Tweeds analysis of Nepalese people.

The aim of the present study was to establish the Tweed's norms for Nepalese people, compare the values between the Nepalese male and female samples as well as to compare with the Caucasians. One hundred lateral cephalogram was taken by the same x- ray technician and later traced by manually and all three angular parameters Frankfort Mandibular plane Angle (FMA), Frankfort Mandibular Incisal Angle (FMIA), Inciso Mandibular Plane Angle (IMPA) were measured and found to be 28 degrees, 56 degrees and 96 degrees respectively. There was no clinical significant different between Nepalese male and female but there is highly significant among Nepalese and Caucasian.
