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 extracted






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






3. Relationship of the arches bone to bone;






4. Tooth positioned more lingual






5. When no teeth are contacting on this side






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






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






8. Starts around the mesial of the 1st molar






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






10. After periodontal sugery - mobility will ________






11. II (mal)occlusion






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






13. Vertical overlapping






14. Anterior; no horizontal overlap






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






16. Below occlusal plane






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






18. Overlap of anterior teeth






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






20. 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






21. Horizontal






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






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






24. Later






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






26. 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






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






28. Buck teeth are common and are considered






29. Class III (mal)occlusion of permanent teeth






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






31. #10 & #23






32. Occlusal guard =






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






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






35. What is not affected by occ trauma






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






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






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. Symptom free dentition that 'survives' or 'adapts' to a deviated occl






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






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






42. 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






43. Survival of the dentition despite its deviation from a preconceived hypothetical normal






44. Mandibular molars more distal than maxillary molars






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






46. Maxillary - Mandibular - Facial






47. 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






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






49. Maxillary anterior teeth stick out labially from tongue thrusting






50. Incisal 3rd
