Objective: The objective of this study was to evaluate the effects of presurgical nasoalveolar molding (PNAM) therapy by standard Grayson technique (G1) and Yen Modification single step NAM technique (G2) on alveolar tissues in patients with unilateral cleft lip and palate (UCLP) using three-dimensional digital models. Materials and Methods: Totally, 10 patients with a mean age of 20 ± 16.07 days, having complete UCLP, were included in this prospective study. The maxillary plaster models were scanned. The study sample was divided into two group of 5 UCLP patients (G1 treated by standard Grayson technique and G2 treated by Yen Modification) for linear, angular, and area measurements before and after PNAM therapy. The distances between the identified landmarks were measured on the maxillary casts, and the distance and area measurements were performed using software Poly works (IIT Delhi). All subjects had undergone PNAM therapy for 3 months, the alveolar segments should have been approximated (≤5 mm), and the cleft width after PNAM should be reduced. Results: The decrease of the cleft width and arch length on the cleft side were significantly altered on the affected side (P < 0.005). No significant changes were observed when comparing both the groups using standard Grayson technique and Yen Modification single step NAM technique (G1 and G2). Conclusion: PNAM therapy effects mainly in the anterior alveolar segment and reduction of palatal and alveolar cleft width in patients with unilateral clefts of lip, alveolus, and palate in both Grayson and Yen Modification single step NAM technique. Both the Groups G1 and G2 suggested same treatment outcome in term of alveolar molding, but single step technique reduces patient's visits.
