RW-splint在安氏Ⅱ类1分类错畸形诊断设计中的应用
Application of RW-splint in clinical diagnosis of classⅡ1 malocclusion patients
摘要
Abstract
Objective To investigate whether the RW-splint could be used to guide or determine the CR position of the lower jaw so as to provide help for the later diagnostic design. Methods 20 classⅡⅠmalocclusion patients were recruited in orthodontic department of Foshan Stomatological Hospital. They were treated by RW-splint for half a year before orthodontic treatment. The overjet of anterior teeth were recorded before and after treatment. Results The over-jet of anterior teeth was (6.792 ± 0.795) mm before treatment and (7.720 ± 0.930) mm after half a year's treatment. The overjet of anterior teeth had significant difference (t=6.319, P<0.01). The overjet change of anterior teeth between be-fore treatment and half year after treatment was (0.928 ± 0.657) mm. Conclusion The RW-splint wearing before treat-ment can be used to guide or determine the mandible in the CR position.关键词
