Intraoral scans were taken shortly after birth, at the monthly checkups and just before the surgical cleft closure at approximately 6 months of age. Surface measurements of maxillary segments were conducted using the diagnostic program OnyxCeph\u00b3\u2122. For identifying the best fit for the growth pattern, mixed-effects regression models (fractional polynomials and B-splines) with the surface measurement as dependent variable, patient age (days) as predictor and the patient as random effect were fitted to the data. The best fit was selected according to the Akaike Information Criterium. A likelihood ratio test was performed for comparing the selected model with the intercept-only model.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>The linear regression with mixed effects model showed the best fit for the total area, the area of the large segment and the area of the small segment. A highly significant association between the surface area and patient age was observed (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). An increase of the area with time was estimated at 2.88 mm<jats:sup>2<\/jats:sup> per day for the total area, 1.62 mm<jats:sup>2<\/jats:sup> per day for the area of the large segment and 1.25 mm<jats:sup>2<\/jats:sup> per day for the area of the small segment.
