Abstract
A three dimensional measurement system by 35mm non-metric SLR camera was developed (Part 1).
The purpose of this study was to examine the propriety of the application of the above mentioned system with addition of one other instrument, for clinical prosthodontics, especially in the measurement of complete denture base surface area.
In this experiment, three dimensional concave and convex curved metal test pieces were used to evaluate the accuracy of measuring curved surface.
Additionally, this system was applied to the measurement of complete denture base surface area and edenturous cast model surface.
And then the measurements were compared with one previous measurement system for accuracy.
From the three dimensional data obtained from this system, three dimensional color photographic representations of measured objects were also attempted.
Results were as follows:
1. Measurement errors of the test piece surfaces were -1.6% on the average.
2. This system was applicable to measure the denture base surface area.
3. Measured objects could be represented by three dimensional color photographs (Photo. 6-11).
