The purpose of this study was to analyze the surface and centraltemperature of wax rims for recording neutral zone.
Three types of wax rim were used in this study. The width of them were 10 mm (sample S), 13 mm (sample M) and 15 mm (sample L). Temperature were measured with the following procedure. Wax rims were soaked into 47°C water for 3.0 minutes, 37°C water for 1.0 minute, then cooled in 10°C water for 2.0 minutes. This procedure was repeated three times. The surface and central temperature of wax rims were measured continuously by the thermosensor through all steps.
The results were obtained as follows:
1. In sample M and L, central temperature of wax rim was lower than surface temperature.
2. In sample S, cental temperature of wax rim was as high as surface temperature.
