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






2. Curve spee & wilson - 3-d - not proven






3. Class III (mal)occlusion of permanent teeth






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






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






6. Mand. retruded-one or more max. incisors retruded; max. laterals protruded-max centrals retruded; crowded max anterior teeth; deep overbite






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






8. Crowns tipped lingually - roots tipped laterally






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






10. Buck teeth are common and are considered






11. Maxillary - Mandibular - Facial






12. 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






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






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






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






16. Anterior; no horizontal overlap






17. Maximum touching of max and mand






18. Functional occlusion






19. Mesially - Labially






20. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






21. 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






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






23. Tongue thrusting; thumb sucking - pacifiers






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






25. Incisal 3rd






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






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






28. During protrusive occ - ______ is considered undesirable






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






30. Horizontal distance of anterior teeth in crossbite






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






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






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






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






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






36. 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






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






38. Vibrational mvmt of a tooth under occ function






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






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






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






42. Vertical






43. Overlap of anterior teeth






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






45. Introduced the concept of codestruction






46. Habitual - acquired - convenience - intercuspal & static






47. Starts closer to premolars






48. 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






49. Vertical overlapping






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