Özet
OBJECTIVE: The aim of this study was to evaluate a modified presurgical nasoalveolar molding (PNAM) treatment for patients with bilateral cleft lip and palate (BCLP) with severely malpositioned premaxillae. SETTING: This study was conducted at the Faculty of Dentistry, Department of Orthodontics, Ege University, Bornova, Izmir, Turkey. METHOD: Retention arms were manufactured using a mold that we developed, and prefabricated retraction apparatuses were applied to the plaster model obtained from the patient. During the acrylic curing process, the flanges of the appliances were elongated into the sulcus without including the premaxilla. The premaxilla was aligned with the midline with an elastic band system, and the lip hanger was constructed with 0.023-in stainless steel wire. Elastic bands were stretched between the retraction apparatuses and the lip hanger based on the desired force. Nasal stents were added to the retention arms when the cleft width was reduced to less than 6 mm. CONCLUSION: The modified PNAM treatment enabled faster derotation of the premaxilla and earlier initiation of retraction. The prefabricated retraction apparatus and retention arm provided efficient PNAM for patients with BCLP.
