Fig. 7. Three-dimensional positional relationship between the dentition and underlying basal bone in the Class I and Class II groups in females. The x-axis represents the horizontal distribution, and y-axis represents the vertical distribution of the dental arch and basal bone region. Red: central incisor; orange: lateral incisor; yellow: canine; green: first premolar; cyan: second premolar; blue: first molar; purple: second molar; grey plane: basal bone plane. A, Three-dimensional positional relationship for the maxilla. B, Three-dimensional positional relationship for the mandible.
