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. During selective grinding - occlusion should be adjusted In what four relationships






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






3. Abnormal contacts; occlusal habits - and neuroses






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






5. Mandibular molars and maxillary molars are even






6. Later






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






8. Crowns tipped lingually - roots tipped laterally






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






10. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






11. Maxillary overlap mandibular; whole arch






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






13. Introduced the concept of codestruction






14. Cervical 3rd






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






16. Maximum interlocking of cusp






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






18. Need tooth to tooth contact on both working and non working sides to func effectively






19. Relationship of the teeth in which the incisal ridges of the maxillary anterior teeth extend below the incisal edges of the mandibular anterior teeth when the teeth are placed in a centric occlusal relationship






20. During protrusive occ - ______ is considered undesirable






21. Mesially - Labially






22. #10 & #23






23. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






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






25. Retrognathic profile






26. Habitual - acquired - convenience - intercuspal & static






27. Position of the mandible relative to the maxilla during swallowing and other times when the jaw muscles contract






28. Mandible moves to the right or left






29. The tooth has insufficient bone support and normal chewing and swallowing forces are excessive - causing injury to the attachment appartatus






30. Most common cause is when the maxilla does not grow in proportion to the mandible






31. Below occlusal plane






32. When the jaws are closed - the buccal cusps of the mandibular posterior teeth are interlocked between the buccal & lingual cusps of the maxillary teeth






33. Vertical






34. Cusps of maxillary teeth directly over cusps of mandibular teeth






35. Survival of the dentition despite its deviation from a preconceived hypothetical normal






36. #7 - 26 - 27






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






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






39. Vibrational mvmt of a tooth under occ function






40. Difference between primary and secondary occ trauma






41. Maxillary anterior teeth stick out labially from tongue thrusting






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






43. Tooth positioned more lingual






44. Transverse occlusal curvature; posterior teeth; medio-lateral postion (r-l)






45. The way you normally bite your teeth together when not chewing






46. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






47. Posterior; no horizontal overlap






48. 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






49. A continuation of the spee of to extend through the condyle






50. Starts closer to premolars
