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






2. 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






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






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






5. Lateral mvmt results in contacct of all posterior teeth






6. Buck teeth are common and are considered






7. 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






8. After periodontal sugery - mobility will ________






9. Starts closer to premolars






10. #10 & #23






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






12. #7 - 26 - 27






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






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






15. Vertical






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






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






18. Tooth extracted






19. Crowns tipped lingually - roots tipped laterally






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






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






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






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






24. Both sides






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






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






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






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






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






30. Later






31. Measurement of horizontal overlap w/ probe






32. Laterally






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






34. 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






35. 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






36. Incisal 3rd






37. Cervical 3rd






38. Habitual - acquired - convenience - intercuspal & static






39. Horizontal






40. Starts around the mesial of the 1st molar






41. Introduced the concept of codestruction






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






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






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






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






46. Maxillary incisors are are lingual to mandibular incisors






47. Mesially - Labially






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






49. High restoration - parafunctional habits - malpositioned tooth - periapical abcess - physical 'blow' - removable partial - ortho mvmt






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