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. Widening of the PDL in areas under pressure results due to






3. Guidance for protrusive occ should be on the






4. Tooth positioned more facial






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






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






7. Maxillary overlap mandibular; whole arch






8. Vibrational mvmt of a tooth under occ function






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






10. Tooth positioned more lingual






11. Spaces between two teeth






12. Teeth are misaligned when biting together






13. Measurement of horizontal overlap w/ probe






14. Maximum touching of max and mand






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






16. Cervical 3rd






17. Abnormal contacts; occlusal habits - and neuroses






18. Excessive occ force with adequate bone support =






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






20. The patient is constantly tightening the lower lip against the lower anterior teeth causing the the mandibular teeth to be pushed back into the mouth by this overdeveloped lower lip






21. Difference between primary and secondary occ trauma






22. Horizontal






23. Maximum interlocking of cusp






24. Mandibular molars and maxillary molars are even






25. Above occlusal plane






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






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






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






29. Malocclusion cause excessive incisal or occlusal wear(attrition); teeth continue to erupt in order to occlude with teeth in the opposite arch & roots become exposed






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






31. Primary teeth set ___________________ for permanent






32. Mandible moves to the right or left






33. During protrusive occ - ______ is considered undesirable






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






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






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






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






38. Habitual - acquired - convenience - intercuspal & static






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






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






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






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






43. Both sides






44. Laterally






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






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






47. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






48. Starts closer to premolars






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






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