OBJECTIVE: This study evaluated the effectiveness of computer-aided design-nasoalveolar molding (CAD-NAM) on maxillary alveolar morphology in infants with unilateral cleft lip and palate (UCLP).
METHODS: 15 infants with UCLP treated by CAD-NAM therapy composed the treatment group, and the control group consisted of 15 infants with non-presurgically treated UCLP. The maxillary morphology was analyzed by Rapidform XOR3 software. Differences in all variables pre- and post-CAD-NAM were discussed.
RESULTS: Significant difference was found in arch length, cleft gap, labial frenum deviation, A-X, A'-X, and alveolus height on both sides pre- and post-CAD-NAM.
CONCLUSIONS: This study suggests a trend toward morphological improvement in maxillary alveoli of infants with UCLP treated with CAD-NAM. The CAD-NAM effectively reduced the cleft gap, corrected the maxilla midline, and improved the sagittal length of the maxilla. The alveolar height decreased significantly after the treatment, which indicated that the traction force of the appliance may have obstructive effects on the vertical growth of the alveolar bone.
