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. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious






2. The relationship of the teeth in the mandibular arch to those in the maxillary arch as they are brought together






3. Maximum touching of max and mand






4. Mesognathic profile






5. Tooth extracted






6. Starts closer to the posterior of the 1st molar






7. Mobility - migration - pain - premature contact - widening of PDL - parafuntional habits - TMJ problems - all result in _________






8. Habitual - acquired - convenience - intercuspal & static






9. Excessive occ force with adequate bone support =






10. Retrognathic profile






11. Primary teeth set ___________________ for permanent






12. High restoration - parafunctional habits - malpositioned tooth - periapical abcess - physical 'blow' - removable partial - ortho mvmt






13. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






14. Functional occlusion






15. Tooth positioned more facial






16. Mandibular molars more distal than maxillary molars






17. The side to which the mandible moves(chewing side)






18. Later






19. 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






20. Vibrational mvmt of a tooth under occ function






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






22. Mesially - Labially






23. Laterally






24. Posterior; no horizontal overlap






25. Excessive deposition of cementum around the apex - due to excessive occlusal forces






26. Maximum interlocking of cusp






27. The permanent molars erupt posterior to the primary teeth and push them all mesially






28. Class III (mal)occlusion of permanent teeth






29. Both sides






30. Associated with performance; all contacts during function of the oral cavity






31. Lateral mvmt results in contacct of all posterior teeth






32. Symptom free dentition that 'survives' or 'adapts' to a deviated occl






33. Horizontal






34. Curve of the occlusal plane; from anterior to posterior - increases with age






35. Lateral mvmt results in contact btwn the max and mand canines






36. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






37. Anterior; no horizontal overlap






38. Maximal intercuspation or contact of the max and mand teeth






39. Normal contacts between max. and mand. teeth; momentary contacts






40. Muscles that work the jaw; may become sore due to occ trauma






41. #10 & #23






42. Prognathic profile






43. During a left working movement - the right side is known as the






44. Vertical overlapping






45. Above occlusal plane






46. Curve spee & wilson - 3-d - not proven






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






48. Mvmt of the mandible in a direction anterior to centric occ






49. Individual teeth from each arch can be involved in ________________ malocclusion






50. Injury to the attachment apparatus (bone - PDL - and cementum) as a consequence of normal or excessive occ forces
