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. Tooth positioned more facial






2. Buck teeth are common and are considered






3. Mesognathic profile






4. Maximum touching of max and mand






5. Tongue thrust or thumb sucking can cause






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






7. Lateral mvmt results in contacct of all posterior teeth






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. Anterior teeth do not occlude - or remain open - while posterior teeth may have a normal occlusion






11. Maxillary overlap mandibular; whole arch






12. 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






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






14. Teeth are misaligned when biting together






15. Mand. retruded-one or more max. incisors retruded; max. laterals protruded-max centrals retruded; crowded max anterior teeth; deep overbite






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






17. ____ is not a sign of occl trauma






18. Crowns tipped lingually - roots tipped laterally






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






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






21. Retrognathic profile






22. #7 - 26 - 27






23. Vertical






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






25. Maxillary incisors are are lingual to mandibular incisors






26. Occlusal guard =






27. Horizontal distance of anterior teeth in crossbite






28. 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






29. Horizontal






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






31. Relationship of the arches bone to bone;






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






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






34. Mandibular molars and maxillary molars are even






35. Both sides






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






37. Maxillary - Mandibular - Facial






38. Starts around the mesial of the 1st molar






39. Anterior; no horizontal overlap






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






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






42. Mandibular molars more distal than maxillary molars






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






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






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






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






47. II (mal)occlusion






48. Congenitally missing teeth - Impacted teeth & size and shape of muscle and bone






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






50. 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
