Three-dimensional evaluation of the maxillary arch and palate in unilateral cleft lip and palate subjects using digital dental casts

Abstract

Three-dimensional evaluation of the maxillary arch and palate highlighted significant differences between UCLP and non-UCLP subjects in mixed dentition phase, suggesting that orthopaedic maxillary expansion is advisable in UCLP.

Palatal morphology in unilateral cleft lip and palate patients: Association with infant cleft dimensions and timing of hard palate repair

“…In a previous study assessing occlusal differences between the two surgical groups and the association of occlusal scores with cleft dimensions at birth, we found a higher number of dental crossbites in EHPC than in DHPC, corroborating the results of the present study (Botticelli et al ysubmitted). From the orthodontic point of view, the results of the present study confirm the need for palatal expansion in both clefts groups and suggest that this need is even higher for those patients whose hard palate was closed early. Previous studies of the effect of early treatment of skeletal crossbite suggest a positive association between expansion and an increase of palatal volume …”

“…It has been previously shown how the development of recent 3D imaging techniques like mirroring and alignment/registration with geometric morphometrics (GMM) and principal component analysis (PCA) allows description of palatal volume and 3D shape analysis of the palate to identify patterns for specific malocclusions . Asymmetries in transversal dimensions and shapes of the palatal volume have been illustrated with simpler methods in cleft and non‐cleft crossbite patients, and the influence of oral breathing habits on palatal height has been elucidated through differences in palatal volume and shape …”

Evaluation of Maxillary Dental Arch Widths in Individuals Having Unilateral and Bilateral Cleft Lip and Palate Using Three-Dimensional Digital Models

“…The upper arch morphology of CLP patients are examined mainly by using conventional two dimensional (2D) dental casts analysis measured by directly and conventionally with digital calipers, which is a time consuming method with a limitation in providing reliable volumetric data. Some studies used 3D analysis for evaluating the upper ach dimensions in patients with CLP and comparison of arch widths were generally performed between untreated CLP patients and controls who were in the deciduous dentition [14] [16] [18].…”

Arch variation in relatives of individuals with orofacial clefts using 3D dental casts

“…Their findings were that intercanine widths were significantly smaller, but intermolar widths had no significant differences compared to controls. Palatal area and volumes were also significantly smaller than that of controls (Generali et al, 2017). These images can be found under Figure 1 by use of 3 Shape R700 laser scanner .…”

“…With purely extra-oral information developed so far in the studies of unaffected relatives of CL/P, the aim of this review is to use this new 3-dimensional technology to expand on the phenotypic spectrum of the unaffected relatives of patients with CL/P intra-orally.
