Spiral Dental CT: Use in Evaluating Dental Implantation

Preoperative evaluation for the dental implanting normally starts with a thorough physical examination of the oral cavity and dental arches to determine the potential sites for the implant placement. Spiral dental CT plays a very important role in preoperative evaluation and postoperative follow up. It provides both 2 and 3-dimensional images, showing soft tissues and alveolar bone in each area, and it can be used to select the sites of implantation and to evaluate the angulations, the density and the contour of the alveolar bone, as well as the width and depth of the edentulous ridge.
