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






2. Retrognathic profile






3. Lateral mvmt results in contacct of all posterior teeth






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






5. 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






6. Tooth positioned more facial






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






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






9. Horizontal distance of anterior teeth in crossbite






10. 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






11. Excessive occ force with adequate bone support =






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






13. Relationship of the arches bone to bone;






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






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






16. Starts around the mesial of the 1st molar






17. Above occlusal plane






18. Malocclusion cause excessive incisal or occlusal wear(attrition); teeth continue to erupt in order to occlude with teeth in the opposite arch & roots become exposed






19. Guidance for protrusive occ should be on the






20. Vertical overlapping






21. Tooth-tooth contacts; tooth-hard objects contacts; tooth-oral tissues contact






22. When no teeth are contacting on this side






23. Teeth are misaligned when biting together






24. Mesially - Labially






25. Muscles that work the jaw; may become sore due to occ trauma






26. Individual teeth from each arch can be involved in ________________ malocclusion






27. Maximum interlocking of cusp






28. Anterior; no horizontal overlap






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






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






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






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






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






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






35. Introduced the concept of codestruction






36. Crowns tipped lingually - roots tipped laterally






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






38. Functional occlusion






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






40. Maxillary incisors are are lingual to mandibular incisors






41. Mand. retruded-one or more max. incisors retruded; max. laterals protruded-max centrals retruded; crowded max anterior teeth; deep overbite






42. Posterior; no horizontal overlap






43. Maxillary overlap mandibular; whole arch






44. Later






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






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






47. Prognathic profile






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






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