Abstract
Background
All intraoperative navigation systems need a referencing procedure prior to utilization, usually requiring an additional CT or CBCT scan. As new techniques in the field of CAD/CAM have evolved, it seemed favorable to develop a new referencing method not relying on additional CT or CBCT scans.
Methods
A digital maxillary dental scan was used to create a referencing splint by CAD/CAM containing four reference points. By matching scanned dental model and initial trauma‐CT, the splints position and thus the reference points were digitally simulated. These splints STL data was imported into the navigation system. This data was also 3D printed and the resulting piece was placed on the anatomical models' teeth. The methods accuracy was then assessed in vitro.
Conclusion
Our method for referencing of intraoperative navigation can be feasible to avoid an additional CT or CBCT prior to navigation.
