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






2. Maxillary overlap mandibular; whole arch






3. 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






4. Mandibular molars more distal than maxillary molars






5. Spaces between two teeth






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






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






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






9. Buck teeth are common and are considered






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






11. Crowns tipped lingually - roots tipped laterally






12. Excessive occ force with adequate bone support =






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






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






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






16. Functional occlusion






17. Class III (mal)occlusion of permanent teeth






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






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






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






21. Both sides






22. Primary teeth set ___________________ for permanent






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






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






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






26. 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






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






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






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






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






31. Prognathic profile






32. 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






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






34. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious






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






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






37. Middle 3rd






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






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






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






41. Occlusal guard =






42. Vibrational mvmt of a tooth under occ function






43. Below occlusal plane






44. #7 - 26 - 27






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






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






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






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






49. Vertical overlapping






50. 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
