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






2. Vibrational mvmt of a tooth under occ function






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






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






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






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






7. Mandibular molars more distal than maxillary molars






8. Teeth are misaligned when biting together






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






10. Curved alignment of the occlusal plane when looking from a posterior view(right to left)






11. Cervical 3rd






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






13. Introduced the concept of codestruction






14. Spaces between two teeth






15. Starts closer to premolars






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






17. Abnormal contacts; occlusal habits - and neuroses






18. Tongue thrust or thumb sucking can cause






19. Usually indicative of moderate to sever perio and secondary occ trauma






20. 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






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






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






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






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






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






26. Vertical overlapping






27. Maxillary incisors are are lingual to mandibular incisors






28. Tooth positioned more lingual






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






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






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






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






33. #10 & #23






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






35. Mobility - migration - pain - premature contact - widening of PDL - parafuntional habits - TMJ problems - all result in _________






36. Horizontal






37. Maxillary overlap mandibular; whole arch






38. Prognathic profile






39. #7 - 26 - 27






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






41. Maximum touching of max and mand






42. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation






43. 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






44. ____ is not a sign of occl trauma






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






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






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






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






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






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