The purpose of this study is to investigate the relation between the thickness of silicone film obtained by fitness test and the pressure distribution under the denture base. Fitness tests were made on the simulation models at various amount of loads, measuring the pressure by diaphragm pressure sensors.The results obtained were as follows : 1. Under the conditions of this experiment, pressure distribution during fitness test got constant within 60 seconds. 2. Pressure distribution was made more uniform at fitness test. 3. Correlation was observed between the pressure and the thickness of silicone film. 4. On Model 1, simulated hard mucose membrane, they had hyperbolic correlation, and onModel 2, medium hard mucose membrane, they had linear correlation. 5. On the simulation model with constant displaceability, regression coefficient was notlargely affected by the location of sensors. 6. Relation between the pressure and the thickness of silicone film affected by the location of displaceability. From the results described above, it was proved that the pressure distribution under the denture base could be estimated by the fitness test, and on the clinical judgement of fitness test,it is necessary to consider the difference and the location of displaceability of mucose membrane.
