Midfacial growth and dental arch relationships in bilateral cleft palate following secondary alveolar bone grafting and orthodontic intervention: Factors predicting a Le Fort I osteotomy at age 18.

Objective: To evaluate midfacial growth and dental arch relationships in patients treated for bilateral cleft lip and palate (BCLP).

Materials And Methods: Data were collected from all patients with BCLP treated at our hospital between 2004 and 2014, with or without premaxillary osteotomy (PO). Dental casts for pre-secondary alveolar bone grafting with PO (SABG + PO) and end-point dental casts were analyzed using the BAURU yardstick scoring system.
