Q. Illustrate Bite-wing radiographs?
The short and long-term evaluation of crestal bone loss around implants is best evaluated with intraoral radiographs. Threaded implants make quantification of marginal bone loss easier to read. Most threaded implants have a smooth crestal region that measures 0.8 to 2 mm, depending on the manufacturer, before the threads begin. Once the threads begin, there is a consistent pitch (distance between the threads). As a result, the amount of crestal bone loss can be determined when compared to the original implant insertion and initial radiograph of the prosthesis.
