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. Difference between primary and secondary occ trauma






3. Teeth are misaligned when biting together






4. Tooth positioned more lingual






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






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






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






8. A tooth that occludes with an opposing tooth before full closure is achieved in centric occlusion






9. Lateral mvmt results in contact btwn the max and mand canines






10. 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






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






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






13. Curve of the occlusal plane; from anterior to posterior - increases with age






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






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






16. Habitual - acquired - convenience - intercuspal & static






17. Mandible moves to the right or left






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






19. Maxillary - Mandibular - Facial






20. Relationship of the arches bone to bone;






21. #7 - 26 - 27






22. 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






23. #10 & #23






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






25. Mandibular molars and maxillary molars are even






26. Measurement of horizontal overlap w/ probe






27. Tooth-tooth contacts; tooth-hard objects contacts; tooth-oral tissues contact






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






29. Vertical






30. Anterior; no horizontal overlap






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






32. Retrognathic profile






33. Above occlusal plane






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






35. 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






36. Cervical 3rd






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






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






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






40. After periodontal sugery - mobility will ________






41. Overlap of anterior teeth






42. Primary teeth set ___________________ for permanent






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






44. Tongue thrusting; thumb sucking - pacifiers






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






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






47. Mandibular molars more distal than maxillary molars






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






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






50. Rotated or twisted; rotated mesial or distal
