ABSTRACT

The purpose of this paper is to review the literature on the accuracy of static computer-guided surgery in implantology, starting from a summary of the evolution of implant-placement guidance systems and the importance of correctly positioning dental implants. Subsequently, we consider both the mean and the maximum deviations reported by recently published papers to assess the overall accuracy of such systems. The mean linear deviation is reported to be in the 1-1.63 mm range at the coronal centre of the implant or its apex, while the mean angular deviation is stated to be around 5-6°, suggesting greater precision of static computer-guided surgery if compared to free-hand positioning. At last, the need to better distinguish the factors influencing results is highlighted.
