Dynamic implant navigation is a technique that has been developed to improve the accuracy of dental implant placement. Several studies have investigated the influence of Kennedy class and the number of implants on the accuracy of dynamic implant navigation.

Block et al. (2017) conducted a study comparing the accuracy of implant placement using dynamic navigation to static guides and freehand placement. They found that dynamic navigation achieved similar accuracy to static guides and was an improvement over freehand placement. This suggests that the use of dynamic navigation can help improve the accuracy of implant placement regardless of the Kennedy class or the number of implants.

Wu et al. (2020) also investigated the accuracy of dynamic navigation compared to static surgical guides for dental implant placement. They found that the implant site had no significant influence on the accuracy of dynamic navigation. This indicates that the Kennedy class, which determines the complexity of the case, may not have a significant impact on the accuracy of dynamic navigation.

In a randomized controlled clinical trial, Aydemir & Arısan (2019) compared the accuracy of dental implant placement using dynamic navigation to the freehand method. They found that the accuracy between the planned and placed implants inserted by the static surgical stents was extensively studied, but such studies are limited for the dynamic navigation system. This suggests that more research is needed to determine the influence of Kennedy class and the number of implants on the accuracy of dynamic navigation.

Chen et al. (2023) conducted an in vitro pilot study comparing the accuracy of a novel implant robot surgery and dynamic navigation system in dental implant surgery. They found that the dynamic navigation system improved the accuracy of the implant position, depth, and angle. This indicates that dynamic navigation can help achieve accurate implant placement regardless of the Kennedy class or the number of implants.

Overall, the available literature suggests that dynamic implant navigation can achieve accurate implant placement regardless of the Kennedy class or the number of implants. However, more research is needed to further investigate the influence of these factors on the accuracy of dynamic navigation.
