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. Patients show evidence or signs and syptoms of occ disease






2. Guidance for protrusive occ should be on the






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






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






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






6. Difference between primary and secondary occ trauma






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






8. Starts closer to premolars






9. Mandibular molars and maxillary molars are even






10. Anterior; no horizontal overlap






11. Prognathic profile






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






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






14. Maxillary overlap mandibular; whole arch






15. Mandibular molars more distal than maxillary molars






16. 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






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






18. Mesognathic profile






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






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






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






22. Excessive occ force with adequate bone support =






23. Relationship of the arches bone to bone;






24. Cusps of maxillary teeth directly over cusps of mandibular teeth






25. Habitual - acquired - convenience - intercuspal & static






26. Mandible moves to the right or left






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






28. Spaces between two teeth






29. Laterally






30. Rotated or twisted; rotated mesial or distal






31. 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






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






33. Tooth positioned more lingual






34. Tongue thrust or thumb sucking can cause






35. Mb cusp of max 1st molar-buccal groove of mand 1st molar






36. Later






37. Tooth extracted






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






39. 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






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






41. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






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






43. Horizontal distance of anterior teeth in crossbite






44. Horizontal






45. Vertical overlapping






46. Lateral mvmt results in contacct of all posterior teeth






47. Functional occlusion






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






49. Middle 3rd






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