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






2. Vibrational mvmt of a tooth under occ function






3. Functional occlusion






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






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






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






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






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






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






10. Abnormal contacts; occlusal habits - and neuroses






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






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






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






14. Horizontal distance of anterior teeth in crossbite






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






16. Retrognathic profile






17. #10 & #23






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






19. Tongue thrust or thumb sucking can cause






20. Crowns tipped lingually - roots tipped laterally






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






22. Lateral mvmt results in contacct of all posterior teeth






23. Tooth extracted






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






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






26. 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






27. 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






28. During protrusive occ - ______ is considered undesirable






29. Maximum interlocking of cusp






30. Guidance for protrusive occ should be on the






31. Maxillary overlap mandibular; whole arch






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






33. Maximum touching of max and mand






34. Spaces between two teeth






35. Posterior; no horizontal overlap






36. Primary teeth set ___________________ for permanent






37. Anterior; no horizontal overlap






38. After periodontal sugery - mobility will ________






39. Malposition - crowded anterior teeth - protruded or retruded max incisors - anterior/posterior crossbite - mesial drift






40. 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






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






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






43. II (mal)occlusion






44. Excessive occ force with adequate bone support =






45. Mesognathic profile






46. Tooth positioned more lingual






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






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






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






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