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






2. 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






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






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






5. Tooth positioned more lingual






6. The way you normally bite your teeth together when not chewing






7. Teeth are misaligned when biting together






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






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






10. Maxillary - Mandibular - Facial






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






12. Vertical






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






14. Patients show evidence or signs and syptoms of occ disease






15. Occlusal guard =






16. Tooth positioned more facial






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






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






19. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






20. Mand. retruded-one or more max. incisors retruded; max. laterals protruded-max centrals retruded; crowded max anterior teeth; deep overbite






21. Vertical overlapping






22. Mandibular molars and maxillary molars are even






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






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






25. Incisal 3rd






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






27. 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






28. Vibrational mvmt of a tooth under occ function






29. Anterior; no horizontal overlap






30. Crowns tipped lingually - roots tipped laterally






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






32. Lateral mvmt results in contacct of all posterior teeth






33. Below occlusal plane






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






35. Spaces between two teeth






36. Mandible moves to the right or left






37. Later






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






39. Maxillary overlap mandibular; whole arch






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






41. When no teeth are contacting on this side






42. Measurement of horizontal overlap w/ probe






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






44. 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






45. Excessive occ force with adequate bone support =






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






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






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






49. Overlap of anterior teeth






50. 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
