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






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






3. Mandibular molars more distal than maxillary molars






4. After periodontal sugery - mobility will ________






5. Maxillary overlap mandibular; whole arch






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






7. Tongue thrusting; thumb sucking - pacifiers






8. Laterally






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






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






11. Max canine occludes with mand. canine and mand. 1st premolar.






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






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






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






15. Horizontal






16. Measurement of horizontal overlap w/ probe






17. Mandibular molars and maxillary molars are even






18. Spaces between two teeth






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






20. Horizontal distance of anterior teeth in crossbite






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






22. Middle 3rd






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






24. 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






25. Retrognathic profile






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






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






28. Posterior; no horizontal overlap






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






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






31. Anterior; no horizontal overlap






32. During protrusive occ - ______ is considered undesirable






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






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






35. Tooth positioned more lingual






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






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






38. Tooth positioned more facial






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






40. Relationship of the arches bone to bone;






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






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






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






44. Class III (mal)occlusion of permanent teeth






45. Abnormal contacts; occlusal habits - and neuroses






46. Vertical overlapping






47. Maxillary - Mandibular - Facial






48. Rotated or twisted; rotated mesial or distal






49. 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






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