ORTHODONTIC LIMITATIONS
Angle – Class 1 molar Relation ship 1925 – 1945
Tweed – Lower Incisor Position 1945 –1985
Surgical influence – Upper incisors/positioning anterior 6 teeth

Cephalometrics – What Value ?
Measurements based on cranial base landmarks –inaccurate in defining clinical profile Disconnect between hard & soft
tissues! No measurement is 100% accurate Soft tissue thickness / axial
inclination of incisors – the most important variables in inaccuracy
Michels & Tourne Int J Adult orthod orthog Surg 1990 5 (1) 43-52www.indiandentalacademy.com
JCO Survey 99 – traditional Ceph Analysis used by 94% orthodontistsIs it a Problem ?• Measure skeletal and dental relationships• Measure to cranial base • Soft tissue/ profile correlation ?•Did we forget to reintegrate soft and hard tissues ??
