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






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






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






4. Anterior teeth do not occlude - or remain open - while posterior teeth may have a normal occlusion






5. #10 & #23






6. Normal contacts between max. and mand. teeth; momentary contacts






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






8. Measurement of horizontal overlap w/ probe






9. Abnormal contacts; occlusal habits - and neuroses






10. Crowns tipped lingually - roots tipped laterally






11. Mesially - Labially






12. 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






13. Occlusal guard =






14. Lateral mvmt results in contacct of all posterior teeth






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






16. Tooth extracted






17. Middle 3rd






18. 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






19. Tooth positioned more facial






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






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






22. Horizontal






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






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






25. II (mal)occlusion






26. Both sides






27. During a left working movement - the right side is known as the






28. 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






29. Radiographically - the PDL space is wider at the coronal third of the root






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






31. Selective grinding should always be completed after ______ has been controlled






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






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






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






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






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






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






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






39. Spaces between two teeth






40. Tongue thrusting; thumb sucking - pacifiers






41. 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






42. Difference between primary and secondary occ trauma






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






44. Vibrational mvmt of a tooth under occ function






45. Can affect the TMJ - muscles of mastication - pulp and integrity of restorations






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






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






48. Buck teeth are common and are considered






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






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