TMJ deformities/deviations

TMJ deformities/deviations

According to the Injury classification system, TMJ deformities/deviations with no other associated conditions, is considered Level 1 Injury, as per the main dysfunction being found at the first Alignment protective layer.

There are three deformities syndromes

Malocclusion syndrome is a misalignment or incorrect relation between the teeth of the two dental arches when they approach each other as the jaws close. One of the causes for the development of this condition is an impaired TMJ alignment associated with increase hypertonicity of certain muscles of mastication shifting the jaw into a inappropriate position as it closes.


Locked TMJ is a condition that ‘’locks’’ the jaw joint in a closed position not allowing the proper opening of the mouth. Its generally caused by a rare dysfunction where the jaw misaligned posterior superior not allowing the jaw to drop and protract forward during normal mouth mechanics. Significant trauma on the chin while the month is slightly open,  tends to drive the jaw into this misalignment pattern.


TMJ Deviated syndrome is a common condition that causes the jaw to deviate right or left in opening of the mouth. There are 2 TMJ misalignment responsible for this disorder; Anterior inferior (AI ) and External (EX) TMJ misalignments.



Assessment Protocol

Clinical assessment to identify the key joint dysfunctions of the jaw and the associated muscles compromised.

Anterior – Posterior (AP) X-ray cervical/Jaw view is essential to check the patterns of TMJ misalignment


Treatment protocol

Specific jaw adjustments followed by a rehabilitation regime to strengthen the entire soft tissue arch support of the TMJ.

Muscles soft tissue techniques

Depending on level of misalignment and chronicity of the deformity a minimum of 6 weeks up to 12 weeks of treatment care may be necessary to resolve this deformity.
