Abstract: PURPOSE: To evaluate the accuracy and operation time of domestic digital dynamic navigation and digital static guide in oral implant surgery. METHODS: Patients who were subjected to implant surgery at Department of Implantology, Affiliated Hospital of Qingdao University from September, 2018 to December, 2019 were selected. The patients were randomly divided into digital dynamic navigation group (n=21) and static guide group (n=19). The operation time of 2 groups was recorded, the linear deviation of the entry, apex point and angle in 2 groups were measured as well. The data was statistically analyzed using SPSS 25.0 software package. RESULTS: The average operation time of group 1 was 23.2 min, and that of group 2 was 14.5 min. The mean (SD) discrepancies of group 1 were (0.74±0.3) mm for entry point and (0.78±0.31) mm at the apex, the mean angle discrepancy was (2.45±1.26)° from actual vs planned implant positions. The mean (SD) discrepancies of group 2 were (0.79±0.39) mm for entry point and (0.78±0.35) mm at the apex, the mean angle discrepancy was (2.44±1.07)° from actual vs planned implant positions. There was no significant difference between the 2 groups in the measurement of the entry, apex point and angle of implants(P>0.05). CONCLUSIONS: There is no significant difference between the domestic dynamic navigation system and the static guide in the accuracy of assisting oral implant surgery. The operation time of the former in single tooth loss cases is longer than that of the latter. The indications of dynamic navigation are wider than that of static navigation, and need to be chosen according to specific conditions.
