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






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






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






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






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






6. What is not affected by occ trauma






7. Mand. facial or lingual to max. - unitlateral or bilateral; incorrect horizontal overlap






8. Maxillary - Mandibular - Facial






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






10. Relationship of the arches bone to bone;






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






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






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






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






15. Vertical






16. Laterally






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






18. ____ is not a sign of occl trauma






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






20. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






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






22. Tooth positioned more lingual






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






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






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






26. Starts closer to premolars






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

38. Spaces between two teeth






39. Guidance for protrusive occ should be on the






40. Maxillary anterior teeth stick out labially from tongue thrusting






41. Later






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






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






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






45. Below occlusal plane






46. Horizontal






47. Maxillary incisors are are lingual to mandibular incisors






48. Occlusal guard =






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






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