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






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






3. Tooth extracted






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






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






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






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






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






9. Spaces between two teeth






10. Starts closer to the posterior of the 1st molar






11. Maxillary incisors are are lingual to mandibular incisors






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






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






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






15. Anterior; no horizontal overlap






16. Maxillary - Mandibular - Facial






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






18. Associated with performance; all contacts during function of the oral cavity






19. 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






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






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






22. Above occlusal plane






23. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious






24. Tooth positioned more lingual






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






26. 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






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






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






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






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






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






32. Prognathic profile






33. Mesognathic profile






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






35. Class III (mal)occlusion of permanent teeth






36. Maximal intercuspation or contact of the max and mand teeth






37. 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






38. Teeth are misaligned when biting together






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






40. Maxillary anterior teeth stick out labially from tongue thrusting






41. Measurement of horizontal overlap w/ probe






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






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






44. Starts closer to premolars






45. Tongue thrusting; thumb sucking - pacifiers






46. Cervical 3rd






47. Both sides






48. Below occlusal plane






49. Horizontal






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