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






2. #7 - 26 - 27






3. Retrognathic profile






4. Tooth positioned more lingual






5. Vertical






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






7. Relationship of the arches bone to bone;






8. Anterior or posterior; bilateral or unitlateral - anterior more common






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






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






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






12. Rotated or twisted; rotated mesial or distal






13. Guidance for protrusive occ should be on the






14. 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






15. Maxillary incisors are are lingual to mandibular incisors






16. Spaces between two teeth






17. Abnormal contacts; occlusal habits - and neuroses






18. Primary teeth set ___________________ for permanent






19. Incisal 3rd






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






21. Class III (mal)occlusion of permanent teeth






22. Mesognathic profile






23. Excessive deposition of cementum around the apex - due to excessive occlusal forces






24. Tongue thrusting; thumb sucking - pacifiers






25. Later






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






27. Occlusal guard =






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






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






30. Curved alignment of the occlusal plane when looking from a lateral view(distal to mesial)






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






32. Horizontal






33. Teeth are misaligned when biting together






34. Vertical overlapping






35. Tooth positioned more facial






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






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






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






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






40. 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






41. Above occlusal plane






42. Tooth extracted






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






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






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






46. Injury to the attachment apparatus (bone - PDL - and cementum) as a consequence of normal or excessive occ forces






47. Difference between primary and secondary occ trauma






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






49. Maxillary overlap mandibular; whole arch






50. Lateral mvmt results in contacct of all posterior teeth
