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






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






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






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






5. Primary teeth set ___________________ for permanent






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






7. Below occlusal plane






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






9. Measurement of horizontal overlap w/ probe






10. The relationship of the teeth in the mandibular arch to those in the maxillary arch as they are brought together






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






12. Overlap of anterior teeth






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






14. The way you normally bite your teeth together when not chewing






15. Starts closer to premolars






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






17. Mandibular molars more distal than maxillary molars






18. #10 & #23






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






20. Difference between primary and secondary occ trauma






21. Crowns tipped lingually - roots tipped laterally






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






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






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






25. 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






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






27. 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






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






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






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






31. Maxillary incisors are are lingual to mandibular incisors






32. During protrusive occ - ______ is considered undesirable






33. Mandible moves to the right or left






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






35. Maxillary overlap mandibular; whole arch






36. Starts around the mesial of the 1st molar






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






38. Horizontal






39. Laterally






40. Mandibular molars and maxillary molars are even






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






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






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






44. 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






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






46. Rotated or twisted; rotated mesial or distal






47. Vibrational mvmt of a tooth under occ function






48. Introduced the concept of codestruction






49. Tooth positioned more facial






50. 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
