(cuspal interference), a condition of tooth contacts that diverts the mandible from a normal path of closure to centric jaw relation or causes a denture to slide or rotate on its basal seat.
a type of malocclusion occurring in persons who cannot close all their teeth while holding their condyles in the rearmost position. Instead, in closure they first contact one or two pairs of poorly coupled teeth. To gain occlusal contacts of the other teeth, they must move the jaw anteriorly, laterally, or anterolaterally, as the deflectors demand in their guidance.
