The Accuracy of Cone Beam Computed Tomographybased Registration and Multislice Computed Tomography-based Registration for Oral and Maxillofacial Surgery: A Systematic Review

Objectives: Advances in medical imaging technologies have paved the way for facilitating great challenges in the field of oral and maxillofacial surgery. Medical image registration has become an essential step for a variety of procedures. The goal of this review is to systematically try to answer the following question: Is CBCT based registration and MSCT based registration reliable for maxillofacial surgery? Methods: The PubMed databases, the Lilacs databases and the Chochrane library for systematic reviews were searched till 1 June 2016. Results: The search yielded ten articles evaluating MSCT and CBCT registration techniques after application of certain exclusion criteria. Conclusion: Only one study was comparing the accuracy of CBCT and MSCT registration (markers) for image guided surgery, two studies evaluating CBCT landmark registration technique, four studies evaluating CBCT voxel based registration technique one study comparing the accuracy of CBCT surface based registration and voxel based registration and one study comprised two parts: evaluation of CBCT landmark registration and CBCT voxel based registration.
