In which TMD condition do you deflect toward the side that is stuck at maximum opening?

Deflection
Deviation
Disc displacement without reduction
Myofascial pain syndrome

The correct answer is: Deflection

Deflection is the correct answer because it refers to the lateral deviation of the jaw in relation to the midline. This occurs when the temporomandibular joint (TMJ) is stuck in the open position, causing the jaw to deviate or deflect towards the side that is stuck. Deviation (option B) refers to the lateral shift of the mandible during movement and is not specific to one side being stuck. Disc displacement without reduction (option C) refers to the TMJ disc being displaced and unable to return to its normal position, leading to limited jaw movement. Myofascial pain syndrome (option D) refers to muscle pain in the jaw, head, or neck region and does not involve any joint displacement.
