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. Prognathic profile






2. Mandibular molars and maxillary molars are even






3. Primary teeth set ___________________ for permanent






4. Cervical 3rd






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






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






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






8. Posterior; no horizontal overlap






9. Retrognathic profile






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






11. Starts closer to premolars






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






13. Measurement of horizontal overlap w/ probe






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






15. Mesially - Labially






16. Starts around the mesial of the 1st molar






17. Mesognathic profile






18. Tooth positioned more lingual






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






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






21. Tooth extracted






22. Vibrational mvmt of a tooth under occ function






23. Spaces between two teeth






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






25. #10 & #23






26. 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






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






28. Above occlusal plane






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






30. Tongue thrusting; thumb sucking - pacifiers






31. Buck teeth are common and are considered






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






33. Horizontal






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






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






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






37. #7 - 26 - 27






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






39. Maximum interlocking of cusp






40. Maxillary - Mandibular - Facial






41. Anterior; no horizontal overlap






42. Retrognathic profile; buccal groove of mand 1st molar-distal to mb cusp of max 1st; distal of mand. canine distal to mesial to max caniine - tendency toward class II






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






44. Functional occlusion






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






46. Occlusal guard =






47. Later






48. Guidance for protrusive occ should be on the






49. Introduced the concept of codestruction






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