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






2. 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






3. Mesially - Labially






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






5. Individual teeth from each arch can be involved in ________________ malocclusion






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






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






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






9. Mandibular molars more distal than maxillary molars






10. Relationship of the teeth in opposite arches; static position






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






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






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






14. Starts closer to premolars






15. Cervical 3rd






16. 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






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






18. Spaces between two teeth






19. Overlap of anterior teeth






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






21. Horizontal distance of anterior teeth in crossbite






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






23. A tooth that occludes with an opposing tooth before full closure is achieved in centric occlusion






24. 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






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






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






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






28. Teeth are misaligned when biting together






29. During protrusive occ - ______ is considered undesirable






30. Maximum interlocking of cusp






31. Widening of the PDL in areas under pressure results due to






32. Maxillary overlap mandibular; whole arch






33. Survival of the dentition despite its deviation from a preconceived hypothetical normal






34. Difference between primary and secondary occ trauma






35. Horizontal






36. Maxillary incisors are are lingual to mandibular incisors






37. 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






38. Below occlusal plane






39. Patients show evidence or signs and syptoms of occ disease






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






41. Relationship of the arches bone to bone;






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






43. Lateral mvmt results in contacct of all posterior teeth






44. Above occlusal plane






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






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






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






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






49. Middle 3rd






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