Character introduction
DDS, PhD, Chief Physician, graduated from Peking University School of Stomatology. Visiting scholar in School of Dentistry, University of California, San Francisco from 2012 to 2014.
Currently she is deputy director of Department of Stomatology at Peking University 3rd Hospital. She is committee member of  Chinese Orthodontic Society (COS), Chinese Medical Association; standing committee member of Orthodontic Committee, Beijing Stomatology Association; committee member of Stomatology Group of Sleep Medicine Committee, Chinese Medical Doctor Association; committee member of Sleep Medicine Committee, China International Exchange and Promotion Association for Medical and Healthcare; editorial board member of Chinese Journal of Orthodontics. 
She has more than ten publications in orthodontic field; her research focuses on the Mechanism, Diagnosis and Treatment of Malocclusion, and the Relationship between Orthodontics, Occlusion and the TMJ joint. Her expertise is on adult orthodontics, multidisciplinary occlusion reconstruction, growth modification treatment, oral appliance treatment for OSAS.
Abstract
Topic: Craniomandibular Orthodontic Ttreatment of TMJDS Patients under the Guidance of VieSID Occlusion Concept

VieSID Concept is the occlusal concept of Vienna School of Interdisciplinary Dentistry, is established by Professor Slavicek from School of Dentistry, Vienna University in Austria. Compared with other traditional occlusion concepts, this concept has the following characteristics: 1. It intensively and precisely defined occlusal guidance system, put an emphasizes on a canine dominated sequential guidance on lateral mandibular movement, proposed a reasonable range for Anterior Guidance, and defined Retrusive Control for backward mandibular movement. 2. The concept of Reference Position (RP, in comparison with Centric Relation in other occlusal concept) is introduced, which is taken as the starting point of diagnosis. 3. Emphasize on the potent ability of TMJ to adapt, reconstruct and repair, and take advantage of joint compensation to achieve treatment goals.
Based on VieSID Concept, Professor Sadao Sato from School of Dental Sciences, Kanagawa University, Japan, proposed a treatment method called "Craniomandibular Orthodontics". Craniomandibular Orthodontics regards the masticatory organ as a functional unit, taking advantage of the adaptive compensatory ability of the organism to adjust the position of the mandible relative to the craniomaxillary complex in three-dimensional space in order to achieve 1, Aesthetic and stable static occlusion. 2. Smooth and comfortable functional movement. 3. Reasonable load of teeth and TMJ. Compared with traditional orthodontics, Craniomandibular Orthodontics focuses on improving the oral function of patients, adjusting the functional load of joints and teeth to prolong the life span of occlusion, and avoid orthodontic extraction and orthognathic surgery as far as possible.
Temperomandibular joint and occlusion are closely related in anatomy and function. Any change of occlusion may affect the functional state of TMJ through neural muscular system (NMS). Orthodontic treatment is a treatment to change occlusion. Therefore, the structure and function of TMJ is an indispensable topic in orthodontic treatment. Whether orthodontic treatment can cause TMJDS, or improve the symptoms of TMJDS, how to carry out orthodontic treatment for patients with TMJDS are problems that puzzle many orthodontists. This report describes the process of craniomandibular orthodontic treatment in two patients with TMJDS. The changes of occlusion, skeletal pattern, condylar movement, CT and MRI of TMJ before and after treatment were compared to provide new ideas for the correction of this kind of patients.
