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. Maximum touching of max and mand






2. Slight buccal inclination of crown - lingual inclination of root






3. Horizontal distance of anterior teeth in crossbite






4. Measurement of horizontal overlap w/ probe






5. Prognathic profile






6. Vertical overlapping






7. Anterior; no horizontal overlap






8. Incisal 3rd






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






10. Spaces between two teeth






11. Below occlusal plane






12. Mandibular molars more distal than maxillary molars






13. Horizontal






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






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






16. When no teeth are contacting on this side






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






18. Middle 3rd






19. Laterally






20. Later






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






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






23. 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






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






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






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






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






28. Retrognathic profile






29. Starts around the mesial of the 1st molar






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






31. Vertical






32. #10 & #23






33. Tongue thrust or thumb sucking can cause






34. Excessive deposition of cementum around the apex - due to excessive occlusal forces






35. Lateral mvmt results in contacct of all posterior teeth






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






37. 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






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






39. The side to which the mandible moves(chewing side)






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






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






42. 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






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






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






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






46. Injury to the attachment apparatus (bone - PDL - and cementum) as a consequence of normal or excessive occ forces






47. 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






48. Guidance for protrusive occ should be on the






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






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