OBJECTIVES. The aim of this study was to assess the accuracy of virtual pre-surgical planning in orthodontic surgery and to compare it with the accuracy of traditional protocols. MATERIALS AND METHODS. The study included 7 patients: 3 of them were subjected to a pre-surgical planning accord-ing to the virtual protocol; 4 patients were subjected to traditional surgical prediction. Three-dimensional scanning of the cast models was executed and the degree of discrepancy between set-ups and pre-surgical models was evaluated using a digital software. Moreover, the values of maximum positive deviation, maximum negative deviation, mean deviation, standard deviation given by the software for every superimposition were taken into consideration. RESULTS. The analysis of the considered values did not point out significant differences between the two planning methods. CONCLUSIONS. The study shows that the reliability of the tested planning protocols is comparable. The difference lies in the extent of obtainable information, the repeatability of the procedure and the speed of execution.
