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. Primary teeth set ___________________ for permanent






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






3. If the mandible moves to the left - the mvmt is known as a left working movement






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






5. Cervical 3rd






6. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation






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






8. Starts closer to premolars






9. Occlusal guard =






10. II (mal)occlusion






11. What is not affected by occ trauma






12. Maxillary incisors are are lingual to mandibular incisors






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






14. Tongue thrust or thumb sucking can cause






15. 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






16. 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






17. 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






18. Posterior; no horizontal overlap






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






20. 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






21. Later






22. Curve spee & wilson - 3-d - not proven






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






24. 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






25. Teeth are misaligned when biting together






26. Maxillary - Mandibular - Facial






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






28. Mandibular molars and maxillary molars are even






29. Incisal 3rd






30. After periodontal sugery - mobility will ________






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






32. Abnormal contacts; occlusal habits - and neuroses






33. Buck teeth are common and are considered






34. 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






35. 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






36. Difference between primary and secondary occ trauma






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






38. Laterally






39. #10 & #23






40. Because the permanent premolars are narrower than the primary molars that they replace - this is what happens when the premolars erupt






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






42. Mandible moves to the right or left






43. Mesially - Labially






44. Tongue thrusting; thumb sucking - pacifiers






45. Spaces between two teeth






46. Horizontal






47. Maximum interlocking of cusp






48. Mandibular molars more distal than maxillary molars






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






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