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 more mesial than maxillary molars (most children)






2. Abnormal contacts; occlusal habits - and neuroses






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






4. Tooth positioned more lingual






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






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






7. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






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






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






10. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






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






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






13. Primary teeth set ___________________ for permanent






14. Mandible moves to the right or left






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






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






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






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






19. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






20. Anterior; no horizontal overlap






21. Retrognathic profile






22. Starts closer to premolars






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






24. ____ is not a sign of occl trauma






25. During protrusive occ - ______ is considered undesirable






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






27. Introduced the concept of codestruction






28. Lateral mvmt results in contacct of all posterior teeth






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






30. Curved alignment of the occlusal plane when looking from a lateral view(distal to mesial)






31. Difference between primary and secondary occ trauma






32. Buck teeth are common and are considered






33. 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






34. Teeth are misaligned when biting together






35. Posterior; no horizontal overlap






36. Vibrational mvmt of a tooth under occ function






37. 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






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






39. Class III (mal)occlusion of permanent teeth






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






41. Laterally






42. Overlap of anterior teeth






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






44. Horizontal distance of anterior teeth in crossbite






45. Mesognathic profile






46. Mandibular molars more distal than maxillary molars






47. 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






48. Tongue thrust or thumb sucking can cause






49. Patient forces teeth together in centric occlusion on one side to get a more functional bite and has a crossbite on the other side(the midline of the maxillary anterior teeth does not line up with the midlineof the mandible






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