[Radiographic planning and the evaluation of implant treatment].

Radiographic techniques can be used during the pre-, per- and postoperative stages of implant treatment. In the preoperative stage information is needed regarding the quantity and quality of the bone and the relevant anatomical structures of the jaw. Various radiographic techniques are available for this and all have their inherent merits and disadvantages. Occasionally there is a need of a preoperative radiograph i.e. a panoramic or periapical radiograph. In the postoperative stage radiographic techniques are used for the evaluation of bone and implants. In this stage there is a need for detailed and reproducible information regarding the cervical peri-implant bone level, the total height of the jaw and the radiographic density of the peri-implant bone. There is a limited number of radiographic techniques available in this stage.
