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. Measurement of horizontal overlap w/ probe






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






3. Tooth extracted






4. Mesially - Labially






5. Mandible moves to the right or left






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






7. Horizontal






8. Introduced the concept of codestruction






9. Starts around the mesial of the 1st molar






10. Mesognathic profile






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






12. 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






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






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






15. Later






16. 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






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






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






19. Cervical 3rd






20. Incisal 3rd






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






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






23. Primary teeth set ___________________ for permanent






24. Usually indicative of moderate to sever perio and secondary occ trauma






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






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






27. Retrognathic profile






28. Functional occlusion






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






30. Tongue thrusting; thumb sucking - pacifiers






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






32. When the jaws are closed - the buccal cusps of the mandibular posterior teeth are interlocked between the buccal & lingual cusps of the maxillary teeth






33. Habitual - acquired - convenience - intercuspal & static






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






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






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






37. When no teeth are contacting on this side






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






39. Maximum touching of max and mand






40. Excessive occ force with adequate bone support =






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






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






43. Difference between primary and secondary occ trauma






44. Maxillary overlap mandibular; whole arch






45. Middle 3rd






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






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






48. Selective grinding should always be completed after ______ has been controlled






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






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