[Application of tomography to dentistry].
The conventional radiograph is the 2D-projection of a 3D-object. Therefore, information about the third dimension is missing. Various x-ray techniques are available to obtain information about the third dimension. Depending on the diagnostic purpose, global information can be obtained by a second radiograph taken with a different angulation (for instance, to localize an impacted tooth). However, sometimes more detailed information is required about the spatial relationship (for instance, when determining the amount of bone mass in implant planning). CT and MRI are the most appropriate techniques when complete volume information is required. In the near future, tomosynthesis and microCT will become available to obtain detailed 3D-information for dental applications.
