Adults with Different Vertical Bone Surface Fangs Far in Root Absorption Effect
Abstract：Objective To analyze the change of the tooth crown root ratio before and after the treatment of adult tooth extraction , and to investigate the influence of different type vertical bone surface of teeth .Methods According to a requirement to collect 100 patients with fixed straight O-PAK silk bow treatments , the experimental group was divided into high Angle , low Angle and Angle of both type three cat-egories , according to the mandibular plane Angle .Results Two experiment groups showed a statistically significant compared with the con-trol group;the Experiment 2 was not statistically significant compared with control group .After comparing the two , three groups all had differences , which was the low Angle >all Angle >high Angle.Conclusion In the orthodontic treatment , different vertical bone surface affects pointed fang root absorption and also affects root absorption moving distance .
