OPG — orthopantomography, an X-ray technique

Bone quality is assessed using low-dose digital X-rays, the orthopantomogram.

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.

Frequently asked questions

In most cases yes. The orthopantomogram (OPG), a two-dimensional panoramic image of the jaw, has proved its worth in implant diagnostics and as a rule provides enough information about the amount of bone available. Where bone volume is lacking or bone quality is poor, additional diagnostic steps may be added.
It is important that the course of the nerve in the lower jaw (Nervus mandibularis) can be clearly seen and is shown. Only then is the panoramic image suitable as a basis for planning the implant position. On screen the panoramic images can be analysed at leisure.
