Placement of endosteal implants is a widespread therapy for re-establishing full functionality in edentulous patients. As
a first application of VISIT, a modular software system for research into computer-aided surgery developed at our hospital,
we have implemented a navigation system for computer-aided implant dentistry (CAID). Besides improved accuracy, benefits of
CAID include fast translation of preoperative imaging to the operating theatre and the possibility to insert the implants
without having to prepare large mucosa flaps. In this cadaver study, we have measured the overall accuracy of VISIT for inserting
four intraforaminal implants in the edentulous mandible. Five cadaver mandibles were embedded into plaster. After high-resolution
CT scanning, the mandibles were registered, and the implant channels were drilled by the surgeon. Training implants were inserted
into the implant channels, and the plaster was removed. Again, the mandibles underwent CT scanning, and the pre- and postoperative
scans were registered relative to each other. A gross registration between pre- and postoperative scans was achieved using
surface- or mutual information matching since in some cases the fiducial markers were lost. After transformation to a common
coordinate system, the accuracy was assessed by measuring the distance of the implant’s center to the cortex of the jawbone.
Average accuracy of the navigation system was found to be 0.9 ± 0.7 mm, range {0.0 ...3.5} mm. We conclude that these results
show that CAID is an interesting novel application of computer-aided surgery superior to conventional methods in oral surgery.
