The IGI Advantage
IGI is more accurate than using drill sleeves
IGI is better for narrow interproximal spaces.
Accuracy Verification during Surgery
The surgeon can change the plan in the middle of the procedure.
Results are precise and consistent.
Shortened procedure time
Less stress for the doctor.
Time-effective immediate implant loading:
Fabricate the immediate restoration in advance and save valuable post surgery time
Use the IGI prior to patient surgery to create an accurate working model with the pre-planned positions of the implants.
Faster Implant Integration
The osteotomy is almost a perfect circle with no need to change angulation while drilling.
The surgeon can get low torque (25Ncm) upon insertion with a very high Osstell reading of 80.
This is the best system to use in larger cases like the All on 4 since the plan can be easily modified; including those for the posterior angulated implants.
IGI is cost effective
Consumables cost about $25 per arch
Stents are reusable for future implants on the same arch
Can be used to locate calcified canals during endo
IGI allows reproducing the same implant positions with the patient – the prefabricated restoration is easily adapted and immediately loaded!
Case studies and research
Published research
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.

Testimonials
patient w/ a small mouth. I previously had a surgical guide made from Nobel
but couldn’t use it because the guided drills couldn’t fit in the patient’s
mouth. I placed a total of six implants using the IGI. Surgery was done
flapless.
You can see here the advantages of using an image guided system as compared
to a conventional surgical guide. The time its takes to do the IGI surgery
is about the same time it takes to do it with a conventional surgical guide.
In challenging cases like this the IGI will be faster because you don’t have
to deal with the drills being too long.
