【Abstract】 We have developed a new-typed computerized radiography cephalometrics and prediction system. It includes cephalometrics, growth prediction, orthopedics/orthodontics prediction and profile prediction. In this study, 47 lateral cephalograms were randornly selected to process a reliability test. The results showed the ttwo groups were in agreement on all of the 25 measurement index. The system is easier, quicker and less prone to error than traditional cephalometrics approach. It is convenient for orthodontists.更多还原
