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. Lateral mvmt results in contacct of all posterior teeth






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






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






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






5. Introduced the concept of codestruction






6. Horizontal distance of anterior teeth in crossbite






7. Laterally






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






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






10. II (mal)occlusion






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






12. Maxillary - Mandibular - Facial






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






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






15. Tooth extracted






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






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






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






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






20. Difference between primary and secondary occ trauma






21. Rotated or twisted; rotated mesial or distal






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






23. Starts around the mesial of the 1st molar






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






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






26. Prognathic profile; buccal groove of mand. 1st molar-mesial to mb cusp of max. 1st molar; distal of mand. canine mesial to mesial of max canine; tendency toward class III






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






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






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






31. Vertical overlapping






32. Mesognathic profile






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






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






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






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






37. Guidance for protrusive occ should be on the






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






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






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






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






42. Habitual - acquired - convenience - intercuspal & static






43. Maxillary-between canines and laterals - mandibular-between canines and 1st molars






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






45. Relationship of the teeth in which the incisal ridges of the maxillary anterior teeth extend below the incisal edges of the mandibular anterior teeth when the teeth are placed in a centric occlusal relationship






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






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






48. Maximum touching of max and mand






49. Tooth positioned more lingual






50. 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
