Abstract

Introduction
Secondary alveolar cleft repair is commonly accepted for alveolar cleft patients, however, nowadays, controversy remains
regarding the surgical technique, the timing of the surgery, and the donor site. Rehabilitation of the large alveolar clefts with
autogenous graft or distraction osteogenesis is one of the most common treatment choices. The purpose of the report is to
evaluate the surgical techniques for repairing the wide alveolar clefts.
Cases
Four patients with alveolar clefts were included in our case series. The width of the cleft was between 17 to 25 mm. All patients
were treated with distraction osteogenesis. The segmental osteotomy was performed under general anesthesia. Distraction
was started 5 days after surgery. All distractors were bone fixed but supported by a palatal arch for guiding the distraction.
Dental cast models were used before the surgery. Pre and postoperative radiological examinations were performed through
orthopantomogram and computed tomography (CT) scan.
Results
With distraction techniques, closure of the alveolar cleft was achieved. The desired movements with new bone formation were
attained yet eventful in all cases.
Conclusion
The method of treatments described here is a prospect for treating extremely wide alveolar clefts. Further patients are needed
to assess all effects, side effects, risks, and overall benefits of these techniques.
