    Journal: Angle Orthod; 2011 Jan; 81(1):42-49. PubMed ID: 20936953.
    Abstract:
    OBJECTIVE: To compare the treatment outcomes of rapid maxillary expansion (RME) plus face mask (FM) and LeFort 1 osteotomy + FM during maxillary protraction. MATERIALS AND METHODS: This study was carried on 34 patients all having maxillary retrognathic, anterior cross-bite, Class III skeletal and dental malocclusion characteristics and a concave profile. Eighteen patients with milder maxillary retrognathism were treated with RME + FM. Sixteen other patients with moderate to severe maxillary retrognathism were treated with an incomplete LeFort 1 osteotomy + FM therapy. Cephalometric data were evaluated statistically. RESULTS: Significantly higher values of maxillary advancement and reduced treatment time were achieved with surgically assisted FM therapy. CONCLUSIONS: The surgically assisted FM treatment was more rapid and effective in maxillary protraction compared to the RME + FM treatment.
