Summary

This study aims to determine the shape and dimension of dental arches from a lingual perspective, and determine shape and size used for lingual Orthodontics.

Detailed description

The study sample comprised 70 Caucasian Brazilian individuals with normal occlusion and at least four of Andrew's six keys. Maxillary and mandibular dental casts were digitized (3D) and the images were analyzed by Delcam Power SHAPET 2010 software. Landmarks on the lingual surface of teeth were selected to determine the shape and size of dental arches.

Conditions

• Dental Arch Relationship Anomaly
