Dentistry Occlusion

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Incisal 3rd






2. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation

10. Tooth-tooth contacts; tooth-hard objects contacts; tooth-oral tissues contact






11. Functional occlusion






12. Selective grinding should always be completed after ______ has been controlled






13. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






14. Slight buccal inclination of crown - lingual inclination of root






15. Mand. retruded-max. incisors protruded; deep overbite; excessive overjet - abnormal muscle function - short mandible - short upper lip






16. Prognathic profile






17. Most retruded position of the mandible in relation to the maxilla From which lateral mvmts of the jaw can be made






18. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






19. Class III (mal)occlusion of permanent teeth






20. Mand. retruded-one or more max. incisors retruded; max. laterals protruded-max centrals retruded; crowded max anterior teeth; deep overbite

28. Retrognathic profile






29. After periodontal sugery - mobility will ________






30. Difference between primary and secondary occ trauma






31. Patient forces teeth together in centric occlusion on one side to get a more functional bite and has a crossbite on the other side(the midline of the maxillary anterior teeth does not line up with the midlineof the mandible






32. Because the permanent premolars are narrower than the primary molars that they replace - this is what happens when the premolars erupt






33. Contact between maxillary incisors does not line up with contact of mandibular incisors






34. Maxillary anterior teeth stick out labially from tongue thrusting
