What would likely occur if the left TMJ capsule is restricted?

If the left TMJ capsule is restricted, the most likely outcome is that there would be a deviation to the right upon opening the mouth. This happens because when one side of the temporomandibular joint (TMJ) is less mobile due to restrictions in the capsule, the jaw will naturally compensate. As the left side is restricted, the right side, which remains unrestricted, allows for more movement. Hence, during opening, the jaw would deviate towards the unrestricted side, which is the right side in this scenario.

In cases where a joint is less able to move due to capsular restrictions, the body often compensates by favoring the more mobile side. As a result, in the case of restricted motion on the left TMJ, the jaw does not open straight but rather shifts towards the right side, reflecting a loss of balance in jaw function.

This movement can lead to a variety of issues over time, such as altered occlusion and further discomfort in the TMJ area. It is important to identify this deviation, as it can guide treatment options to restore proper function and balance between the two TMJs.
