Which of the following is false regarding lingualized occlusion and tooth selection?

In the context of denture fabrication and occlusion concepts, it is crucial to understand the principles outlined by Pound and Murrell regarding tooth selection. The assertion that the maxillary teeth should be set at a 33° angle while the mandibular teeth should be at 20° is indeed considered false in relation to lingualized occlusion.

Lingualized occlusion specifically emphasizes achieving a harmonious relationship between the upper and lower dentition, where the maxillary posterior teeth can be more cusped (in this case, a 33° angle) for better occlusal support. However, the mandibular posterior teeth are typically suggested to be flatter, usually around a 0° angle for optimal compatibility with the occlusal plane established by the maxillary teeth. This enhances stability during function while providing a more efficient occlusal contact pattern.

The other statements accurately reflect the standards regarding tooth positioning in lingualized occlusion. Evened-out marginal ridges in mandibular posterior teeth help in achieving a flat occlusal plane which is fundamental in lingualized occlusion, enhancing occlusal stability and aiding in even distribution of occlusal forces. The compensating curve, which begins with the first molars, is integral in maintaining
