IGI ACCURACY:
The accuracy of the navigation provided by the IGI was found to average 0.35mm.

ACCURACY APEX & ANGLE:
Scientific and clinical investigations carried out on patients confirmed a mean linear accuracy of implant positioning in the IGI system which was less than 1 mm on the level of the implant neck and its apex and mean angular deviation was less than 4 degrees on condition that implantation was unrestricted by surgical templates equipped with faucets for implant insertion [22,23].

ALL ASPECTS:
[W]e can conclude that the optical active navigation system is a unique tool which allows the
surgeon to evaluate the diagnosis and prepare virtual simulation of all aspects of implantological treatment. Due to a precise planning of the whole treatment, the realization of the surgical protocol in a detailed and safe way becomes possible.

TEMPLATE LIMITATIONS:
In the case of indirect navigation, the use of templates limits a surgical procedure and
the surgeon is not able to make any modifications [19-21]

MATCH PLAN AND FINAL IMPLANT:
IGI accuracy has been validated with real patients: This concept has been illustrated
in a recent study by Elian et at who studied the accuracy level in placing implants by the IGI.(7)
The mean linear accuracy was less than 1mm at both the implant neck and apical tip and the
reported mean angular deviation was less than 4 degrees. Despite the fact that all implants
were drilled free handedly and not through sleeves, Elian et al found an accurate match
between the planned implant and final implant.
A major part of the error could be attributed to human error in following the onscreen drilling path. In that context the important advantage of real-time navigation is that even when the actual free handed drilling is deviating from the planned drilling path the surgeon can still monitor the actual drilling onscreen. This accurate and immediate feedback allows the surgeon to judge whether the actual drilling path is clinically acceptable or should be corrected.
