What is the significance of a "reciprocal click"?

What will be an ideal response?


ANS: A person with an anteriorly displaced disc will have an audible click on opening and a second
when the mouth closes. On mouth opening, the condyle slips forward and under the disc to obtain
normal relationship with the disc. When the condyle slips under the disc, an audible click is often
present. The reverse relationship occurs upon closure of the mouth. When the click occurs early in
opening and late in closing, the displacement is relatively limited. The later the click occurs in the
opening phase, the more severe the disc dislocation.
