摘　　要：目的:介绍带弹簧多用途唇弓的结构原理和临床应用,为正畸治疗提供一种选择。方法:介绍带弹簧多用途唇弓结构特点和临床适应证,并对结合该方法治疗的1例轻度骨性成年反牙合病例进行临床讨论。结果:治疗结束时,患者的侧貌有明显改善。头影测量结果显示:治疗前后SNA增加2°,SNB降低1°,ANB增加3°,U1NA增加1°,L1NB增加3°。结论:带弹簧多用途唇弓能持续、稳定地扩展前段牙弓。Objective:To introduce the clinical application of the coil-spring utility arch for orthodontic treatment. Methods:A 35-year-old male patient with mild skeletal anterior crossbite was treated by fixed appliance combined with coil-spring utility arch for 16 months. Cephalometric analysis was conducted before and after treatment.Results:After treatment, the patient's appearance was improved,and the cephalometric analysis showed that SNA increased by 2°,SNB decreased by 1°,ANB increased by 3°,U1-NA increased by 1°,L1-NB increased by 3°.Conclusion:Coil-spring utility arch can expand anterior dental arch continuously and stably.
