Final answer:
When establishing balanced occlusion, the lingual cusps of maxillary posterior teeth should contact the buccal cusps of the mandibular posterior teeth on the non-working side. This promotes stability during mastication.
Step-by-step explanation:
When establishing balanced occlusion, the lingual cusps of maxillary posterior teeth on the non-working side should contact the buccal cusps of the mandibular posterior teeth on the working side. This helps distribute forces evenly and promotes stability during mastication.
contacts are made in such a way as to minimize tipping, rotation, or displacement of the dentures during function. The goal is to establish even contact on both sides of the mouth to maintain stability of the dentures during mastication and to avoid interference that could unsettle the dentures.
