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






2. Mobility - migration - pain - premature contact - widening of PDL - parafuntional habits - TMJ problems - all result in _________






3. #10 & #23






4. Teeth are misaligned when biting together






5. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






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






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






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






9. Rotated or twisted; rotated mesial or distal






10. Vibrational mvmt of a tooth under occ function






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






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






13. Malocclusion cause excessive incisal or occlusal wear(attrition); teeth continue to erupt in order to occlude with teeth in the opposite arch & roots become exposed






14. Spaces between two teeth






15. Introduced the concept of codestruction






16. Prognathic profile






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






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






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






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






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






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






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






24. Retrognathic profile






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






26. Starts around the mesial of the 1st molar






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






28. Cervical 3rd






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






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






31. ____ is not a sign of occl trauma






32. Horizontal distance of anterior teeth in crossbite






33. Tooth extracted






34. Both sides






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






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






37. Mandibular molars more distal than maxillary molars






38. Maximum touching of max and mand






39. Occlusal guard =






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






41. Relationship of the arches bone to bone;






42. Crowns tipped lingually - roots tipped laterally






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






44. Tooth positioned more lingual






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






46. Functional occlusion






47. Maximum interlocking of cusp






48. Overlap of anterior teeth






49. Incisal 3rd






50. Anterior; no horizontal overlap
