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






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






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






4. Later






5. Mandibular molars more distal than maxillary molars






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






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






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






9. Tongue thrusting; thumb sucking - pacifiers






10. Tongue thrust or thumb sucking can cause






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






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






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






14. Vibrational mvmt of a tooth under occ function






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






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






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






18. Maxillary anterior teeth stick out labially from tongue thrusting






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






20. Maximum interlocking of cusp






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






22. Maximum touching of max and mand






23. Spaces between two teeth






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






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






26. Starts around the mesial of the 1st molar






27. ____ is not a sign of occl trauma






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






29. Overlap of anterior teeth






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






31. Habitual - acquired - convenience - intercuspal & static






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






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






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






35. Below occlusal plane






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






37. Maxillary incisors are are lingual to mandibular incisors






38. Maxillary overlap mandibular; whole arch






39. 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






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






41. Curve of the occlusal plane; from anterior to posterior - increases with age






42. Tooth positioned more facial






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






44. Tooth-tooth contacts; tooth-hard objects contacts; tooth-oral tissues contact






45. Cervical 3rd






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






47. 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






48. Introduced the concept of codestruction






49. 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






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