[Classification of crown forms. Morphological interrelationship between upper central incisors and facial forms].
The interrelationship between tooth forms and facial outlines is represented in multivariate linear combinations. Principal Component Analysis was used in this study as an expression of morphological features. Measured data on the tooth and the face could be classified into 4 types by the first and second principal components of multivariate analysis. Of the 117 subjects, the largest group of 33 (28.9%) had of oval faces and were Class III for the face and Class II for the teeth, respectively. Of the 117 subjects, 36 showed morphological similarity between teeth and face.
