OBJECTIVE: To develop a modified presurgical nasoalveolar molding (MPNAM) with a premaxillary appliance, connected with two stainless steel wires and evaluate its therapeutic efficacy in newborns with complete bilateral cleft lip and palate (BCLP). METHOD: A total of 41 patients with neonatal complete BCLP having a severely protruded and deviated premaxilla were retrospectively selected from January 2017 to November 2019. All patients received the MPNAM device with a premaxillary appliance which was worn until cheilorrhaphy. Plaster casts from pre- and post-MPNAM treatments were scanned using a three-dimensional laser scanner, and the changes were recorded. Facial photographs of patients were taken during the treatment. RESULT: The average MPNAM treatment duration was 59.8 days. In all cases, the protrusive and deviated premaxilla was rapidly retracted and set into a suitable position after MPNAM treatment. The relative deviation distance and alveolar cleft width were significantly reduced. Both mid-palatal arch width and posterior arch width were increased. In addition, none of the patients developed any complications during the MPNAM treatment. CONCLUSION: Our MPNAM device was able to rapidly centralize the malpositioned premaxilla and reduce the alveolar cleft defect. This device can be applied in presurgical orthodontic treatments for patients with complete BCLP having a severely protruded and deviated premaxilla. AJTR
