摘　　要：目的:利用光弹树脂材料特性,研制能够直接简便观察咬合应力分布的咬合片,评价其应用效果。方法:使用自制硅橡胶阴模,浇注2种厚度、4种增塑剂比例配方的环氧树脂咬合片。选择10例天然牙列者、5例全口义齿牙列者,从软硬度、可咬性等方面对咬合片作主观评价,并用光弹仪观察各种咬合片咬合印迹,进行客观评价,最后与T-Scan系统进行比较。结果:2-50咬合片既有合适的咬合舒适度,又可清晰反映咬合印迹,与T-Scan检测结果具有可比性。结论:与传统咬合检查方法相比,光弹咬合片可以提供更直观的咬合应力分布信息,有助于咬合相关的疾病诊断和疗效评价。PURPOSE：To develop an occlusal film that can be intuitively and easily used clinically to observe the stress distribution of occlusion,based on the photoelastic resin material properties.METHODS：Using self-made silicone rubber vaginal mold,the epoxy resin occlusal films were poured into 2 different thickness and 4 different plasticizer ratio.The hardness and bitability were evaluated in 10 cases of natural dentition and 5 cases of complete denture dentition,while the bite blot was recorded using light bomb instrument at the same time.The data was analyzed and compared with T-Scan system.RESULTS：2-50 occlusal film presented not only a right bite comfort,but also a clear response to occlusion blotting,which showed a comparable manifestation with T-Scan system.CONCLUSIONS：Compared with traditional inspection methods,occlusal photoelastic film can provide more intuitive occlusal stress distribution and benefit the diagnosis and efficacy evaluation of bite-related diseases.
