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






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






3. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






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






5. Maxillary incisors are are lingual to mandibular incisors






6. Tongue thrust or thumb sucking can cause






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






8. Incisal 3rd






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






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






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






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






13. Tooth positioned more lingual






14. Relationship of the teeth in opposite arches; static position






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






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






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






18. 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






19. Horizontal distance of anterior teeth in crossbite






20. Mandibular molars and maxillary molars are even






21. #10 & #23






22. Introduced the concept of codestruction






23. Prognathic profile






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






25. Mandibular molars more distal than maxillary molars






26. Class III (mal)occlusion of permanent teeth






27. When no teeth are contacting on this side






28. Difference between primary and secondary occ trauma






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






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






31. Mobility - migration - pain - premature contact - widening of PDL - parafuntional habits - TMJ problems - all result in _________






32. During protrusive occ - ______ is considered undesirable






33. Below occlusal plane






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






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






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






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






38. Vertical overlapping






39. Laterally






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






41. Crowns tipped lingually - roots tipped laterally






42. Permits healing of the attachment apparatus by holding a tooth in a totally fixed position; allows the PDL to become narrower and the mobility to be reduced






43. Mand. retruded-max. incisors protruded; deep overbite; excessive overjet - abnormal muscle function - short mandible - short upper lip






44. Because the permanent premolars are narrower than the primary molars that they replace - this is what happens when the premolars erupt






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






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






47. Vertical






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






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






50. #7 - 26 - 27
