摘　　要：目的探讨建立单侧上颌骨缺损的三维光弹模型的方法。方法利用标准牙体和上颌模型,建立单侧上颌骨缺损的硅橡胶阴模后,制作单侧上颌骨缺损环氧树脂光弹模型。结果制作完成环氧树脂单侧上颌骨缺损模型,环氧树脂牙体、牙槽骨和硅橡胶(牙周膜)弹性模量比值为13.3∶1∶0.001,与临床比值接近。结论建立的单侧上颌骨缺损的环氧树脂光弹模型光学灵敏度高,直观性强,能很好的满足光弹实验的要求。Objective Study the methods of establishing 3D photo-elastic model for unilateral maxillary defects. Method Unilateral maxillarydefects epoxymodel was made according to the silicone impression model of unilateral maxillary defects made by using standard tooth and maxillary model. Result Epoxy unilateral man- dibular defects model was developed. The ratio of epoxy resin teeth, alveolar bone and silicone rubber （PDL） elastic modulus was 13.3：1 ： 0.001, which is close to the clinical condition. Conclusions This epoxy-optical model of unilateral ma）dllary defects with high sensitivity and visual acuity could well meet the demand of the photoelastic experiments.
