGF membrane will be then placed over the graft to enhance stability and healing. The flaps will be sutured using tension-free interrupted 3/0 Vicryl sutures to ensure full coverage of the graft. Postoperative evaluation: The patients will be evaluated over a nine-months follow-up period clinically at intervals of 1st & 2nd weeks, then 1st ,3rd and 9th months for healing parameters such as infection, wound dehiscence, recurrence of oronasal fistulas, nasal regurgitation and graft exposure & radiographically by using CBCT for assessing graft volume, bone mineral density immediate, 3rd & 9th months postoperatively.
