OPG — orthopantomography, an X-ray technique

Bone quality is assessed using low-dose digital X-rays. The images of the orthopantomogram (OPG), a two-dimensional X-ray technique, are available as digital data. The OPG has proved itself in implant diagnostics and in most cases is enough as a basis for planning the implant position. What matters is that the path of the mandibular nerve in the lower jaw is clearly visible and imaged. As a rule the OPG supplies enough information to determine the bone available. Panoramic images can be analysed on the computer screen. Digital radiography does without classic film: the data and images are passed straight to a computer. This digital form of the image is considerably easier to read and more accurate than classic X-rays. The cost of an orthopantomogram is covered by statutory health insurance.

In critical situations – insufficient bone volume, poor bone quality – and for complicated procedures, further detailed diagnostic steps can follow.
