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. Below occlusal plane






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






3. High restoration - parafunctional habits - malpositioned tooth - periapical abcess - physical 'blow' - removable partial - ortho mvmt






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






5. Laterally






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






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






8. Teeth are misaligned when biting together






9. Above occlusal plane






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






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






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






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






14. Maxillary - Mandibular - Facial






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






16. Introduced the concept of codestruction






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






18. Maxillary incisors are are lingual to mandibular incisors






19. Starts closer to premolars






20. 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






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






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






23. ____ is not a sign of occl trauma






24. Maximum touching of max and mand






25. Vertical overlapping






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






27. When no teeth are contacting on this side






28. Maxillary anterior teeth stick out labially from tongue thrusting






29. Functional occlusion






30. Tongue thrusting; thumb sucking - pacifiers






31. Position of the mandible relative to the maxilla during swallowing and other times when the jaw muscles contract






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






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






34. 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






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






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






37. Tooth positioned more facial






38. Anterior crossbite; max/mand incisors-edge to edge occlusion; crowded mand. incisors






39. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






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






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






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






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






44. Anterior; no horizontal overlap






45. Habitual - acquired - convenience - intercuspal & static






46. 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






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






48. Horizontal






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






50. Mandibular molars more distal than maxillary molars
