The overall accuracy of a novel surgical computer‐aided navigation system for placement of endosseous implants was evaluated. Five dry cadaver mandibles were scanned using high resolution computed tomography (HRCT). The position of four interforaminal dental implants was planned on the computer screen and transferred to the cadaver mandibles using VISIT, a surgical navigation software developed at the Vienna General Hospital. The specimens were HRCT‐scanned again to compare the position of the implants with the preoperative plan on reformatted slices after matching of the pre‐ and postoperative data sets using the mutual information technique. The overall accuracy was 0.96±0.72 mm (range 0.0–3.5 mm). No perforation of the mandibular cortex or damage to the mandibular canal occurred. We conclude that computer‐aided implant surgery can reach a level of accuracy where further clinical developments are feasible.
