Schematic representation of the vertical dimension for a physiological overbite (A) and the combination of skeletal and dentoalveolar deep bite (B). (A) Physiological vertical dimension; harmonious relation between the upper facial height (UFH 50%) and lower facial height (LFH 50%). (B) A skeletal and dentoalveolar deep bite because of the anterior rotation of the mandible and elongation of the front teeth. There is a decreased lower facial height (LFH 46%) compared to the upper face height (UFH 54%).
