Abstract
The goal of the present study was to evaluate the effects of PNAM appliance and cheiloplasty on alveolar molding. Samples consisted of 16 unilateral cleft lip and palate infants (10 males and 6 female, mean age=37.0 days after birth, average alveolar cleft gap=10.46 mm), who were treated with PNAM appliances by one orthodontist and rotationadvancement cheiloplasty by one surgeon in Seoul National University Hospital. Average duration of alveolar molding treatment was 13.10 weeks and these patients were recalled at average 8.31 weeks after cheiloplasty. These patients´ models were obtained at initial visit (TO, mean age: 37.0±27.89 days after birth), after successful alveolar molding (Ti, mean age : 119.25±40.18 days after birth), and after cheilopasty (T2, mean age :190.81 ±42.78 days after birth). Seven linear and five angular variables were measured using 1 : 1 photometry and soft ware program(V-ceph. Cybermed, Seoul, Korea). Paired t-test was performed to investigate statistical significance at p<0.05 level.
lThe posterior parts of alveolar segments were the off; sbaourrus during alveolar molding treatment period and after cheiloplasty in infants.
2, The closure of cleft gap during alveolar nidding was usually due to backward bending of the whole pmt of the grenter segment.
3. Although forward growth of the greater segment was hindered by alveolar molding, it resumed after chefloplasty
.
A Wease of anterior inter-segment angle aAer cheiloplasty was due to the molding effect of the lip scar prie-ssure.
