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. Lateral mvmt results in contacct of all posterior teeth






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






3. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






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






5. Cervical 3rd






6. Functional occlusion






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






8. Tooth positioned more lingual






9. Anterior teeth do not occlude - or remain open - while posterior teeth may have a normal occlusion






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






11. Patients show evidence or signs and syptoms of occ disease






12. Middle 3rd






13. Maximum touching of max and mand






14. Both sides






15. Maxillary - Mandibular - Facial






16. Anterior crossbite; max/mand incisors-edge to edge occlusion; crowded mand. incisors






17. Below occlusal plane






18. Hereditary - Tongue - Intercuspation of teeth - Alignment of previously erupted teeth affects alignment of successive teeth






19. Growth hormone imbalance that causes the mandible to grow faster than the maxilla(all teeth are in crossbite)






20. Incisal 3rd






21. Congenitally missing teeth - Impacted teeth & size and shape of muscle and bone






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






23. Relationship of the arches bone to bone;






24. Mesially - Labially






25. Maxillary overlap mandibular; whole arch






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






27. 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






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






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






30. Vertical overlapping






31. Posterior; no horizontal overlap






32. Later






33. Reshaping of the occ or incisal surfaces of teeth to create contacts btwn upper and lower dentition






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






35. Mb cusp of max 1st molar-buccal groove of mand 1st molar






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. Usually indicative of moderate to sever perio and secondary occ trauma






38. Above occlusal plane






39. Laterally






40. Max canine occludes with mand. canine and mand. 1st premolar.






41. ____ is not a sign of occl trauma






42. Occlusal guard =






43. Maxillary anterior teeth stick out labially from tongue thrusting






44. Maximum interlocking of cusp






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






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






47. Tooth positioned more facial






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






49. Habitual - acquired - convenience - intercuspal & static






50. Curved alignment of the occlusal plane when looking from a posterior view(right to left)
