Orthodontic premaxillary setback versus premaxillary osteotomy with gingivoperiosteoplasty for Bilateral cleft lip and palate patients: 4-year observation outcomes

摘要

Patients with bilateral cleft lip and palate (BCLP) generally require several stages of treatment, and adequate maxillary development without orthognathic surgery is not easy to achieve. The purpose of this study was to determine short-term outcomes of orthodontic premaxillary setback (OPS) and premaxillary osteotomy (PO) for complete BCLP treatment.
