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






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






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






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






5. Maxillary - Mandibular - Facial






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






7. Mandibular molars and maxillary molars are even






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






9. Maximum interlocking of cusp






10. Cervical 3rd






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






12. Below occlusal plane






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






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






15. 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






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






17. Horizontal distance of anterior teeth in crossbite






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






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






20. Tongue thrusting; thumb sucking - pacifiers






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






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






23. Mandibular molars more mesial than maxillary molars (most children)






24. Guidance for protrusive occ should be on the






25. Both sides






26. Most common cause is when the maxilla does not grow in proportion to the mandible






27. II (mal)occlusion






28. Starts around the mesial of the 1st molar






29. Mesially - Labially






30. Laterally






31. Rotated or twisted; rotated mesial or distal






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






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






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






35. Introduced the concept of codestruction






36. Anterior or posterior; bilateral or unitlateral - anterior more common






37. Occlusal guard =






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






39. Maxillary incisors are are lingual to mandibular incisors






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






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






42. When no teeth are contacting on this side






43. 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






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






45. During a left working movement - the right side is known as the






46. The permanent molars erupt posterior to the primary teeth and push them all mesially






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






48. Teeth are misaligned when biting together






49. Spaces between two teeth






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