Abstract
The following is a list of the test results using the three dimensional measurement system to measure a denture base as compared to the method used up until now.
1. The new measuring method is a remarkable improvement upon the measuring method used up until now.
2. The new measuring method takes about one fourth the time to measure as compared to the method used up until now.
3. The precision obtained using the new measuring system will not change much with experience.
4. Using the new method, measuring precision of the X axis direction was 5μm, the Y axis direction was 5μm, and the Z axis direction was 1μm.
