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






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






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






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






5. Congenitally missing teeth - Impacted teeth & size and shape of muscle and bone






6. Widening of the PDL in areas under pressure results due to






7. ____ is not a sign of occl trauma






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






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






10. 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






11. 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






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






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






14. Abnormal contacts; occlusal habits - and neuroses






15. After periodontal sugery - mobility will ________






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






17. Lateral mvmt results in contacct of all posterior teeth






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






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






20. Maximum interlocking of cusp






21. Maxillary incisors are are lingual to mandibular incisors






22. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






23. #7 - 26 - 27






24. Associated with performance; all contacts during function of the oral cavity






25. Class III (mal)occlusion of permanent teeth






26. Rotated or twisted; rotated mesial or distal






27. Habitual - acquired - convenience - intercuspal & static






28. Functional occlusion






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






30. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






31. II (mal)occlusion






32. Starts closer to premolars






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






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






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






36. Posterior; no horizontal overlap






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






38. Measurement of horizontal overlap w/ probe






39. Spaces between two teeth






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






41. Occlusal guard =






42. Incisal 3rd






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






44. When no teeth are contacting on this side






45. Prognathic profile






46. Overlap of anterior teeth






47. Vertical






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






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






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