T.M.D.(Temporo Mandibular Disorders)

MENU Unconscious biting Waribashi Test Biofeedback Self-introduction


Dental caries and pyorrhea alveolaris (or peridontitis) have been long thought as the two most frequent diseases in dentistry. Recently, a third disease has attracted much attention. I am interested in and studying this third disease. Although there are many things to be investigated and there is no definite treatment, let me give you some useful information gathered so far. So what is the third disease? It is a disease called TMD, which affects the face to the neck, especially the jaw joint, and sometimes affects the whole body.

Causes

The problem is that the cause of TMD is unknown. We do not know whether poor occlusion is the immediate cause, or just a trigger. Because its cause has not been identified, various treatments are used now. The treatment greatly depends on the dentist. Thus, what I describe here may be wrong.

In general, the potential causes are divided into occlusion related and non-related ones: occlusion related causes include poor occlusion (dental caries, untreated dental defects, abnormal dentition, and inappropriate dental treatment), bruxism, biting habit, biased biting, development abnormality by insufficient chewing during growth, malformation, trauma, and rheumatism. Occlusion non-related causes include lack of exercise, stress, bad posture, resting the chin on the hand, character, mental disorder, poor shape, situations that require looking downward for a long time such as reading, using a personal computer, and knitting, biting during sporting activities (e.g.. biting when hitting a ball), opening the mouth wide, leg injury, and poor shoes.
Those who are engrossed in the Internet like yourselves may suffer some of the causes.

There are many potential causes of TMD, and almost everyone suffers at least one, and TMD development varies among individuals. This is the main reason why it is difficult to identify the cause. I think poor occlusion may sometimes be the immediate cause, but be one of contributors at another times. I am sorry for not being decisive. In fact, many researchers consider that poor occlusion is not the immediate cause of TMD.


Symptoms

The three main symptoms

  Treating the noise when opening the mouth is most difficult. However, it is better not to become nervous.

Other symptoms 

Although almost everyone has at least one of the following many symptoms, past literature shows that all of them play a part. Some researchers concentrate on the symptoms around the mouth. However, such abundance of the symptoms shows that TMD may be related to body posture and the autonomic nervous system, and affect the whole body. The most frequent complaints for the body sites other than the mouth are headache and shoulder stiffness.
