Definition of Dentoalveolar Measurements

Maxillary anterior alveolar and basal height (MXAABH)	Distance between the midpoint of the alveolar meatus of the upper first incisor and the inter-section point between the palatal plane and the long axis of the upper first incisor
Maxillary posterior alveolar and basal height (MXPABH)	Distance between the midpoint of the alveolar meatus of the upper first molar and the inter-section point between the palatal plane and the long axis of the upper first molar
The inclination of the upper incisors (U1-PP)	Measured at the intersection of the long axis of the upper central incisor with the palatal plane
The inclination of Lower incisors (L1-MP)	Measured at the intersection of the long axis of the lower central incisor with the mandibular plane
Mandibular anterior alveolar and basal height (MdAABH)	Distance between the midpoint of the alveolar meatus of the lower first incisor and the inter-section point between the mandibular plane and the long axis of the lower first incisor
Mandibular posterior alveolar and basal height (MdPABH)	Distance between the midpoint of the alveolar meatus of the mandibular first molar and the intersection point between the mandibular plane and the long axis of the mandibular first molar
U1 Clinical Crown Length (U.1.L)	Distance between the midpoint of the cervical margin of the tooth and the midpoint of the incisal edge
L1 Clinical Crown Length (L.1.L)	Distance between the midpoint of the cervical margin of the tooth and the midpoint of the incisal edge
Curve of Spee	Perpendicular distance between the deepest cusp tip and a flat plane that was laid on top of the mandibular dental cast, touching the incisal edges of the central incisors and most distal cusp in the arch
U6 Clinical Crown Length (U.6.L)	Distance between the cervical margin of the tooth and the tip of the bucal cusp
L6 Clinical Crown Length (L.6. L)	Distance between the cervical margin of the tooth and the tip of the bucal cusp
