| Summary: | 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.
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.
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.
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. Supported by Research Fund of Science and Technology Commission o |
