Abstract
The purpose of this study was to find out the prope time and degree of adjustment for removable partial dentures using konus retainers.
Experimental dentures were placed in 4 subjects and set to a height of 100μm. They were then measured for longitudinal and vertical displacement by a fixed microgap sensor placed within the oral cavity.
The results were as follows:
1) During a 7 day period, the vertical displacement was measured to be 71.5μm as an average.
2) A large displacement was observed in those dentures between the time of insertion to the 4th day.
The results of this study suggest that the denture using konus retainers was able to settle into proper position after a few days. It is thus advisable to allow a few days for readjustment after insertion.
