Abstract
The Mixed Dentition Analyzer was invented to perform the space analysis of mixed dentition. It was computerized to utilize the regression equation by Ono (1960) andMoyers' probability at the 75% level for estimating the size of the unerupted cuspids and bicuspids.
In this paper, we described the operational procedure of this equipment, and then evaluated the measurement error between this method with the Mixed Dentition Analyzer and the conventional method with the mannual caliper.
The result was that the values estimated between both methods were nearly similar each other.The greatest advantage of this method might be that it spares the time required to perform space analysis. The application of the Mixed Dentition Analyzer appears to be practical for clinical use.
