A Novel Approach for the Reconstruction of Premaxilla by Archwise Distraction in Bilateral Cleft Lip and Palate

Interdental distraction osteogenesis has been introduced as a successful treatment protocol for repairing large clefts. In this article, a new method for reconstruction of the premaxilla in 2 bilateral cleft lip and palate patients is introduced. The aim was to distract the lateral segments through the curve of the dental arch, achieve complete closure of the gaps, and use the premaxilla as a bone graft. Patient 1 (20-year-old female) had double jaw surgery before but presented residual alveolar cleft and small premaxilla. Patient 2 (21-year-old male) had anterior and posterior crossbite and caries of teeth on premaxilla. Following the preliminary fixed orthodontic treatment in both patients, archwise distraction protocol was performed. The distraction duration and the achieved amount of new bone per side were 4 weeks/22 mm and 5 weeks/25 mm in Patients 1 and 2, respectively. At the end of a 2-month retention period, docking side surgery was performed and premaxilla was used as the bone graft. The protocol was very effective for not only closure of the large cleft defects but also the reconstruction of the premaxilla. Anteroposterior relationship and the patients' profiles were considerably and positively affected.
