“…However, findings from an earlier study showed that we had overestimated maxillary growth, so the resulting feeding plates had to be corrected manually by grinding or, in some cases, even reprinted, making the present investigation necessary (Ritschl et al, ). CAD/CAM‐assisted feeding plates have been described as suitable and promising for clinical application in CLP treatment (Shen et al, ; Ritschl et al, ; Yao et al, ). For a completely automated production based on only one initial impression‐taking, the natural expansion of the maxilla, palate, and alveolar ridge during the growth process must be considered to avoid unwanted events such as ulceration and growth restriction (Loeffelbein et al, ).…”

“…A feeding plate was virtually designed on the basis of an initial impression‐taking. The methods of additive manufacturing were used for plate production, as previously described (Ritschl et al, ). For the following months of treatment, further plates with increasing sizes were created using the percentile growth determined in this study.…”

This study describes the dentoalveolar and palatal growth during the first months of life. Knowledge concerning this development is essential to avoid unwanted events such as mucosal ulcerations or restriction of growth when cleft-lip and palate (CLP) patients are treated. The results involve the generation of CAD/CAM CLP-feeding plates. Intraoral impressions from 32 healthy newborns were taken monthly for 5 months, supplemented by measurements of body weight, length, and occipital-frontal head circumference. The casts were digitalized, and two observers manually selected defined anatomical landmarks on virtual 3-D models. The distances between these landmarks were evaluted. Statistical analysis included an inter-rater agreement analysis and the determination of growth. In total, 213 casts were analyzed, with 65 models excluded because of inaccuracies in impression-taking or cast production. Overall longitudinal growth was 20.3%, whereas transversal growth reached a maximum of 21.1%. Vertical growth was 32.4% at the tuberal level. On the basis of these results, a semiautomated series of feeding plates allowing for monthly expansion could be generated. The acquired data serve as a useful reference for other pediatric and orthofacial investigations and treatments. One such application is the automated, fully virtual manufacture of CLP-feeding plates based on only one impression-taking. Our data reveal when caution is needed to prevent ulceration. The series of plates generated can minimize the time-consuming impression-taking and the production of further plaster models. The method of measurement is suitable for documentary purposes. Clin.

INTRODUCTION: Cleft lip and palate (CLP) affects about 1.5 per 1000 live births (250,000 new cases per year) worldwide. They can be either unilateral or bilateral, complete or incomplete. The bilateral cleft lip and palate (BCLP) deformity typically arises with a protrusive premaxilla. The nasal deformity includes deficient columella, with flared lateral alar cartilages which usually require additional surgeries to improve the nasal symmetry. NasoAlveolar Moulding (NAM) technique, aims to align the alveolus, lip, and nose properly; reduce the severity of the nasal deformity, and lengthen the columella without surgery. OBJECTIVES: The study aims to quantify the effect of NAM therapy, fabricated by CAD/CAM additive manufacturing, in the improvement of nasolabial deformity in terms of bialar width, columellar length and width in infants with complete BCLP. MATERIALS AND METHODS: Ten infants with non-syndromic BCLP (age < 1 month) were selected. Impressions were obtained. The casts obtained from the impressions were scanned using a 3D laser scanner. Designing and 3D printing of the appliances were completed. The appliances were inserted and retained using surgical tapes. Nasal stents were incorporated 60 days after the start of the treatment. Nasal measurements were obtained before treatment and at the end of treatment (after four months). RESULTS: Data was collected and statistically analyzed. After NAM therapy, there was a statistically significant increase in columellar length and a statistically significant decrease in both columellar width and bialar width. CONCLUSIONS: CAD/CAM PNAM therapy has proved its effectiveness in BCLP by showing an improvement in the columellar and bialar presurgical presentation. CAD/CAM PNAM therapy should be considered a routine procedure in the treatment protocol for BCLP.
