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. Laterally






2. Cervical 3rd






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






4. Horizontal






5. Maxillary overlap mandibular; whole arch






6. Lateral mvmt results in contacct of all posterior teeth






7. Tongue thrust or thumb sucking can cause






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






9. Tooth positioned more lingual






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






11. Maxillary - Mandibular - Facial






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






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






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






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






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






17. Teeth are misaligned when biting together






18. Survival of the dentition despite its deviation from a preconceived hypothetical normal






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






20. Primary teeth set ___________________ for permanent






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






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






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






24. Both sides






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






26. Tooth positioned more facial






27. Below occlusal plane






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






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






30. Guidance for protrusive occ should be on the






31. Occlusal guard =






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






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






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






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






36. 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






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






38. Overlap of anterior teeth






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






40. Tooth extracted






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






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






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






44. Rotated or twisted; rotated mesial or distal






45. Abnormal contacts; occlusal habits - and neuroses






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






47. When no teeth are contacting on this side






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






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






50. Normal contacts between max. and mand. teeth; momentary contacts
