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






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






3. A continuation of the spee of to extend through the condyle






4. When no teeth are contacting on this side






5. Mandibular molars more distal than maxillary molars






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






7. Functional occlusion






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






9. Above occlusal plane






10. Tongue thrusting; thumb sucking - pacifiers






11. Measurement of horizontal overlap w/ probe






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






13. Tongue thrust or thumb sucking can cause






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






15. Maximum touching of max and mand






16. 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






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






18. Relationship of the teeth in opposite arches; static position






19. Primary teeth set ___________________ for permanent






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






21. Laterally






22. What is not affected by occ trauma






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






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






25. Maxillary - Mandibular - Facial






26. Occlusal guard =






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






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






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






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






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






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






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






34. Teeth are misaligned when biting together






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






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






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






38. 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






39. 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






40. Lateral mvmt results in contacct of all posterior teeth






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






42. Maxillary incisors are are lingual to mandibular incisors






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






44. Posterior; no horizontal overlap






45. Prognathic profile






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






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






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






49. Starts closer to premolars






50. 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
