This Case Study shows the Cephalometric evaluation of facial changes due to TMJ joint degeneration over a 12 year period. The first tracing was done shortly after the first signs of a possible TMJ condition. Over the next 12 years the client returned for diagnosis, but did not undergo treatment. The measured amount of condylar head degeneration is approximately 11mm. While the tracings included here are not to scale, they are consistent. Generally the degeneration seems to be self limiting in the 10 to 12mm range.
The tracing of the mandibles above shows the amount of joint degeneration over the 12 year period.
