[Depiction of oral implants on radiographs]

An enormous number of products and types of oral implants exists. In identification of implants previously inserted by other dentists radiography is essential. The radiographic images of 14 fixtures were analyzed and explained based on experimental exposures under standardized circumstances. In particular was the influence of different viewing angles due to rotational position of the fixture described. It is concluded that any of the metallic fixtures studied possesses macrostructures which will lead to a unique radiographic image making it possible to recognize it on radiographs. On the other hand the images will vary widely depending on rotational stage of the fixture why a thorough knowledge of the detailed architecture of the implants is necessary.
