Tmj Treatment Research

Welcome to the stanford health library. Thank you for coming here tonight. My name is Michele Jehenson and I work at the orofacial pain at the Stanford Pain Center in Redwood City. So today’s topic is TMJ disorders. TMD, I’m going to speak about the nature of the disorder.

What a tmj disorder really is. I’m going to also talk about who is at risk for TMD. And finally, I will touch on the common treatments that are recognized as evidencebased treatment for TMJ disorders. So, I guess it’s customary to.

Talk about disclosures as to if i’m affiliated with any kind of pharmaceutical company or anything like that. I have no disclosures to be done. So, I wanted to first show you the anatomy of a TMJ. It’s a joint that is very unique in the body. It’s one of a kind.

There is a one disc, and you can picture it as a donut. So, it’s a circular, biconcave, just a donut, just doesn’t have the actual hole in the middle. So it’s kind of like a donut shape, and it separates the jawbone, which you see as the rounded bone in the picture, from the skull.

And particularly, the fossa, the articular fossa, and the eminence that you see to the right of the fossa. So the disc is flexible. It’s fiber cartilage, and it offers a perfect interface between the skull and the jaw. It allows for smoother motion.

The joint is also particular in a sense that not only it allows rotation of the joint, but it allows for forward motion of the jaw. So, if you put your hand like slightly over your, in front of your ear and you open your jaw wide and slow, you can see that initially, it just starts rotating and.

Then you can feel it actually advance forward. And for some people, you can actually feel it coming out slightly, because even though the jaw is seemingly fixed, the suture that is in the front, it allows for certain flexibility in and out of the joint itself. So, what is a TMJ disorder?.

So, a tmj disorder is defined by pain, either at rest or upon function. It is defined by something that is a painful noise. It can also be just a dysfunction, like a limited range of motion, or a jaw deviation such as this, like when you open you go to one side or.

Hubbard on TMJ Clenching Grinding Teeth Hubbard and Leath Dental Rochester Hills MI

About a third of our patients we find have either a clenching or grinding habit. Maybe it’s this world we live in, kind of stressful and intense but it’s really amazing what we can do. Sometimes it’s just using a little physical therapy, a lot of times that’s our initial approach is to get a patient stretching a little bit, try to get them sleeping a little better.

A lot of the newer research is showing that it happens during the lighter forms of sleep so a lot of times the patients that are grinding or clenching their teeth aren’t sleeping real well at night. If we can augment their sleeping patterns a little bit, that seems to help. Lastly, we can do something like an occlusal guard. An occlusal guard is good for temporomandibular disorder which is mostly a muscular disorder. There are other things that can go wrong with a TMJ.

If we don’t think that it’s a muscular disorder, maybe an arthritic disorder or something like that, we’ll often refer that to a specialist for further evaluation and treatment. Probably by far the majority of the cases a simple occlusal guard or splint will alleviate a lot of the symptoms. We also find too that just looking at it through the years it’s kind of an episodic thing. It will bother them for a couple of months then it won’t bother them for a couple months.
