Mandible – Orthopantomogram (OPG)Machine
An Orthopantomogram is a panoramic or wide view x-ray of the lower face, which displays all the teeth of the upper and lower jaw on a single film. It demonstrates the number, position and growth of all the teeth including those that have not yet surfaced or erupted.
A panoramic Radiographic device that images the entire dentition, alveolar bone, and other contiguous structures on a single extraoral film.
The principal advantage of panoramic images/OPGs:
- Broad coverage of facial bones and teeth including the TMJ (Temperomandibular joint)
- Low patient radiation dose
- Convenience of examination for the patient
- Ability to be used in patients who are restricted in opening their mouth
- Short time required for producing the image
- Useful visual aid in patient education and case presentation
Importance of Cephalomatric X-Ray
A cephalometric x–ray is a unique tool, which enables the dentist to capture a complete radiographic image of the side of the face. X–rays, in general, offer the dentist a way to view the teeth, jawbone and soft tissues beyond what can be seen with the naked eye.
Importance of TMJ
The Temporomandibular joint (TMJ) or jaw joint is a bi-arthroidal hinge joint that allows the complex movements necessary for life. The TMJ is the joint between condylar head of the mandible and the mandibular fossa of the temporal bone. This system is made up of the TMJ, teeth and soft tissue.
