Abstract: Orthodontic appliances essentially include removable appliance， functional appliance and fixed appliance. Removable appliance， due to the fact that the teeth movement is not precise enough and due to its insufficient anchorage support， is hard to realize the quality and precision which could be reached by fixed appliance treatment;as a result， less and less removable appliance have been used recently.Functional appliances and techniques are mainly used in the phase one treatment in a two-stage treatment patient. It has mainly been used for skeletal Class II cases and it has achieved good results and large-scale application in China. Up till now， the fixed appliance and technique has become the most commonly used appliance and technique in clinic globally. Edgewise and Begg appliances and techniques are popularized in clinic， and also MBT straight wire technique and Tip-Edge straight wire technique has been brought into China， and they all have obvious features during application. Straight wire appliance and technique has become the mainstream in Chinese orthodontic clinic. It is equally important that the domestic production infrastructure is sufficient enough and the product quality is not inferior to those produced in foreign countries. The recent hot issues in orthodontic area include self-ligating appliance， implant anchorage， lingual technique and invisalign appliance. After more than 10 years’ devotion into the exploration and research， Professor Jiuxiang Lin has developed the new generation straight wire appliances， transmission straight wire appliance and technique. The researchers also put forward the new philosophy with hardware- transmission forces and transform effect， which has upgraded the transmission appliance and technique to a complete new system. One of the cutting edges of this kind of appliance and the technique is that， it merely uses simple and effective intro-oral anchorage and could effectively correct the skeletal malocclusion without surgery， especially the difficult skeletal class III cases in early permanent dentition.

Key words: self-ligating braket, skeletal malocclusion, implant anchorage, transmission adjustable appliance
