[The application of Edgewise technique auxillary with extra oral anchorage and class III elastic in the treatment of bimaxillary protrusion.].

In the treatment of growing bimaxillary protrusion patients,Edgewise technique auxillary with extra oral anchorage and class III elastic help to improve the patient's chin shape,recover his beauty of lower facial part and get a good occlusion along with the growing of mandible.The purpose of this study is:analysis the force system in the treatment and evaluate the result of the treatment with some typical cases.

[The effect of iontophoresis on accelerating orthodontic tooth movement]

This paper reported that acceleration of tooth movement can be gained by submucosal injection of some kind of medicine.To avoid the pain caused by the injection,conventional drug administration was ameliorated in this study by adopting the method of ionophoresis rabibits were divided into 2 groups and the standard otthodontic appliances were placed in the lower incisors of all animals.The 2 groups were separately recieved submucosal iontophoresis and injection of 0.9% NaCl which served as control.The result showed that animals with iontophoresis,in whose periodontal pression side more osteoclasts were observed histologically,had gained rapider tooth movement than those with injections.

[The effect of EBCI Iontophoresis on orthodontic tooth movement in rabbits]

The purpose of this study was to observe the effect of EBC ionophoresis on increasing the rate of tooth movement in rabbits.21 rabbits,in whose lower incisors the standard orthodontic appliances were placed,were divided into 3 groups at rendom which separately received iontoporesis of EBC,iontophosesis and injection of physiological saline at the submucosal area of the lower incisors.The results showed that the animals with EBC iontophoresis obtained tooth movement rate of 4.275+/-0.1214(mm) and the animals with NaCl iontophoresis and injection were respectively 3.337+/-0.4626(mm) and 2.178+/-0.2922(mm).The histological observation had also found the evidence of the ability of EBC to stimulate osteoclasts in preiodontal pression side and osteoblasts in tension.This study suggested that iontophoresis of EBC could play an important role in reconstructing the periodontum and speeding the tooth movement in rabbits.
