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. 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






2. II (mal)occlusion






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






4. Vertical






5. Occlusal guard =






6. Horizontal






7. Mandibular molars more distal than maxillary molars






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






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






10. Maxillary overlap mandibular; whole arch






11. Crowns tipped lingually - roots tipped laterally






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






13. Maximum touching of max and mand






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






15. Teeth are misaligned when biting together






16. Buck teeth are common and are considered






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






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






19. Lateral mvmt results in contacct of all posterior teeth






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






21. Maximum interlocking of cusp






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






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






24. Maxillary incisors are are lingual to mandibular incisors






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






26. What is not affected by occ trauma






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






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






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






30. Laterally






31. Retrognathic profile






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






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






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






35. Maxillary anterior teeth stick out labially from tongue thrusting






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






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






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






39. Rotated or twisted; rotated mesial or distal






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






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






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






43. Tooth extracted






44. Guidance for protrusive occ should be on the






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






46. Abnormal contacts; occlusal habits - and neuroses






47. Tongue thrust or thumb sucking can cause






48. Primary teeth set ___________________ for permanent






49. Starts closer to premolars






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