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.
