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.

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. Need tooth to tooth contact on both working and non working sides to func effectively






2. Habitual - acquired - convenience - intercuspal & static

4. Excessive occ force with adequate bone support =






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






6. Above occlusal plane






7. Maxillary - Mandibular - Facial






8. Retrognathic profile -buccal groove of mand. 1st molar-distal to mb cusp of 1st max.molar -distal of mand canine distal to mesial of max canine - tendency towards class II






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






10. Crowns tipped lingually - roots tipped laterally






11. Functional occlusion






12. Mandibular molars and maxillary molars are even






13. 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






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






15. #10 & #23






16. Rotated or twisted; rotated mesial or distal






17. Lateral mvmt results in contacct of all posterior teeth






18. Tooth positioned more facial






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






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






21. Vertical overlapping






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






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






24. Malposition - crowded anterior teeth - protruded or retruded max incisors - anterior/posterior crossbite - mesial drift






25. ____ is not a sign of occl trauma






26. #7 - 26 - 27






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






28. Cervical 3rd






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






30. Prognathic profile; buccal groove of mand. 1st molar-mesial to mb cusp of max. 1st molar; distal of mand. canine mesial to mesial of max canine; tendency toward class III






31. Vertical






32. Abnormal contacts; occlusal habits - and neuroses






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






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






35. Middle 3rd






36. 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






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






38. Tongue thrust or thumb sucking can cause






39. Tooth extracted






40. Introduced the concept of codestruction






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






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






43. Teeth are misaligned when biting together






44. If the mandible moves to the left - the mvmt is known as a left working movement






45. Starts around the mesial of the 1st molar






46. Tooth positioned more lingual






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






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






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






50. Mandibular molars more distal than maxillary molars
