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. After periodontal sugery - mobility will ________






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






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






4. Difference between primary and secondary occ trauma






5. Mandibular molars and maxillary molars are even






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






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






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






9. When no teeth are contacting on this side






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






11. Starts closer to premolars






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






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






14. Maxillary - Mandibular - Facial






15. Both sides






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






17. Abnormal contacts; occlusal habits - and neuroses






18. Tongue thrusting; thumb sucking - pacifiers






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






20. ____ is not a sign of occl trauma






21. Patient forces teeth together in centric occlusion on one side to get a more functional bite and has a crossbite on the other side(the midline of the maxillary anterior teeth does not line up with the midlineof the mandible






22. Permits healing of the attachment apparatus by holding a tooth in a totally fixed position; allows the PDL to become narrower and the mobility to be reduced






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






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






25. Mandible moves to the right or left






26. Maxillary overlap mandibular; whole arch






27. Excessive occ force with adequate bone support =






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






29. Tooth positioned more facial






30. 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






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






32. Relationship of the arches bone to bone;






33. Tooth positioned more lingual






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






35. Radiographically - the PDL space is wider at the coronal third of the root






36. Horizontal






37. Measurement of horizontal overlap w/ probe






38. Rotated or twisted; rotated mesial or distal






39. Muscles that work the jaw; may become sore due to occ trauma






40. What is not affected by occ trauma






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






42. II (mal)occlusion






43. #7 - 26 - 27






44. Maximum interlocking of cusp






45. Individual teeth from each arch can be involved in ________________ malocclusion






46. Tooth extracted






47. Retrognathic profile






48. Class III (mal)occlusion of permanent teeth






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






50. During protrusive occ - ______ is considered undesirable
