“…The degree of asymmetry in anatomy may indicate a genetic (Boder, 1953 ; Cassidy et al, 1998 ; Lundstrӧm, 1961 ; Melnik, 1992 ; Moreira et al, 2008 ; Wolpert et al, 2006 ), congenital or acquired pathological condition (Bishara et al, 1994 ) as well as abnormal habits, such as finger sucking (Lundstrӧm, 1961 ; Reid & Price, 1984 ; Yamaguchi & Sueishi, 2003 ). Knowledge of difference between “normal asymmetry” (Functional) and “pathologic asymmetry” (Para‐functional) is important for diagnosis of medical conditions.…”

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.

“…Environmental pressures also play a role in the development of asymmetries. Some infants are born with facial asymmetries due to parturition pressures, but most studies have shown that asymmetries caused by birthing pressure only last for a few weeks to months before normal relationships of the facial and skull bones are restored (Boder 1953).…”

Iowa Department of Orthodontics for allowing me the opportunity to further my education and giving me the knowledge and tools to pursue a career in orthodontics. The great research projects of this department are reflection of their intelligence, dedication, and love for the art and science of orthodontics. Lastly, I would like to thank my friends and family for all their help and support. Their love and friendship helped me to stay energized and focused.
