The flashcards below were created by user jcap87 on FreezingBlue Flashcards. What would you like to do?


  1. 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.
  2. 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
  3. 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
  4. 6. In what sequence and how are occlusal reshaping procedures performed when utilizing the monoplane concept of complete denture occlusion?
    after processing, remount casts and if pin is >0.5 then no shaping

    if >0.5, shape mandibular posterior teeth til 0.5 or less and equal posterior contacts

    check with mylar strip
  5. 7. When utilizing the monoplane concept of complete denture occlusion, why is freedom of movement for 2.0 to 3.0 mm in all eccentric excursions of the mandible essential? How is this freedom of movement provided?
  6. 8. What are the advantages of using nonanatomic posterior denture teeth and the monoplane concept of complete denture occlusion?
  7. 9. What are the disadvantages of using nonanatomic posterior denture teeth and the monoplane concept of complete denture occlusion? How can the disadvantages of nonanatomic posterior denture teeth and the monoplane concept of complete denture occlusion be addressed?
  8. 10. When utilizing the monoplane concept of complete denture occlusion, what are the procedures involved in arranging resin maxillary nonanatomic posterior denture teeth with metal cutter bars opposing porcelain mandibular nonanatomic posterior denture teeth? What are the steps involved in restoring the anatomy and polishing the occlusal surfaces of the resin maxillary nonanatomic posterior denture teeth with metal cutter bars? What are the steps involved in restoring the anatomy and polishing the occlusal surfaces of the porcelain mandibular nonanatomic posterior denture teeth?
  9. 11. What equipment and materials are used in arranging maxillary and mandibular nonanatomic posterior denture teeth in a nonbalanced denture occlusion?
  10. 12. In preparation for arranging maxillary and mandibular nonanatomic posterior denture teeth in a nonbalanced denture occlusion, how should the following features on an articulator be set: The horizontal condylar guidances? The lateral condylar guidances? The centric locks? The anterior guide pin? The mounting plates? The horizontal inclination of the anterior guide table? The lateral wings of the anterior guide table?
  11. 13. What four criteria should be used to evaluate the height of a maxillary occlusion rim prior to arranging maxillary and mandibular nonanatomic posterior denture teeth in a nonbalanced denture occlusion?
  12. 14. What two criteria should be used to evaluate a mandibular occlusion rim prior to arranging maxillary and mandibular nonanatomic posterior denture teeth in a nonbalanced denture occlusion?
  13. 15. Why are mandibular nonanatomic posterior denture teeth arranged before maxillary nonanatomic posterior denture teeth?
  14. 16. What three guidelines are used to arrange mandibular nonanatomic first premolars?
  15. 17. What three guidelines are used to arrange mandibular nonanatomic second premolars and molars?
  16. 18. When evaluating an arrangement of mandibular nonanatomic posterior denture teeth: Which denture teeth and which cusps should contact a flat occlusal guide plate? How should the adjacent marginal ridges be positioned? How should the central fossae be positioned?
  17. 19. What tooth sequence should be used for arranging maxillary nonanatomic posterior denture teeth?
  18. 20. What buccolingual relationship should maxillary nonanatomic posterior denture teeth have to mandibular nonanatomic posterior denture teeth?
  19. 21. When is a reverse articulation or cross bite arrangement of nonanatomic posterior denture teeth indicate?
  20. 22. How can the facial ridges of maxillary canines, premolars and molars be used to ensure that one or more of the maxillary nonanatomic posterior denture teeth are not grossly malaligned? When evaluating an arrangement of maxillary nonanatomic posterior denture teeth, which is more important: how the maxillary and mandibular posterior denture teeth occlude or the relationship of the facial ridges of the maxillary posterior denture teeth?
  21. 23. Why must the occlusal surfaces of nonanatomic posterior denture teeth be absolutely flat?
  22. 24. What is a common esthetic problem associated with nonanatomic posterior denture teeth? How can this problem be avoided?
  23. 25. When evaluating an arrangement of maxillary nonanatomic posterior denture teeth: Which denture teeth and which cusps should contact a flat occlusal guide plate? How should the adjacent marginal ridges be positioned? How should the central fossae be positioned? How should the lingual cusps be positioned?
  24. 26. When maximum occlusal contacts between the maxillary and mandibular nonanatomic posterior denture teeth are established, which posterior denture teeth should be rearranged to produce maximum occlusal contacts?
  25. 27. What are the objectives of rearranging mandibular posterior denture teeth to establish maximum occlusal contacts between the maxillary and mandibular nonanatomic posterior denture teeth?
  26. 28. What is the posterior limit of the occlusal surfaces of mandibular posterior denture teeth?
  27. 29. Instead of articulating ribbon, what should be used to determine if there are multiple, uniform occlusal contacts between the maxillary and mandibular nonanatomic posterior denture teeth during posterior denture tooth arrangement?
  28. 30. When considering the nonanatomic posterior denture teeth, the monoplane concept of complete denture occlusion, and the articulator settings, why should there be no occlusal interferences between maxillary and mandibular nonanatomic posterior teeth during eccentric excursions of the mandible?
  29. 31. When using the monoplane concept of complete denture occlusion, ideally how should the maxillary and mandibular anterior denture teeth be arranged? If esthetic demands do not allow the ideal anterior denture tooth arrangement, what guidelines can be used to minimize anterior interferences during functional movements of the mandible? When may anatomic posterior denture teeth arranged in a balanced complete denture occlusion be indicated instead of nonanatomic posterior denture teeth arranged in a nonbalanced complete denture occlusion?
  30. 32. Why should voids between the denture teeth and the baseplate wax be eliminated prior to clinical evaluation of the trial dentures?
  31. 33. Why is it advisable to reevaluate occlusal contacts between the maxillary and mandibular nonanatomic posterior denture teeth after contouring the denture bases?
  32. 34. What evaluation criteria are used to assess the quality of nonanatomic posterior denture teeth arranged in a nonbalanced denture occlusion?
