A prospective clinical trial of the effects produced by the extrusion arch in the treatment of anterior open bite.

Aim: To evaluate the maxillary dentition effects of the extrusion arch for anterior open bite (AOB) correction in mixed dentition patients.

Materials And Methods: Fourteen subjects with an initial mean age of 9.17 ± 1.

Influence of maxillary canine torque variations on the perception of smile esthetics among orthodontists and laypersons.

Objective: The purpose of this study was to determine the perception of smile esthetics among orthodontists and laypersons with respect to unilateral maxillary canine torque variations in a frontal smile analysis.

Methods: Full face and close-up smile photographs of two subjects (1 man and 1 woman) were used. Both smiles displayed healthy maxillary anterior dentitions.
