1. What does the monoplane concept of complete denture occlusion advocate? How are occlusal forces centralized anteroposteriorly in the monoplane concept of complete denture occlusion? How are occlusal forces centralized buccolingually in the monoplane concept of complete denture occlusion?
- * advocates the neutralizating of all inclines on the occlusal surfaces of posterior denture teeth, as well as the centralization of occlusal forces when the mandible is in centric relation.
- Anteroposteriorly, occlusal forces are centralized by having the area of greatest occlusal contact in the anteroposterior center of the denture bases.
- second premolar-first molar area.
- Buccolingually, occlusal forces are centralized by positioning the posterior denture teeth over, or slightly lingual, to the centers of the posterior residual ridges.

4. When utilizing the monoplane concept of complete denture occlusion, why should the posterior denture tooth arrangement conform to a flat plane?
prevents cuspal interferences during eccentric movements
-
5. How are the five principle factors in “Hanau’s Law of Articulation” theoretically neutralized in the monoplane concept of complete denture occlusion?
inclination of the incisal guidance, the height of the cusps, the inclination of the occlusal plane and the compensating curve, four of the five principle factors in “Hanau’s Law of Articulation”
inclination of condylar guidance - disregarded if MI=CR b/c in this position, condyle doesnt translate and just makes a terminal hinge closure so inclination isnt a factor to consider

6. In what sequence and how are occlusal reshaping procedures performed when utilizing the monoplane concept of complete denture occlusion?

check with mylar strip
