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






2. Anterior; no horizontal overlap






3. Buck teeth are common and are considered






4. Tooth positioned more lingual






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






6. Occlusal guard =






7. Starts around the mesial of the 1st molar






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






9. Mandible moves to the right or left






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






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






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






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






14. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






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






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






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






18. Laterally






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






20. When no teeth are contacting on this side






21. Maxillary overlap mandibular; whole arch






22. 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






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






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






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






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






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






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






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






30. Vertical overlapping






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






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






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






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






35. Middle 3rd






36. Congenitally missing teeth - Impacted teeth & size and shape of muscle and bone






37. Cervical 3rd






38. Later






39. Horizontal






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






41. Difference between primary and secondary occ trauma






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






43. Teeth are misaligned when biting together






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






45. Max canine occludes with mand. canine and mand. 1st premolar.






46. Horizontal distance of anterior teeth in crossbite






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






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






49. Functional occlusion






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