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. Tooth extracted






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






3. Overlap of anterior teeth






4. Vertical overlapping






5. Maxillary - Mandibular - Facial






6. Functional occlusion






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






8. Maxillary-between canines and laterals - mandibular-between canines and 1st molars






9. Primary teeth set ___________________ for permanent






10. Occlusal guard =






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






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






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






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






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






16. Crowns tipped lingually - roots tipped laterally






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






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






19. 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






20. Horizontal






21. Congenitally missing teeth - Impacted teeth & size and shape of muscle and bone






22. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






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






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






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






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






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






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






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






30. Vertical






31. Maximum touching of max and mand






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






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






34. 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






35. Habitual - acquired - convenience - intercuspal & static






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






37. Relationship of the arches bone to bone;






38. Class III (mal)occlusion of permanent teeth






39. Tooth positioned more facial






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






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






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






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






44. Mand. retruded-max. incisors protruded; deep overbite; excessive overjet - abnormal muscle function - short mandible - short upper lip






45. 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






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






47. Both sides






48. Excessive occ force with adequate bone support =






49. Abnormal contacts; occlusal habits - and neuroses






50. The way you normally bite your teeth together when not chewing
