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. Normal contacts between max. and mand. teeth; momentary contacts






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






3. Introduced the concept of codestruction






4. Anterior; no horizontal overlap






5. Vertical overlapping






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






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






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






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






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






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






12. Guidance for protrusive occ should be on the






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






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






15. The patient is constantly tightening the lower lip against the lower anterior teeth causing the the mandibular teeth to be pushed back into the mouth by this overdeveloped lower lip






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






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






18. Tooth positioned more facial






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






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






21. The tooth has insufficient bone support and normal chewing and swallowing forces are excessive - causing injury to the attachment appartatus






22. Maximum touching of max and mand






23. Mesially - Labially






24. The way you normally bite your teeth together when not chewing






25. Mandible moves to the right or left






26. Later






27. Incisal 3rd






28. Mesognathic profile






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






30. Horizontal






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






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






33. Rotated or twisted; rotated mesial or distal






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






35. Tongue thrusting; thumb sucking - pacifiers






36. 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






37. Mb cusp of max 1st molar-buccal groove of mand 1st molar






38. Maxillary - Mandibular - Facial






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






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






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






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






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






44. Cervical 3rd






45. Difference between primary and secondary occ trauma






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






47. Horizontal distance of anterior teeth in crossbite






48. Symptom free dentition that 'survives' or 'adapts' to a deviated occl






49. Maximum interlocking of cusp






50. 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
