The number of implants placed by computer-assisted navigation is rising steadily the last few years. Appl. Professor Dr. Bernhard Pommer, University of Vienna/Austria, examines in this short presentation the advantages of this method for surgeon, patient and science, but also highlights the disadvantages and future options. Dr. Pommer talks about issues like post-surgical pain reduction, operation time, demand for augmentation, precision and deviation. He discusses the results of immediate loading. The soft tissue positioning is difficult because the CT images do not show this. Other issues are the heat development of the pre-drilling and the poor predictability of the bone quality. In the end Dr. Pommer talks about additional use option in the future.
