摘要： 目的探讨下颌第一磨牙半切术后光弹模型的设计和制作。方法根据相似性原理,用不同材料制作包含牙体、牙槽骨、牙周膜的第一磨牙半切术后下颌光弹模型。结果制作出几何形状、物理参数和边界条件与实体接近的下颌第一磨牙半切术后牙体及牙周支持组织的光弹模型。结论该光弹模型可用于对下颌第一磨牙半切术后牙周支持组织应力分布的定性分析。

Abstract: ObjectiveTo discuss the design and fabrication of the photoelastic model of mandibular first molar after hemisection.MethodsAccording to principles of similarity, different materials were used to manufacture the photoelastic model of mandibular first molar with hemisection, which included teeth, alveolar bone and pericementum.ResultsThe photoelastic modle of mandibular first molar with hemisection was manufactured, which was as similar as noumenon in appearance, parameter and boundary condition.ConclusionThe photoelastic model can be applied in qualitative analysis of the stress distribution in the periodontal supporting tissues of mandibular first molar with hemisection.
