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. Horizontal distance of anterior teeth in crossbite






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






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






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






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






6. Both sides






7. Mandibular molars more distal than maxillary molars






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






9. Cusps of maxillary teeth directly over cusps of mandibular teeth






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






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






12. Anterior; no horizontal overlap






13. Lateral mvmt results in contacct of all posterior teeth






14. Need tooth to tooth contact on both working and non working sides to func effectively






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






16. Abnormal contacts; occlusal habits - and neuroses






17. Mandibular molars and maxillary molars are even






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






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






20. Buck teeth are common and are considered






21. Difference between primary and secondary occ trauma






22. 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






23. Primary teeth set ___________________ for permanent






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






25. Vertical overlapping






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






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

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






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






34. II (mal)occlusion






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






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

39. Middle 3rd






40. Relationship of the arches bone to bone;






41. Horizontal

43. Measurement of horizontal overlap w/ probe






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






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






46. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






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






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






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