“…Non‐nutritive sucking habits may result in the development of physiological imbalance during growth in addition to deviations from a normal swallowing pattern (Cozza et al, 2007 ; Katz et al, 2004 ; Melink et al, 2010 ; Vazquez‐Nava et al, 2006 ; Warren & Bishara, 2002 ) due to thumb‐sucking pressure (Yokota et al, 2007 ) and tongue anterior thrusting leading to longer‐term problems especially present in children (Melink et al, 2010 ; Vazquez‐Nava et al, 2006 ).…”

Objectives: Palate morphology is constantly changing throughout an individual's lifespan, yet its asymmetry during growth is still little understood. In this research, we focus on the study of palate morphology by using 3D geometric morphometric approaches to observe changes at different stages of life, and to quantify the impact of directional and fluctuating asymmetry on different areas at different growth stages. Materials and Methods:The sample consists of 183 individuals (1-72 years) from two identified human skeletal collections of 19th and early 20th Century Italian contexts. A 3D-template of 41 (semi)landmarks was applied on digital palate models to observe morphological variation during growth.Results: Asymmetrical components of the morphological structure appears multidirectional on the entire palate surface in individuals <2 years old and become oriented (opposite bilateral direction) between 2 and 6 years of age. Specifically, directional asymmetry differentially impacts palate morphology at different stages of growth. Both the anterior and posterior palate are affected by mild alterations in the first year of life, while between 2 and 6 years asymmetry is segregated in the anterior area, and moderate asymmetry affects the entire palatal surface up to 12 years of age. Our results show that stability of the masticatory system seems to be reached around 13-35 years first by females and then males. From 36 years on both sexes show similar asymmetry on the anterior area. Regarding fluctuating asymmetry, interindividual variability is mostly visible up to 12 years of age, after which only directional trends can be clearly observed at a group level.

“…After treatment, significant decrease in maxillary protraction (SNA angle) was obtained, since the palatal crib helps in relief the direct pressure on the anterior region of palate, which may reach to 4.52 kg (36) and considered larger than normal tongue pressure 1.57 kg (37) causing correction of protracted maxilla.…”

The aim of this clinical study was to cephalometrically investigate profile changes after using a palatal crib and fixed orthodontic appliance therapy, in children with thumb sucking. Fifteen females with age ranged from 8 to 10 years were used in this study, irrespective of the molar relationship. Lateral cephalometric X-ray films were taken before and after treatment, and sixteen variables were measured and statistically analyzed using a paired t-test. Before and after treatment differences were statistically significant for all variables except mandibular apical base relationship and maxillary length. Dentoalveolar changes were evidenced as retrusion and extrusion of incisors and decrease in the open bite and overjet .The dento-skeletal changes implied soft tissue changes in the form of retracted upper and lower lips , decreased interlabial gap, and increased nasolabial angle. On the basis of the data obtained it could be concluded that the break of the habit allow skeleto-dental and soft tissue improvement, and early intervention of thumb sucking are essential to re-establish the adequate growth and development potential.
