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. Retrognathic profile; buccal groove of mand 1st molar-distal to mb cusp of max 1st; distal of mand. canine distal to mesial to max caniine - tendency toward class II






2. Vertical overlapping






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






4. Tooth extracted






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






6. Tooth positioned more lingual






7. Difference between primary and secondary occ trauma






8. Maxillary overlap mandibular; whole arch






9. When no teeth are contacting on this side






10. Anterior; no horizontal overlap






11. Prognathic profile






12. 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






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






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






15. Excessive occ force with adequate bone support =






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






17. Hereditary - Tongue - Intercuspation of teeth - Alignment of previously erupted teeth affects alignment of successive teeth






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






19. Functional occlusion






20. Starts around the mesial of the 1st molar






21. Class III (mal)occlusion of permanent teeth






22. #10 & #23






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






24. Mb cusp of max 1st molar-buccal groove of mand 1st molar






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






26. 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






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






28. Mesially - Labially






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






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






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






32. Retrognathic profile -buccal groove of mand. 1st molar-distal to mb cusp of 1st max.molar -distal of mand canine distal to mesial of max canine - tendency towards class II






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






34. Both sides






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






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






37. Retrognathic profile






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






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






40. What is not affected by occ trauma






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






42. During protrusive occ - ______ is considered undesirable






43. Tongue thrusting; thumb sucking - pacifiers






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






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






46. 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






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






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






49. A continuation of the spee of to extend through the condyle






50. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation
