A playground of secrets,a glory of function”

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
