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 positioned more facial






2. Lateral mvmt results in contacct of all posterior teeth






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






4. Retrognathic profile






5. Maxillary incisors are are lingual to mandibular incisors






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






7. 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






8. Maximum touching of max and mand






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






10. Guidance for protrusive occ should be on the






11. Difference between primary and secondary occ trauma






12. After periodontal sugery - mobility will ________






13. Laterally






14. 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






15. Excessive occ force with adequate bone support =






16. Mesognathic profile






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






18. Buck teeth are common and are considered






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






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






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






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






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






24. Tooth extracted






25. 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






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






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






28. Tongue thrusting; thumb sucking - pacifiers






29. Above occlusal plane






30. Can affect the TMJ - muscles of mastication - pulp and integrity of restorations






31. Abnormal contacts; occlusal habits - and neuroses






32. Spaces between two teeth






33. 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






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






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






36. Habitual - acquired - convenience - intercuspal & static






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






38. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






39. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






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






41. 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






42. Anterior; no horizontal overlap






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






44. Functional occlusion






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






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






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






48. Starts closer to premolars






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






50. 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
