The goals of this study were 1) to present pre-surgical naso-alveolar molding(PNAM)
appliance for bilateral cleft lip and palate treatment and 2) To evaluate the effects of the
PNAM appliance on the alveolar molding of the premaxilla and the lateral segments.
Subjects consisted of 8 bilateral cleft lip and palate infants (7 males and 1 female,
mean age at first visit = 61.6 days after birth) who were treated with PNAM appliances
in Department of Orthodontics, Seoul National University Dental Hospital.
Average alveolar cleft gap between the premaxilla and lateral segment was 8.09¡¾
5.03mm and average duration of alveolar molding treatment was 8.8¡¾3.1weeks.
These patients' models were obtained at initial visit (T0) and after alveolar molding
(T1). 20 linear and 14 angular variables were measured by using photometry and digital
caliper. All statistical analyses were performed by Microsoft Excel 97 program. Paired
t-test was used to discriminate the effect of alveolar molding by PNAM appliance.
1. Closure of the alveolar cleft gap in bilateral cleft cases by molding therapy was
completed successfully.
2. Alveolar molding inhibited outward growth of lateral segments and produced inward
bending of lateral segments.
3. By bending the anterior part of the vomer, the premaxilla could be rotated and moved
posteriorly via alveolar molding.
Conclusion : This appliance can be applied to bilateral cleft lip and palate infants with
satisfactory result before cheiloplasty.
