摘要
Dental implants have become an accepted form of permanent tooth replacement. Nearly all implants currently being placed are of the osseointegrated type. These typically consist of three parts: a fixture, an abutment, and a screw or threaded rod. The fixture, usually composed of titanium, can be placed in either a surgically created site in the alveolar ridge or a fresh extraction socket. Diagnostic imaging can play an important role in evaluating patients with such implants. Useful imaging studies include plain panoramic radiography, computed tomography, and computer-reformatted cross-sectional, panoramic, and three-dimensional imaging. Advanced imaging studies can be used to determine the suitability of implant placement, appropriate sites for implant placement, the size of the implant that can be placed, and the need for preimplantation ridge surgery. Postoperatively, advanced imaging studies can show failure of an endosseous implant to osseointegrate, improper placement of an implant, and violation of important structures.
