Malocclusion is a developmental condition. In most instances, malocclusion and dentofacial deformity are caused, not by some pathologic process, but by moderate distortions of normal development. More often these problems from a complex interaction among multiple factors that influence growth and development, and it is impossible to describe a specific etiologic factor.
The term “overbite” applies to the distance which the maxillary incisal margin closes vertically past the mandibular incisal margin, when the teeth are brought into habitual or centric occlusion.
The term “closed bite” or “deepbite” describes a condition of excessive overbite, where the vertical measurement between the maxillary and mandibular incisal margins is excessive when the mandible is brought into habitual or centric occlusion.
