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. Abnormal contacts; occlusal habits - and neuroses






2. Relationship of the arches bone to bone;






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






4. Incisal 3rd






5. Middle 3rd






6. II (mal)occlusion






7. Anterior or posterior; bilateral or unitlateral - anterior more common






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






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






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






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






12. Primary teeth set ___________________ for permanent






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






14. Mandibular molars more distal than maxillary molars






15. Retrognathic profile






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






17. Maximum touching of max and mand






18. Cervical 3rd






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






20. Overlap of anterior teeth






21. Horizontal distance of anterior teeth in crossbite






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






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






24. Patient forces teeth together in centric occlusion on one side to get a more functional bite and has a crossbite on the other side(the midline of the maxillary anterior teeth does not line up with the midlineof the mandible






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






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






27. #10 & #23






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






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






30. Maximum interlocking of cusp






31. Tooth positioned more lingual






32. Maxillary-between canines and laterals - mandibular-between canines and 1st molars






33. Starts around the mesial of the 1st molar






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






35. Maxillary incisors are are lingual to mandibular incisors






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






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






38. Later






39. Habitual - acquired - convenience - intercuspal & static






40. Tongue thrust or thumb sucking can cause






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






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






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






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






45. Lateral mvmt results in contacct of all posterior teeth






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






47. Mesially - Labially






48. Aquired centric occlusion - habitual occlusion - convienience occlusion - or intercuspal position






49. During selective grinding - occlusion should be adjusted In what four relationships






50. Tooth-tooth contacts; tooth-hard objects contacts; tooth-oral tissues contact
