Abstract

For existing implant prostheses that have been in the oral cavity for a long time, there are cases in which remaking is necessary for reasons such as abutment and prosthesis damage, occlusal plane, and crown contour. In order to fabricate implant prostheses, components suitable for the implant system, such as impression coping and laboratory analog, are required. Such components may not be available due to company closures or difficult imports. In this case, a laboratory analog that could not be obtained because it was not imported was directly fabricated using reverse engineering, computer-aided design and computer-aided manufacturing technology. As the history of dental implants becomes longer, utilization of this method will be great, and its clinical significance will be important.
