This week I am showing an example of an ideal pantomograph along with 6 criteria that are used when determining the quality of a pantomograph. The next couple weeks will be showing examples of when those 6 criteria are not met and how to correct them.
1. Patient has anterior teeth in notches on bite block.
2. Patient has midline (anterior and posterior of head) aligned with sagittal midline indicator light creating symmetry between the left and right side of the patient.
3. Frankfort horizontal plane is positioned on the correct anatomical landmarks creating a slight concave occlusal plane.
4. Patient standing or sitting tall to prevent overlap of the cervical vertebrae over the ramus of the mandible.
5. Patient has tongue to roof of the mouth and lips around bite block or closed together gently.
6. No visible metal present other than restorative materials.
This effects several areas of the patient including the lateral aspect of the ramus and nasal cavity regions. If there is no visible metal present obscuring the image (blue circles), this criteria has been met.
The ideal pantomograph without any animations.
If you have any questions or comments, please let me know. Thanks and enjoy!
