Two types of TMJ

Disorders of the temporomandibular joint (TMJ) is a disorder which may be suffered by more than 30 million Americans. Sometimes called "the impostor Great" for his ability to masquerade as other conditions can cause TMJ symptoms as diverse as sleep, face, back pain, toothache, tinnitus and tingling or numbness in the limbs.
The jaw joints are located on either side of the head where the jaw (jaw) meets the skull. Itself is composed of three parts, the articular surface of the skull, described as a pit, the surface of the jaw joint, described as a condyle and disk of cartilage that acts as a cushion between them. TMJ may be caused by a condition in the town itself, in which case it is described as intracapsular or by extraordinary circumstances, in which case it is described as extracapsular.
Intracapsular TMJ
Intracapsular TMJ is the result of some structural changes in one of three components and / or their relationship with each other. They may interfere with the functioning of the jaw and often produce pain, especially pain localized often easy to trace the movement of the jaw, although the true diagnosis of ATM is still very difficult. There are four generally accepted intracapsular TMJ.
Developmental disorders can lead to abnormal development of the joint. They often occur in patients of a relatively young age and tend to be very supportive.
Degenerative diseases such as arthritis, rheumatoid arthritis and tumors (precursors of tumors) attack the joint. Although tumors can be isolated, TMJ arthritis often develops in conjunction with other affected joints. These tend to occur in elderly patients.
Injuries can often lead to displacement of the joint. Although the trauma must not be directly in the jaw, the sudden emergence of such TMJ, it is easy to trace the cause.
Internal disturbances ATM are defined without any evidence of outside influence. Instead, the relationship between the condyle of the pit, and disruption of the disk for no apparent reason.
