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. Tooth positioned more lingual






3. Maxillary overlap mandibular; whole arch






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






5. Mandibular molars and maxillary molars are even






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






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






8. Above occlusal plane






9. Abnormal contacts; occlusal habits - and neuroses






10. Curve of the occlusal plane; from anterior to posterior - increases with age






11. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






12. #7 - 26 - 27






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






14. Laterally






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






16. Posterior; no horizontal overlap






17. II (mal)occlusion






18. Maxillary anterior teeth stick out labially from tongue thrusting






19. Vertical






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






21. 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






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






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






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






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






26. Crowns tipped lingually - roots tipped laterally






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






28. Mandibular molars more mesial than maxillary molars (most children)






29. Later






30. Prognathic profile






31. When no teeth are contacting on this side






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






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






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






35. Tongue thrust or thumb sucking can cause






36. The tooth has insufficient bone support and normal chewing and swallowing forces are excessive - causing injury to the attachment appartatus






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






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






39. Class III (mal)occlusion of permanent teeth






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






41. Incisal 3rd






42. Relationship of the arches bone to bone;






43. Below occlusal plane






44. Both sides






45. Lateral mvmt results in contacct of all posterior teeth






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






47. Tooth extracted






48. 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






49. After periodontal sugery - mobility will ________






50. Horizontal
