Abstract Title of Thesis:The development and clinical application of composite archwire Major subject: stomatology Ph. 中 文 摘 要论文题目:复合矫治弓丝的开发研制与应用专 业:口腔医学作 者:朱宪春指导教师:欧阳喈 教授加速牙齿移动,缩短正畸疗程,已成为正畸临床研究的重要课题。
Objective To compare the effects of edgewise band with those of straight archwire band in using edgewise appliance. 目的观察在方丝弓矫正技术中应用直丝弓带环的临床治疗效果。
Japanese welded the NiTiSMA with SS to produce a composite archwire for orthodontic expansion at 1997. (3)对CoAW作用于错位牙上的力进行计算和分析;
It was explained how ART Auxiliary Arch is used clinically, including the clinical applying instances, choosing main archwire, procedure and adjustment. 结果ART辅弓可以有效地对上下颌前牙进行转矩控制,同时由于其独特的生物力学特点而产生加强下后牙支抗、打开咬合、远中直立磨牙等临床效果。
Up to now, the TiNi shape-memory alloy archwire(TiNiSMA) and Stainless Steel archwire (SS) materials are employed in clinical orthodontics not only in china but also in abroad. SS丝的刚度较大,可为支抗牙提供充足的支抗,但由于其弹性较小,对移动牙会产生过大矫治力,以至影响牙齿的移动。
