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






2. ____ is not a sign of occl trauma






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






4. #7 - 26 - 27






5. Retrognathic profile






6. 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






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






8. Horizontal distance of anterior teeth in crossbite






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






10. 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






11. Guidance for protrusive occ should be on the






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






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






14. 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






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






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






17. Cervical 3rd






18. 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






19. Occlusal guard =






20. Maxillary anterior teeth stick out labially from tongue thrusting






21. Tooth extracted






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






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






24. Difference between primary and secondary occ trauma






25. Above occlusal plane






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






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






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






29. Later






30. Mesially - Labially






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






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






33. Maxillary - Mandibular - Facial






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






35. Buck teeth are common and are considered






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






37. 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






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






39. Maxillary overlap mandibular; whole arch






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






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






42. Mandible moves to the right or left






43. Incisal 3rd






44. Lateral mvmt results in contact btwn the max and mand canines






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






46. Overlap of anterior teeth






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






48. Primary teeth set ___________________ for permanent






49. Tooth positioned more lingual






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