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






2. Overlap of anterior teeth






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






4. 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






5. Prognathic profile

7. Anterior; no horizontal overlap






8. Vertical overlapping






9. Maxillary incisors are are lingual to mandibular incisors






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






11. #7 - 26 - 27






12. Retrognathic profile; buccal groove of mand 1st molar-distal to mb cusp of max 1st; distal of mand. canine distal to mesial to max caniine - tendency toward class II






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






14. Lateral mvmt results in contacct of all posterior teeth






15. Patients show evidence or signs and syptoms of occ disease






16. Tooth positioned more facial






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






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






19. Radiographically - the PDL space is wider at the coronal third of the root






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






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






22. Occlusal guard =






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






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






25. 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

30. Difference between primary and secondary occ trauma






31. During protrusive occ - ______ is considered undesirable






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






33. Permits healing of the attachment apparatus by holding a tooth in a totally fixed position; allows the PDL to become narrower and the mobility to be reduced






34. Below occlusal plane






35. ____ is not a sign of occl trauma






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






37. Retrognathic profile






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






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






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






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






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