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






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






3. During protrusive occ - ______ is considered undesirable






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






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






6. Introduced the concept of codestruction






7. Patients show evidence or signs and syptoms of occ disease






8. 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






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






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






11. Excessive occ force with adequate bone support =






12. 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






13. Spaces between two teeth






14. 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






15. Starts closer to premolars






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






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






18. Slight buccal inclination of crown - lingual inclination of root






19. II (mal)occlusion






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






21. 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






22. What is not affected by occ trauma






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






24. Maxillary anterior teeth stick out labially from tongue thrusting






25. Maxillary - Mandibular - Facial






26. After periodontal sugery - mobility will ________






27. Retrognathic profile; buccal groove of mand 1st molar-distal to mb cusp of max 1st; distal of mand. canine distal to mesial to max caniine - tendency toward class II






28. Prognathic profile






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






30. Later






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






32. Mandibular molars and maxillary molars are even






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






34. Lateral mvmt results in contact btwn the max and mand canines






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






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






37. Mesially - Labially






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






39. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






40. 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






41. Tongue thrusting; thumb sucking - pacifiers






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






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






44. Tooth extracted






45. Anterior teeth do not occlude - or remain open - while posterior teeth may have a normal occlusion






46. #7 - 26 - 27






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






48. Maximum interlocking of cusp






49. Lateral mvmt results in contacct of all posterior teeth






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