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. Guidance for protrusive occ should be on the






2. Excessive occ force with adequate bone support =






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






4. Maxillary incisors are are lingual to mandibular incisors






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






6. Tongue thrust or thumb sucking can cause






7. Buck teeth are common and are considered






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






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






10. Teeth are misaligned when biting together






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






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






13. Anterior; no horizontal overlap






14. Incisal 3rd






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






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






17. Middle 3rd






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






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






20. Tongue thrusting; thumb sucking - pacifiers






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






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






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






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






25. When no teeth are contacting on this side






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






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






28. ____ is not a sign of occl trauma






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






30. Relationship of the arches bone to bone;






31. Maxillary overlap mandibular; whole arch






32. Maximum interlocking of cusp






33. Maxillary anterior teeth stick out labially from tongue thrusting






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






35. Abnormal contacts; occlusal habits - and neuroses






36. Cervical 3rd






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






38. During protrusive occ - ______ is considered undesirable






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






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






41. What is not affected by occ trauma






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






43. Tooth extracted






44. Occlusal guard =






45. #10 & #23






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






47. 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






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






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






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