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






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






3. Later






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






5. After periodontal sugery - mobility will ________






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






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






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






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






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






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






12. Can affect the TMJ - muscles of mastication - pulp and integrity of restorations






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






14. Abnormal contacts; occlusal habits - and neuroses






15. Starts closer to premolars






16. Survival of the dentition despite its deviation from a preconceived hypothetical normal






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






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






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






20. Mandible moves to the right or left






21. Most retruded position of the mandible in relation to the maxilla From which lateral mvmts of the jaw can be made






22. Difference between primary and secondary occ trauma






23. II (mal)occlusion






24. Crowns tipped lingually - roots tipped laterally






25. Curve spee & wilson - 3-d - not proven






26. What is not affected by occ trauma






27. Mesially - Labially






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






29. Guidance for protrusive occ should be on the






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






31. Posterior; no horizontal overlap






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






33. Introduced the concept of codestruction






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






35. Lateral mvmt results in contacct of all posterior teeth






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






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






38. Reshaping of the occ or incisal surfaces of teeth to create contacts btwn upper and lower dentition






39. Rotated or twisted; rotated mesial or distal






40. Excessive occ force with adequate bone support =






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






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






43. Maximum interlocking of cusp






44. Max canine occludes with mand. canine and mand. 1st premolar.






45. Spaces between two teeth






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






47. Measurement of horizontal overlap w/ probe






48. 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






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






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