title: [Preliminary development of photoelastic resin occlusal film].
abstract: OBJECTIVE
  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.
