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. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






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






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






4. Rotated or twisted; rotated mesial or distal






5. Mandibular molars more distal than maxillary molars






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






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






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






9. Functional occlusion






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






11. Later






12. Guidance for protrusive occ should be on the






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






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






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






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






17. Position of the mandible relative to the maxilla during swallowing and other times when the jaw muscles contract






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






19. Primary teeth set ___________________ for permanent






20. The side to which the mandible moves(chewing side)






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






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






23. Anterior; no horizontal overlap






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






25. Vertical






26. Maxillary incisors are are lingual to mandibular incisors






27. ____ is not a sign of occl trauma






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






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






30. After periodontal sugery - mobility will ________






31. If the mandible moves to the left - the mvmt is known as a left working movement






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






33. Retrognathic profile






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






35. Cervical 3rd






36. Measurement of horizontal overlap w/ probe






37. Excessive occ force with adequate bone support =






38. 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






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






40. 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






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






42. Incisal 3rd






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






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






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






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






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






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






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






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