中文摘要	目的利用无托槽隐形矫治微型测力实验平台,测量隐形矫治器矫治力的大小。方法搭建完整的隐形矫治力测量实验平台,测量矫治器戴入前后13个敏感单元压阻阻值的变化,推算应力,通过公式反算外力的大小,同时采用有限元模型进行分析验证。结果测量出芯片上13个测量敏感单元的压阻阻值,并计算得到全部13个应力测量敏感单元的应力状态,利用计算机和有限元分析软件反算外力,有限元模型仿真验证,结果基本吻合。结论本实验开发的无托槽隐形矫治微型测力系统的待定系数法基本正确,可以通过芯片上的受力推算出牙齿受到的外力。; Objective To develop a micro-stress sensor measurement system for invisible aligner based on siliconon-insulator( SOI) piezoresistive stress sensor and to measure the force magnitude of the invisible aligner. Methods The micro-stress sensor force measurement system was designed and built for invisible aligner. The resistance difference of the 13 sensor rosettes in the chip was measured before and after wearing the invisible aligner. The stress was calculated and the inverse force size formulated and analyzed by using the finite element module to simulate the results. Results The pressure resistance of the 13 sensor rosettes on the chip was measured and the stress status and the force inverse were obtained. The reverse force was caculated by computer and finite element analysis software and verified by finite element simulation model. The results were basically consistent. Conclusion The micro-stress sensor measurement system for invisible aligner developed in this study could be used for caculating the external force the teeth receive.
