Abstract

Evaluation of Lingual Arch form among Angle Class I, Class Iiand Class III Malocclusions in Chinese Orthodontic Patients

Highlights

The aim of this study was to analyze and compare the dental lingual arch widths and lengths, alveolar arch within patients with Angle’s Class I (ACI), Class IIdivision1 (ACII) and Class III (ACIII) malocclusions in Chinese patients
Correct identification of a patient’s arch form is a crucial parameter in achieving a stable, functional and esthetic orthodontic treatment result, since failure to preserve the arch form might increase the probability of relapse[2]
Researchers introduced a new anatomic arch form technique in Lingual Orthodontics[5] and proposed the positioning of thicker bracket bases to allow the use of arch wires without offsets[6]

Summary

Introduction

The aim of this study was to analyze and compare the dental lingual arch widths and lengths, alveolar arch within patients with Angle’s Class I (ACI), Class IIdivision (ACII) and Class III (ACIII) malocclusions in Chinese patients. There are many confounding factors on measuring intercanine distances which hinder clinicians from determining the size of mushroom-shaped lingual arches To simplify this technique, researchers introduced a new anatomic arch form technique in Lingual Orthodontics[5] and proposed the positioning of thicker bracket bases to allow the use of arch wires without offsets[6]. Researchers introduced a new anatomic arch form technique in Lingual Orthodontics[5] and proposed the positioning of thicker bracket bases to allow the use of arch wires without offsets[6] They obtained arch form by the different method, some used the 3D digital imaging to obtain a three-dimensional structural model, and some adopted the teeth landmarks such as the tongue side of the center or crown cusp positioned, while others applied geometric curves to describe the dental arch[7,8,9,10]
