Abstract
To assess and compare the precision and predictability of zygomatic implants in atrophic maxilla using conventional and dynamic navigation methods. This study was a randomized controlled clinical trial conducted in patients requiring zygomatic implant placements in the atrophic maxilla. Forty zygomatic implants were placed in systemically healthy individuals. Zygomatic implant placement was done using the freehand technique in the control group, and the test group involved implant placement using a dynamic navigation system, and the entry, apex, and angular deviations were evaluated. The mean deviations at the site of entry (2D) in the navigation system (2.531.42) as compared with the freehand (4.151.29) were statistically significant. The variation in the freehand group was greater than the navigation method at the apex (3D) (P < .05). The navigation method had a higher accuracy in angular deviation than the freehand method (4.02 ± 1.80 and 12.67 ± 2.11). Also, the accuracy was checked on the right and left sides in both the conventional and dynamic groups. The dynamic navigation technology had better predictability in terms of accuracy and precision, and it is the need of the hour for clinicians to master this technology and thereby aid in better prognostic level of implant placements.
