This Concept Map, created with IHMC CmapTools, has information related to: MPO ver 8, MUTUALLY PROTECTED OCCLUSION has the ff. features 2. Stable posterior tooth contacts with verically directed resultant forces, working movements either through CANINE GUIDANCE, CANINE GUIDANCE is an occlusal scheme, occlusion is Angle Class I rationale effectiveness of the force exerted by the muscles of mastification is notable less when the loading contact occurs farther anteriorly, logical scheme to protect the teeth, interfered by tooth contacts either natural, posterior teeth protects anterior teeth, it has 2 planes, difficult to prep such that mesiolingual plane corresponds to anterior, MUTUALLY PROTECTED OCCLUSION has the ff. features 1. Uniform contact of all teeth around the arch when the mandibular condylar processes are in their most superior position (centric occlusion), natural teeth because have the benefit of being attached to bone, have the benefit of being attached to bone therefore anteriors should not touch, WORKING GUIDANCE seen on the working side, MUTUALLY PROTECTED OCCLUSION has the ff. features 5. Anterior tooth contacts harmonizing with functional jaw movements, posterior teeth have multiple number of roots, when achieved can be assumed that healthy supporting tissues, interfered by tooth contacts called Occlusal Interferences, 3. Centric relation coincident with maximum intercuspation (intercuspal position) in some cases centric relation does not coincide with maximum intercuspation, functional cusps to long axis of opposing tooth, the most widely accepted arrangement of teeth because it is well tolerated by patients, anteriors should not touch when posterior teeth in maximum intercuspation (e.g. chewing)
