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. Laterally






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






3. Introduced the concept of codestruction






4. Occlusal guard =






5. Tongue thrusting; thumb sucking - pacifiers






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






7. 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






8. Above occlusal plane






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






10. Maximum interlocking of cusp






11. Difference between primary and secondary occ trauma






12. Maxillary anterior teeth stick out labially from tongue thrusting






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






14. Overlap of anterior teeth






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






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






17. Prognathic profile






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






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






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






21. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious






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






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






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






25. Class III (mal)occlusion of permanent teeth






26. Guidance for protrusive occ should be on the






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






28. Teeth are misaligned when biting together






29. ____ is not a sign of occl trauma






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






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






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






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






34. Functional occlusion






35. Buck teeth are common and are considered






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






37. Maxillary incisors are are lingual to mandibular incisors






38. Vibrational mvmt of a tooth under occ function






39. Maximum touching of max and mand






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






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






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






43. Reshaping of the occ or incisal surfaces of teeth to create contacts btwn upper and lower dentition






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






45. Anterior crossbite; max/mand incisors-edge to edge occlusion; crowded mand. incisors






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






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






48. Horizontal






49. Tooth extracted






50. During protrusive occ - ______ is considered undesirable
