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






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






3. Both sides






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






5. Mandibular molars more distal than maxillary molars






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






7. 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






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






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






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






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






12. Occlusal guard =






13. Maximum interlocking of cusp






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






15. Mb cusp of max 1st molar-buccal groove of mand 1st molar






16. Vibrational mvmt of a tooth under occ function






17. Maximum touching of max and mand






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






19. 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






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






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






22. When no teeth are contacting on this side






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






24. Individual teeth from each arch can be involved in ________________ malocclusion






25. Retrognathic profile






26. Mandible moves to the right or left






27. Starts closer to premolars






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






29. Class III (mal)occlusion of permanent teeth






30. Below occlusal plane






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






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






33. Mobility - migration - pain - premature contact - widening of PDL - parafuntional habits - TMJ problems - all result in _________






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






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






36. Spaces between two teeth






37. Abnormal contacts; occlusal habits - and neuroses






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






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






40. Introduced the concept of codestruction






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






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






43. Relationship of the teeth in which the incisal ridges of the maxillary anterior teeth extend below the incisal edges of the mandibular anterior teeth when the teeth are placed in a centric occlusal relationship






44. Lateral mvmt results in contacct of all posterior teeth






45. Habitual - acquired - convenience - intercuspal & static






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






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






48. Prognathic profile






49. 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






50. Patients show evidence or signs and syptoms of occ disease
