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






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






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






4. Cervical 3rd






5. Spaces between two teeth






6. Anterior; no horizontal overlap






7. Both sides






8. Tongue thrust or thumb sucking can cause






9. Tooth positioned more lingual






10. Curve of the occlusal plane; from anterior to posterior - increases with age






11. Functional occlusion






12. Excessive occ force with adequate bone support =






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






14. Tooth extracted






15. Starts around the mesial of the 1st molar






16. Maximum interlocking of cusp






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






18. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






19. Measurement of horizontal overlap w/ probe






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. Introduced the concept of codestruction






22. Crowns tipped lingually - roots tipped laterally






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






24. Vertical






25. Excessive deposition of cementum around the apex - due to excessive occlusal forces






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






27. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






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






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






30. #10 & #23






31. Mandibular molars and maxillary molars are even






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






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






34. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






35. Tongue thrusting; thumb sucking - pacifiers






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






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






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






39. Slight buccal inclination of crown - lingual inclination of root






40. When no teeth are contacting on this side






41. Occlusal guard =






42. After periodontal sugery - mobility will ________






43. Primary teeth set ___________________ for permanent






44. Starts closer to premolars






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






46. #7 - 26 - 27






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






48. Rotated or twisted; rotated mesial or distal






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






50. Starts closer to the posterior of the 1st molar
