Surgical segment navigator

The SSN has been developed as a computer system for bone segment navigation in oral and maxillofacial surgery.

[1] It allows a very precise repositioning of bone fragments, with the advent of preoperative simulation and surgical planning.

[2] The system has been developed since 1997 at the University of Regensburg, Germany, with the support of the Carl Zeiss Company.

Since 2001, at the University of Heidelberg, Germany, the SSN++ has been developed, a markerless-registration navigation system, based on a native (=markerless) CT or MRI.

In this case, the patient registration is obtained on the operating table, using a surface scanner.
