B. Importance of modiolus: The modiolus or tendinous node is an anatomic landmark near the corner of the mouth that is formed by the intersection of several muscles of the cheeks and lips. These include the orbicularis oris, buccinator, caninus, triangularis, and zygomaticus muscles. None of these muscles have more than one bony attachment, so they depend on the modiolus for isometric contractions. The denture must be designed as to permit the modiolus to function freely.
C. Techniques: Neutral zone- theory that states the belief that muscles should functionally mold not only to the border but to the entire polished surface.
