摘　　要：采用3D打印技术与数字化医疗技术制造的无托槽隐形正畸矫治器,能为口腔错颌畸形患者提供个性化治疗.建立高仿真度的口腔上颌数字实体模型,采用状态非线性有限元分析法,获得隐形矫治器作用下双侧中切牙舌向平移0.35 mm时前牙相关组织的应力分布及位移趋势,最后通过电阻应变片测量法进行矫治力实验研究.The invisible orthodontic appliance without bracket manufactured by 3D printing technology and digital medical technology can provide personalized treatment for patients with oral malocclusion. A high simulation oral maxillary digital solid model was established, and the state nonlinear finite element analysis method was used to obtain the stress distribution and displacement trend of anterior teeth when the lingual translation of bilateral central incisors was 0.35 mm under the action of invisible appliance, finally, the experimental study of orthodontic force was carried out by measuring the resistance strain gage.
