Computer Assisted Implant Surgery (CAIS) can help us achieve highly precise implant placement and that is by now a fact well established by more than 200 clinical trials. Either as static or dynamic, guided implant surgery can reduce the deviation of the implant platform at placement to about 1mm or less on average as has been assessed in multiple clinical scenarios from single implant to fully edentulous patients.
Although CAIS has significantly improved accuracy of implant placement in comparison to freehand surgery, neither static nor dynamic have completely eliminated errors. However, as static and dynamic CAIS systems utilise very different technologies and workflow, it becomes apparent that each has its own limitations and suffers from different sources of error.
We conducted a randomised clinical trial with 120 patients who received a single implant each. All implants were planned virtually in the same way, then patients were randomized in 4 groups: Static alone, Dynamic alone, Static and Dynamic combined and a Control group, where the implant was placed freehand.
The final result: combining static and dynamic CAIS lead to the smallest deviation recorded so far a mean 3D platform deviation of 0.62 ± 0.50mm, which was some 40% less than the average 1 mm we could get with static or dynamic alone. In terms of angle, the mean was 1.24 ± 1.41, which was about half of the average 3o that static or dynamic alone would offer. Maybe the most important was actually to study the frequencies, rather than the average, and there one could see that the combined static and dynamic had achieved a significant portion of the placements with an ultra high accuracy, at least when compared to other methods.
