Nasoalveolar molding (NAM) is a recognized adjunctive therapy to primary cheiloplasty in patients with complete cleft lip and palate (CLP). The conventional technique can be time-consuming, costly, and requires experienced clinicians. Over the past decade, CAD/CAM technology has been employed to facilitate NAM therapy, showing promising results. This study introduces an individualized Digital NAM (iDNAM), a digital approach revolutionizing NAM treatment using CAD/CAM technology, and evaluates treatment outcomes. A 57-day-old infant with complete UCLP underwent intraoral and nasolabial scans, along with 3D photogrammetry. Open-source software was utilized for virtual alveolar segmentation and NAM plate design. iDNAM incorporates a nasal molding extension, introducing an innovative nasal stent activation protocol. Changes in alveolar and nasal morphology were compared between the initial and presurgery stages. After treatment with iDNAM, the alveolar cleft gap was reduced to 4.22 mm. Nostril height on the cleft side, columellar length, and nose projection increased by 0.98, 2.40, and 1.90 mm, respectively. The nasal base-columellar angle improved by 29.50 degrees. The results demonstrate a significant reduction in the alveolar cleft gap and improved nasal morphology, making iDNAM as an alternative to NAM therapy.
