ANGULAR MEASUREMENTS.

LI–CA: It is the angle formed by joining a line from Iii to Iia and corpus axis (CA). It evaluates the inclination of lower incisor in relation to corpus axis.

LI–APog: It is the angle formed by joining a line from Iii to Iia and point A to Pogonion. It defines the protrusion of mandibular anteriors.

LI–OP: It is the angle formed by joining a line from Iii to Iia and occlusal plane. It indicates the treatment induced change in inclination of mandibular incisor.

LM–CA: It is the angle formed by joining a line from L6 to L6mr and corpus axis (CA). It evaluates the angulation of lower molar in relation to corpus axis.

LM–OP: It is the angle formed by joining L6 to L6mr and occlusal plane. It indicates the treatment induced mesial or distal tipping of molar.

Ba-N–CA: It is the angle formed between two stable reference planes (Basion-Nasion and Corpus Axis). It was selected as an indicator of possible treatment-induced mandibular rotation.
