This document discusses different occlusal schemes for functional occlusal wax ups. It describes the cusp-marginal ridge scheme developed by E.V. Panye and H.C. Lundeen which mimics the occlusal anatomy of most natural dentitions, with buccal cusps contacting marginal ridges and lingual cusps not contacting. It also describes the cusp-fossa scheme developed by P.K. Thomas where maxillary cusp tips contact mandibular fossae. The document provides details on placing cusps on maxillary and mandibular teeth for these different schemes and techniques for waxing up teeth according to the cusp-marginal ridge scheme. It emphasizes providing freedom
