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. 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






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






3. Measurement of horizontal overlap w/ probe






4. 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






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






6. Later






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






8. After periodontal sugery - mobility will ________






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






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






11. Overlap of anterior teeth






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






13. Maxillary - Mandibular - Facial






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






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






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






17. Both sides






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






19. #7 - 26 - 27






20. Selective grinding should always be completed after ______ has been controlled






21. High restoration - parafunctional habits - malpositioned tooth - periapical abcess - physical 'blow' - removable partial - ortho mvmt






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






23. Symptom free dentition that 'survives' or 'adapts' to a deviated occl






24. Maximum interlocking of cusp






25. Laterally






26. When no teeth are contacting on this side






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






28. Need tooth to tooth contact on both working and non working sides to func effectively






29. Vertical






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






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






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






33. 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






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






35. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






36. Vibrational mvmt of a tooth under occ function






37. Abnormal contacts; occlusal habits - and neuroses






38. Tongue thrust or thumb sucking can cause






39. Middle 3rd






40. Teeth are misaligned when biting together






41. Curve of the occlusal plane; from anterior to posterior - increases with age






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






43. Radiographically - the PDL space is wider at the coronal third of the root






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






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






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






47. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






48. Above occlusal plane






49. Tooth positioned more facial






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