Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

general group

Intervention Type OTHER

The sample comprised maxillary and mandibular dental casts of 70 Caucasian Brazilian individuals (28 men and 42 women) with an average age of 16.4 years, all of which had natural normal occlusion with at least four of the six keys to normal occlusion. 14 The first item of the first key was considered essential for sample selection(Angle Class I molar relationship). Another inclusion criterion was that individuals should be at least 15 years of age with no odontogenic abnormalities and all permanent teeth in occlusion.
