Uniformity of palatal volume and surface area in various malocclusions

Abstract

The complex and multifactorial aetiology of malocclusion reflects the interplay between predominantly genetic factors and environmental influences. 1,2 The latter include localized effects in response to sustained impactful insults such as mouth breathing, sucking habits and abnormal swallowing and tongue activity. 3 The more commanding 'genetically determined' functions in the craniofacial complex (e.g. brain growth, respiration and muscle activity) are thought to direct the growth of the craniofacial skeleton. 4 The literature on the environmental influence is extensive and may be summarized in key findings. The dimensions of the palatal vault have been closely associated with oral functions and habits such as mouth breathing and thumbsucking. 5 A narrow maxillary

Comparison of three-dimensional reconstructed palatal morphology in skeletal Class III and skeletal Class I subjects with different vertical patterns

“…In skeletal Class subjects, both males and females, hyperdivergent subjects had a higher and narrower palate than hypodivergent subjects, which was consistent with the results of previous studies [8,11,[17][18]. Palaoni et al used GMM method and found that the vertical patterns had the greatest in uence on the palatal morphology in skeletal Class III subjects, and as the mandibular plane angle increased, the palate became higher and narrower [11].…”
