Innovation Toward the Future (大會主題)(點入)

演講主題: effective maxillary protraction in CL III patients:looking into the future

●limitations of camouflage a CL III malocclusion

1)differential growth of the maxilla & mandible

2)facial esthetics

3)periodontal problems

演講中他有提到一種裝置叫hybid-hyrax appliance可以看下面這一篇文章裡頭有這種圖像↓

A Miniscrew System with Interchangeable Abutments 和這一篇

A Miniplate System for Improved Stability of Skeletal Anchorage

另外提到GTRV analysis,請看以下這幾篇

1,Prediction of Mandibular Growth using Growth Treatment Response Vector Analysis

2,An 8-year-old patient presents with an anterior crossbite and skeletal Class III malocclusion. How can I be sure that early orthopedic treatment will be successful?

GTRV = horizontal growth changes of the maxilla/horizontal growth changes of the mandible

inclination of the condylar head, the vertical maxillomandibular relationship
and the width of the mandibular arch could predict the success or failure of early Class III treatment

The use of serial radiographs and GTRV analysis may help clinicians to predict excessive mandibular growth in patients with Class III maloclussions and decide whether to camouflage the malocclusion or proceed with surgery

3,Early Timely Treatment of Class III Malocclusion

4,Early Treatment of Class III Patients To Improve Facial Aesthetics and Predict Future Growth

5.Growth: Is it a friend or foe(敵人) to orthodontic treatment?
