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






2. During a left working movement - the right side is known as the






3. 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






4. Starts closer to premolars






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






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






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






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. Vertical overlapping






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






11. Mandibular molars more distal than maxillary molars






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






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






14. Incisal 3rd






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






16. What is not affected by occ trauma






17. Prognathic profile






18. Associated with performance; all contacts during function of the oral cavity






19. Habitual - acquired - convenience - intercuspal & static






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






21. Lateral mvmt results in contacct of all posterior teeth






22. The side to which the mandible moves(chewing side)






23. Cervical 3rd






24. Maximal intercuspation or contact of the max and mand teeth






25. Above occlusal plane






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






27. Class III (mal)occlusion of permanent teeth






28. Abnormal contacts; occlusal habits - and neuroses






29. #10 & #23






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






31. Anterior or posterior; bilateral or unitlateral - anterior more common






32. Tooth positioned more facial






33. Relationship of the arches bone to bone;






34. Maxillary incisors are are lingual to mandibular incisors






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






36. Mesially - Labially






37. Maximum touching of max and mand






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






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






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






41. Middle 3rd






42. Survival of the dentition despite its deviation from a preconceived hypothetical normal






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






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






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






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






47. Starts closer to the posterior of the 1st molar






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






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






50. Maxillary overlap mandibular; whole arch
