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. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






2. A tooth that occludes with an opposing tooth before full closure is achieved in centric occlusion






3. Mandibular molars more distal than maxillary molars






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






5. Spaces between two teeth






6. Starts around the mesial of the 1st molar






7. Cervical 3rd






8. Retrognathic profile






9. Overlap of anterior teeth






10. ____ is not a sign of occl trauma






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






12. Horizontal






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






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






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






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






17. Maxillary anterior teeth stick out labially from tongue thrusting






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






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






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






21. Tooth extracted






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






23. #10 & #23






24. Relationship of the teeth in opposite arches; static position






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






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






27. Aquired centric occlusion - habitual occlusion - convienience occlusion - or intercuspal position






28. Mandibular molars and maxillary molars are even






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






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






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






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






33. Maxillary overlap mandibular; whole arch






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






35. Guidance for protrusive occ should be on the






36. Abnormal contacts; occlusal habits - and neuroses






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






38. Both sides






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






40. Can affect the TMJ - muscles of mastication - pulp and integrity of restorations






41. Lateral mvmt results in contacct of all posterior teeth






42. Mesognathic profile






43. Teeth that are in func when the mandible moves in lateral or protrusive excursions or mvmts






44. Functional occlusion






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






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






47. Anterior; no horizontal overlap






48. Horizontal distance of anterior teeth in crossbite






49. Introduced the concept of codestruction






50. What is not affected by occ trauma
