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






2. Teeth are misaligned when biting together






3. Relationship of the teeth in which the incisal ridges of the maxillary anterior teeth extend below the incisal edges of the mandibular anterior teeth when the teeth are placed in a centric occlusal relationship






4. Vertical






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






6. Horizontal distance of anterior teeth in crossbite






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






8. Laterally






9. 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






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






11. Horizontal






12. Primary teeth set ___________________ for permanent






13. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






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






15. Occlusal guard =






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






17. What is not affected by occ trauma






18. Individual teeth from each arch can be involved in ________________ malocclusion






19. Lateral mvmt results in contacct of all posterior teeth






20. ____ is not a sign of occl trauma






21. Both sides






22. Starts around the mesial of the 1st molar






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






24. 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






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






26. Maxillary - Mandibular - Facial






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






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






29. Later






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






31. Mandibular molars more distal than maxillary molars






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






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






34. Below occlusal plane






35. Mesially - Labially






36. The tooth has insufficient bone support and normal chewing and swallowing forces are excessive - causing injury to the attachment appartatus






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






38. Relationship of the arches bone to bone;






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






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






41. Abnormal contacts; occlusal habits - and neuroses






42. Curve spee & wilson - 3-d - not proven






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






44. Spaces between two teeth






45. The relationship of the teeth in the mandibular arch to those in the maxillary arch as they are brought together






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






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






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






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






50. Habitual - acquired - convenience - intercuspal & static
