[Dorsal border of denture base after SR-Ivocap polymerization]

The amount of dorsal borderspace of upper-plates after polymerisating in different dental laboratories has been measured and compared by statistically methods. This result showed a conspicuously small deviation. The overall average was to be found in the range of only 227 microns +/- 10.5 microns after water-laging for 4 weeks. This amount is conformable to the results of Marx. There is no interpretation of the high values measured by Peroz recently. This present results confirm on the contrary the clinically verification of the SR-Ivocap-polymerisating equipment.
