Objective: To compare the effects of presurgical infant orthopedics using 2 different methods, that is, the Dynacleft with Nasal elevator system versus the modified Grayson’s technique in patients with complete unilateral cleft lip and palate. Design: Prospective comparative cohort study. Materials and Methods: Twenty-eight patients were divided into 2 groups, that is, Group A consisting of 14 patients who underwent correction with DynaCleft with Nasal elevator system and Group B consisting of 14 patients undergoing correction using the modified Grayson technique. Maxillary cast measurements were taken at 2-time intervals (pre- and posttreatment) to assess various parameters using a laser scanning machine (C500 Solutionix) and 3D software (GOM Inspect). Similarly, standardized anterior–posterior and worm’s-eye view photographs using a custom box were taken and imported to Adobe Photoshop CS6 for measurements. Paired t test and independent t test were used to compare intra- and intergroup changes, respectively. Results: The analysis of cast (primary outcome) and photographic (secondary outcome) measurements showed improved nasal asymmetry and alveolar correction in both groups which showed no significant intergroup difference when assessed using the independent t test ( P > .05). Group A showed higher chances (42.8%) of causing a T-shaped defect (due to excessive mesial-inward rotation of the minor segment) when compared to the Group B possibly due to a more controlled molding vector ( P < .05). Conclusion: Both methods proved effective in improving the nasal asymmetry, reducing the alveolar cleft gap, and approximating the lips together; but care must be taken when applying the alveolar molding vector in the Dynacleft system.
