Axis referral |  | X = Transverse Y = Occluso-gingival Z = Antero-posterior |
Points on model | Palate | Palate references area of 3 points (R1, R2, and R3) |
Canine | M = mesial point angle I = cusp tip D = distal point angle G = center of gingival surface at buccal | |
Second Premolar | B = buccal cusp MB = mesio-buccal point angle DB = disto-buccal point angle G = center of gingival surface at buccal | |
|  | First Molar | B = occlusal point of buccal groove MB = mesio-buccal cusp tip DB = disto-buccal cusp tip G = center of gingival surface at buccal |
Angulation on model | Tip | Angle between two B/I – G lines in YZ Axis |
