Abstract
PNAM provides a safe, effective, and lasting improvement in the esthetics of the nasolabial complex in infants with CUCLP. The result is an overall improvement in esthetics and minimizing the extent of surgery and the number of surgical procedures, thus providing a positive psychological impact on the parents. The virtual method of designing and fabricating the NAM plate using modern technology, holds a lot of promise, as it eliminates the timeconsuming laboratory steps. Our study aimed to evaluate the use of 3D technology in comparison to the conventional method in rehabilitating neonates with CUCLP. Twenty neonates with non-syndromic complete unilateral cleft lip and palate CUCLP were grouped into two groups, the first group received conventional PNAM, and the second group received the CAD-NAM. Both NAM techniques decreased the gap distance of the cleft in both groups at T2 and similarly improved the nasal deformities. The CAD-NAM decreased the number of visits in comparison to conventional appliances. The design of the plates is simple but needs an experienced operator in addition to individualizing a precise 3D growth factor for the sequential production of the CAD-NAM appliances. So based on the limitation of this study it was concluded that: • The use of digital technology facilitated the design and production of presurgical orthopedics. • The addition of the nasal stent to the CAD-NAM was difficult for attaching the wire to the 3D-printed plates. • The use of the silicon-based soft-liner in the conventional group was limited by the width of the gap as in gaps more than 12 mm a new appliance was needed to be fabricated for the patient. • In both groups regarding the side effects from the plates, it was found that the intraoral irritation from the CAD -NAM was less than that in the case of the conventional NAM. • The guardians’ commitment to the treatment procedure was a must. • The CAD-NAM, although easier and decreased the number of visits, its cost in Egypt is very high in comparison to the conventional NAM.
