Lateral interocclusal records are made in the mouth for the purpose of capturing the position of the condyles in their respective fossae. These records are then used to set the condylar guides to approximate the anatomical limits of the temporomandibular joints (TMJs). This allows the maximum benefit from using an articulator, facilitating the fabrication of accurate restorations with minimal time required for intraoral adjustment when the restoration is cemented.

Because the configuration of the TMJs has a strong determining influence on the movements of the mandible, the occlusal morphology of any restoration placed in the mouth must be in harmony with the movements of the mandible to prevent the initiation of occlusal disharmony and trauma. Cusp placement, cusp height, groove direction, and groove depth are all features ultimately affected by TMJ configuration. ⁹
