title: The face-form as a guide for the selection of maxillary central incisors.
abstract: The outline forms of both maxillary central incisor teeth were compared with the "actual" and "apparent" face-forms in 70 subjects, to determine whether a close similarity of face-forms and tooth forms exists, which would support the "law of harmony" method for the selection of replacement of teeth. The results of the investigation do not support the contention of Williams but rather invalidate this method of teeth selection because more than two-thirds of the individuals showed no similarity between face-form and incisor tooth form.
