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. Mandibular molars and maxillary molars are even






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






3. Starts around the mesial of the 1st molar






4. Above occlusal plane






5. Horizontal distance of anterior teeth in crossbite






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






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






8. Buck teeth are common and are considered






9. Habitual - acquired - convenience - intercuspal & static






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






11. Introduced the concept of codestruction






12. Retrognathic profile






13. Maxillary incisors are are lingual to mandibular incisors






14. Later






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






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






17. Spaces between two teeth






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






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






20. 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






21. Anterior crossbite; max/mand incisors-edge to edge occlusion; crowded mand. incisors






22. Measurement of horizontal overlap w/ probe






23. 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






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






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






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






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






28. Occlusal guard =






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






30. Mesognathic profile






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






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






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






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






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






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






37. #7 - 26 - 27






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






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






40. Laterally






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






42. Mandibular molars more distal than maxillary molars






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






44. Maxillary - Mandibular - Facial






45. Tongue thrusting; thumb sucking - pacifiers






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






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






48. Incisal 3rd






49. Lateral mvmt results in contacct of all posterior teeth






50. Functional occlusion
