Effects Of Removable Orthopedic Appliance On Upper Airway Dimensions, Yu-Jen Hsu, Stella Ya-Hui Yang, Emily Yi-Min Liu, Yi-Jane Chen, Wen-Chung Chang
Taiwanese Journal of Orthodontics
Growth modification by using removable orthopedic appliances has been commonly used in growing patients to correct maxilla-mandibular jaw discrepancy. Previous studies reported the different effects of various orthopedic appliances on the airway dimension. Low-pull headgear therapy may induce a short-term decrease of the upper airway dimension in Class II patients. Face mask therapy seems to be associated with the increase of upper airway dimension in growing Class III patients. However, mandible protruding appliances can increase the upper airway dimension, especially in the Class II patients with mandible retrusion.
Long-Term Follow Up Of Two-Stage Treatment Of Skeletal Class Ii Malocclusion – Case Report, Hui-I Chen, Hsiang-Min Hsu, Wen-Hui Hsieh
Long-Term Follow Up Of Two-Stage Treatment Of Skeletal Class Ii Malocclusion – Case Report, Hui-I Chen, Hsiang-Min Hsu, Wen-Hui Hsieh

The common treatment protocol for skeletal Class II malocclusion during mixed dentition is a two-stage treatment, namely functional appliance followed by fixed appliance. The goal of the functional appliance is to enhance the horizontal growth of mandible. After reevaluation, the second stage of fixed appliance is implemented. This is a 2-case report of skeletal Class II malocclusion. Both clinical examinations showed mandible retrognathia, large overjets and full Class II Angle’s molar relationships. Two-stage treatments were undertaken. After functional appliances, overjets were reduced and Class I molar relationships were achieved. Following that, fixed appliances were carried out without extraction of teeth …
The Treatment Of Skeletal Class Ii Malocclusion By Using Activator In The Circumpubertal Growth Period, Jeih-Fu Chen, Hong-Po Chang
The Treatment Of Skeletal Class Ii Malocclusion By Using Activator In The Circumpubertal Growth Period, Jeih-Fu Chen, Hong-Po Chang
Taiwanese Journal of Orthodontics
The treatment timing is the most important factor in the correction of skeletal Class II malocclusion. The treatment effect in contribution of mandibular growth in the circumpubertal growth period is better than that in the pre-pubertal growth period in use of no matter what kind of orthodontic appliance. This report is a case of skeletal Class II malocclusion with mandibular deficiency. By using functional appliance (Activator) and fixed orthodontic appliance in the circumpubertal growth period, the malocclusion and retruded mandibular profile had been successfully improved.
Correction Of Posterior Buccal Crossbite With Bionator, Yen-Chuang Lin, Bilin Spring Hsu, Sheng-Yang Lee
Correction Of Posterior Buccal Crossbite With Bionator, Yen-Chuang Lin, Bilin Spring Hsu, Sheng-Yang Lee

Functional appliance is often used for treatment of growing patients. If we can understand the device design and treatment mechanism of functional appliance, it can be applied to adult patients. The following text would review the functional matrix theory and composition of functional appliance, especially for the bionator. Finally, a case will be reported.
The Orthodontic Treatment In The Patient Of Angle’S Class Ii Relationship With Mandible Retrusion By Using Multiple Functional Appliances, Tzu-Yin Chen, Chun-Liang Kuo, Kai-Li Wang, Jhih-Wei Chen, Hui-Lin Chen
The Orthodontic Treatment In The Patient Of Angle’S Class Ii Relationship With Mandible Retrusion By Using Multiple Functional Appliances, Tzu-Yin Chen, Chun-Liang Kuo, Kai-Li Wang, Jhih-Wei Chen, Hui-Lin Chen
Taiwanese Journal of Orthodontics
The etiology of Angle’s Class II malocclusion are: 1.maxillary protrusion, 2.mandibular retrusion, 3.combination of both. The therapeutic methods of Angle’s Class II malocclusion with mandibular retrusion by using the functional appliance will correct neuromuscular dysfunction, remodeling of the glenoid fossa and enhancement of condyle growth by anterior positioning of mandible. In this case report will present a patient of Angle’s Class II malocclusion with mandibular retrusion. By using multiple functional appliances during active growth period to improve mandible forward positioned and the maxilla-mandible relation is altered. Then, combined with fixed orthodontic treatment, the convex profile and malocclusion is improved. Esthetics …
