Computerized tomography-based imaging and surgical guidance in oral implantology.

Computerized tomography (CT)-based imaging and surgical guidance carry both radiographic information such as height, density, and width of bone and clinical information such as axis of orientation for a successful prosthodontic result, thus determining the trajectory, depth, and distribution of the implants. The objective of this report is to review the associated literature and recent developments in CT-image-based information and surgical guidance systems. This report attempts to provide an argument for the development of evidence-based research on the utility of such systems and their effect on outcome in oral implantology.
