Maximal intercuspal position is:

• A. The complete intercuspation of the opposing teeth independent of condylar position
• B. An untranslated hinge position
• C. The dynamic relationship of the mandibular anterior teeth
• D. The position of the tooth when lingual forces are balanced with labial forces

Answer: (A)

Maximal intercuspal position is the complete intercuspation of the opposing teeth independent of condylar position. It’s the point where the teeth fit together with the greatest number of contacts, driven by tooth shape and occlusal surfaces rather than a fixed jaw position. The condyles can be in different positions while this maximum tooth contact is achieved, which is why the definition emphasizes tooth contacts over joint position. This differs from a pure hinge position (jaw closure without tooth contact), from the dynamic anterior guidance created by the incisors, and from a balanced force scenario, which relate to movement and force distribution rather than the endpoint of maximal tooth contact. Thus, the statement describing complete intercuspation of the opposing teeth independent of condylar position best captures maximal intercuspal position.
