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. Patients show evidence or signs and syptoms of occ disease






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






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






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






5. Anterior; no horizontal overlap






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






7. When no teeth are contacting on this side






8. Mandibular molars and maxillary molars are even






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






10. Tooth positioned more facial






11. Guidance for protrusive occ should be on the






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






13. Growth hormone imbalance that causes the mandible to grow faster than the maxilla(all teeth are in crossbite)






14. Teeth that are in func when the mandible moves in lateral or protrusive excursions or mvmts






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






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






17. Relationship of the arches bone to bone;






18. 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






19. Class III (mal)occlusion of permanent teeth






20. During a left working movement - the right side is known as the






21. Anterior teeth do not occlude - or remain open - while posterior teeth may have a normal occlusion






22. Tongue thrusting; thumb sucking - pacifiers






23. Incisal 3rd






24. Measurement of horizontal overlap w/ probe






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






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






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






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

30. Teeth are misaligned when biting together






31. Spaces between two teeth






32. Cervical 3rd






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






34. Retrognathic profile






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

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






38. Maxillary anterior teeth stick out labially from tongue thrusting
