I. Introduction
Facial analysis is an essential component of determining the quality and structure of facial expressions, which is utilized in various applications such as detecting education levels [1]. Several studies have shown that a certain level of asymmetry can generate an unattractive image. However, there is no facial profile without some degree of asymmetry. The most common causes of facial asymmetry are dental diseases, jaw anomalies, hemifacial microsomia, trauma, infection, tumors, or bad habits [2]. Those causes could result in limited oral function, pain, or social disability [3].
