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. Horizontal






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






3. Occlusal guard =






4. #10 & #23






5. Crowns tipped lingually - roots tipped laterally






6. Hereditary - Tongue - Intercuspation of teeth - Alignment of previously erupted teeth affects alignment of successive teeth






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






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






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






10. Functional occlusion






11. Lateral mvmt results in contacct of all posterior teeth






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






13. 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






14. Mandible moves to the right or left






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






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






17. Vertical






18. Posterior; no horizontal overlap






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






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






21. Habitual - acquired - convenience - intercuspal & static






22. Excessive occ force with adequate bone support =






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






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






25. Below occlusal plane






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






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






28. Laterally






29. Maximum interlocking of cusp






30. 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






31. Abnormal contacts; occlusal habits - and neuroses






32. Excessive deposition of cementum around the apex - due to excessive occlusal forces






33. Spaces between two teeth






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






35. Mandibular molars more mesial than maxillary molars (most children)






36. 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






37. 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






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






39. Both sides






40. Tooth positioned more lingual






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






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






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






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






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






46. Maxillary anterior teeth stick out labially from tongue thrusting






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






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






49. What is not affected by occ trauma






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