1 This article demonstrated the usefulness of a non-contact 3-dimensional 2 (3D) morphometric apparatus in orthodontic diagnosis and treatment evaluation. 3 A female patient, 23 years 6 months of age, had a Class III malocclusion with 4 mandibular deviation. The 3D images taken by a 3D morphometric apparatus 5 figured out her protrusive chin of 6 mm on the deviation side compared to the 6 non-deviation side, and showed a possibility of orthognathic surgery.

The 3D images retaken for quantitative 9 evaluation showed decrease of the mandibular protrusion by approximately 3 mm, 10 and improvement of facial asymmetry. Then, we decided to treat the patient 11 without orthognathic surgery. After 18 months of active orthodontic treatment with 12 miniscrew anchorage, the mandibular deviation was improved and an acceptable 13 occlusion was achieved. The 3D images at posttreatment demonstrated 14 significant decrease of chin protrusion on the deviation side, and improvement of 15 facial asymmetry. In conclusion, a 3D morphometric apparatus could provide 16 quantitative data of facial asymmetry and chin protrusion and contributed 17 decision making process of treatment planning in a patient with facial asymmetry. 18 3 Introduction 1
