A suitable wooden rod is interposed between the teeth as far back as possible to form a fulcrum, and the operator is carefully closing the jaw as distally as possible. This causes a direct traction force to be generated in the temporo-mandibular articulation on the side of the fulcrum. Traction can be a useful force as it is an accessory movement to the joint and can thus produce mechanical changes that primary movement under the control of the patient's own muscles cannot achieve.
Tips: Most useful where muscle stretch rather than articular work is required and where patient has own teeth. Least useful with dentures. Extra considerations: Pad wooden rod if necessary and vary the thickness to find the optimum tension.
