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. Vertical






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






3. Relationship of the arches bone to bone;






4. Mvmt of the mandible in a direction anterior to centric occ






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






6. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






7. 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






8. Vertical overlapping






9. Buck teeth are common and are considered






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






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






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






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






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






15. Mand. retruded-max. incisors protruded; deep overbite; excessive overjet - abnormal muscle function - short mandible - short upper lip






16. Maximum touching of max and mand






17. When no teeth are contacting on this side






18. Starts around the mesial of the 1st molar






19. Posterior; no horizontal overlap






20. Tooth positioned more facial






21. #10 & #23






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






23. 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






24. Tooth positioned more lingual






25. Tooth extracted






26. #7 - 26 - 27






27. Cusps of maxillary teeth directly over cusps of mandibular teeth






28. Later






29. Mobility - migration - pain - premature contact - widening of PDL - parafuntional habits - TMJ problems - all result in _________






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






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






32. Mesially - Labially






33. Prognathic profile






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






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






36. During protrusive occ - ______ is considered undesirable






37. Maxillary incisors are are lingual to mandibular incisors






38. 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






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






40. Excessive occ force with adequate bone support =






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






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






43. Both sides






44. Overlap of anterior teeth






45. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






46. Tongue thrust or thumb sucking can cause






47. Introduced the concept of codestruction






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






49. Vibrational mvmt of a tooth under occ function






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