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






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






3. 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






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






5. Guidance for protrusive occ should be on the






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






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






8. Teeth that are in func when the mandible moves in lateral or protrusive excursions or mvmts






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






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






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






12. Buck teeth are common and are considered






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






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






15. 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






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






17. Prognathic profile; buccal groove of mand. 1st molar-mesial to mb cusp of max. 1st molar; distal of mand. canine mesial to mesial of max canine; tendency toward class III






18. Excessive deposition of cementum around the apex - due to excessive occlusal forces






19. Excessive occ force with adequate bone support =






20. Maxillary overlap mandibular; whole arch






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






22. When no teeth are contacting on this side






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






24. Vertical overlapping






25. Mandibular molars and maxillary molars are even






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






27. Maximum interlocking of cusp






28. Mesially - Labially






29. ____ is not a sign of occl trauma






30. Laterally






31. Mesognathic profile






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






33. Occlusal guard =






34. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






35. Maxillary anterior teeth stick out labially from tongue thrusting






36. Mandible moves to the right or left






37. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






38. Maxillary incisors are are lingual to mandibular incisors






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






40. Above occlusal plane






41. Difference between primary and secondary occ trauma






42. Habitual - acquired - convenience - intercuspal & static






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






44. Maxillary - Mandibular - Facial






45. 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






46. 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






47. Below occlusal plane






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






49. Starts closer to premolars






50. Maximum touching of max and mand
