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; no horizontal overlap






2. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






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






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






5. Maximal intercuspation or contact of the max and mand teeth






6. Mvmt of the mandible in a direction anterior to centric occ






7. Maximum touching of max and mand






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






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






10. What is not affected by occ trauma






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






12. Cusps of maxillary teeth directly over cusps of mandibular teeth






13. After periodontal sugery - mobility will ________






14. Maximum interlocking of cusp






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






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






17. Below occlusal plane






18. Mand. retruded-max. incisors protruded; deep overbite; excessive overjet - abnormal muscle function - short mandible - short upper lip






19. Spaces between two teeth






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






21. Both sides






22. Teeth are misaligned when biting together






23. Maxillary anterior teeth stick out labially from tongue thrusting






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






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






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






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






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






29. #7 - 26 - 27






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






31. ____ is not a sign of occl trauma






32. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






33. Above occlusal plane






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






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






36. Primary teeth set ___________________ for permanent






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






38. Introduced the concept of codestruction






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






40. Posterior; no horizontal overlap






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






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






43. 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






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






45. II (mal)occlusion
