Calibrated segmentation of CBCT and CT images for digitization of dental prostheses

Abstract

State of the art computer aided implant planning procedures typically use a surgical template to transfer the digital 3D planning to the operating room. This surgical template can be generated based on an acrylic copy of the patient’s removable prosthesis—the so-called radiographic guide—which is digitized using a CBCT or CT scanner. Since the same accurate fit between the surgical template and the patient as with the radiographic guide and the patient should be ensured, a procedure to accurately digitize this guide is needed.
