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. Injury to the attachment apparatus (bone - PDL - and cementum) as a consequence of normal or excessive occ forces






2. Vertical






3. Functional occlusion






4. Mandible moves to the right or left






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






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






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






8. 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






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






10. Crowns tipped lingually - roots tipped laterally






11. After periodontal sugery - mobility will ________






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






13. Mandibular molars and maxillary molars are even






14. Class III (mal)occlusion of permanent teeth






15. The way you normally bite your teeth together when not chewing






16. Maximum interlocking of cusp






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






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






19. 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






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






21. Excessive occ force with adequate bone support =






22. Prognathic profile; buccal groove of mand. 1st molar-mesial to mb cusp of max. 1st molar; distal of mand. canine mesial to mesial of max canine; tendency toward class III






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






24. Tooth extracted






25. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious






26. Most common cause is when the maxilla does not grow in proportion to the mandible






27. Later






28. When no teeth are contacting on this side






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






30. #10 & #23






31. Horizontal






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






33. Teeth that are in func when the mandible moves in lateral or protrusive excursions or mvmts






34. Difference between primary and secondary occ trauma






35. 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






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






37. Tooth positioned more lingual






38. Tongue thrust or thumb sucking can cause






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






40. Slight buccal inclination of crown - lingual inclination of root






41. Mesognathic profile






42. ____ is not a sign of occl trauma






43. Mesially - Labially






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






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






46. Rotated or twisted; rotated mesial or distal






47. Spaces between two teeth






48. Both sides






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






50. Maxillary overlap mandibular; whole arch
