What Is TMJ?
TMJ stands for “temporo-mandibular joint.” Your temporo-mandibular joint is the hinged joint which connects your jaw to the temporal bones of your skull. A problem or disfunction of this joint is referred to as TMD or temporo-mandibular dysfunction. While not totally accurate, many times the terms TMJ and TMD are used interchangeably to describe temporo-mandibular joint disfunction.
The top diseases associated with Temporo-Mandibular Dysfunction (TMD) are:
- OMD (Occluso-Muscular Disharmony)
- Physical damage to disc or ligament of the joint
- Avascular Necrosis
- Progressive Condylar Resorption
- Osteochondritis Dissecans
- Lyme Disease
Nearly 80 percent of TMD is caused by OMD. This is good news for most people who suffer with TMD since it can usually be solved with the proper therapies.
This “machine” of ours is comprised of teeth, muscles, bone, joint, ligaments and a brain that controls it all. A change in any one area will affect the others. The easiest part of this machine to change is the teeth. By affecting a change to the teeth, we can affect the other parts of the system and improve the mouth’s function.
The first and most common treatment is splint therapy. Splint therapy is a way to artificially create an ideal bite and create harmony in the system. Many times, teeth get in the way of the joint properly seating; when this happens, muscles have to brace and work harder to stabilize the joint. A splint can correct this issue and allow the muscles to relax and seat the joint into a “fully seated joint position.” Splint therapy helps the dentist figure out what is happening with the system. This treatment is diagnostic but can also be therapeutic. Splints are more than a piece of plastic your dentist sends off to a dental lab to be made. They require extreme precision and skill to tune to create a positive change in a patient’s musculature and joint. Splint therapy can take multiple visits over many months.
Another method of TMD treatment is DTR or disclusion time reduction therapy. A little background information is needed to explain this: Every tooth in the mouth is connected to the bone via a periodontal ligament (PDL). These PDL’s give sensory information to the brain that then send signals to the muscles. If teeth hit at the wrong time, then muscles get information telling them to become hyperactive. In contrast, if the correct teeth hit at the right time, the muscles get signaled to relax. Hyperactive muscles can become painful. You know that burning, sore sensation in your muscles after working out? That is caused by lactic acid. This same process can occur in our chewing muscles.
Georgia Dental Medicine℠ regularly employs the use of all these technologies.
A thorough evaluation of the patient, history, range of motion, imaging (3D), listening to the joints and review of the bite should be done prior to any treatment by our dentist.
