Precision
For accurate dental castings a free and uniform expansion of the investment compound as well as a quick and tension free cooling after casting is very important. This can be achieved by creating an even layer of investment compound surrounding the objects and by reducing the volume of the investment at the same time. The spacers which are part of the OPTI-RING-SYSTEM are positioned accordingly for investing.
A short cooling phase reduces the oxide-layer of conventional dental alloys as well as the alpha-case formation when casting titanium. An abrasive, mechanical removal of these layers is minimalized. Results are more accurate castings.
Economical
Depending on the size of the cylinder and spacer being used up to 50-60% less investment compound is required.
