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






2. Guidance for protrusive occ should be on the






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






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






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






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






7. Teeth are misaligned when biting together






8. Maxillary - Mandibular - Facial






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






10. Horizontal






11. Relationship of the arches bone to bone;






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






13. Maximum interlocking of cusp






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






15. Functional occlusion






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






17. 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






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






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






20. Vertical






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






22. 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






23. 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






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






25. Tooth positioned more facial






26. Horizontal distance of anterior teeth in crossbite






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






28. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious






29. Mandibular molars and maxillary molars are even






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






31. 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






32. Below occlusal plane






33. Tooth-tooth contacts; tooth-hard objects contacts; tooth-oral tissues contact






34. Tongue thrust or thumb sucking can cause

42. Tooth extracted






43. Incisal 3rd






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






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






46. Spaces between two teeth






47. Mandibular molars more distal than maxillary molars






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






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






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