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. Above occlusal plane






2. Horizontal






3. Posterior; no horizontal overlap






4. The tooth has insufficient bone support and normal chewing and swallowing forces are excessive - causing injury to the attachment appartatus






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






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






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






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






9. Vertical






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






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






12. During protrusive occ - ______ is considered undesirable






13. Relationship of the arches bone to bone;






14. Horizontal distance of anterior teeth in crossbite






15. What is not affected by occ trauma






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






17. Tongue thrusting; thumb sucking - pacifiers






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






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






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






21. Lateral mvmt results in contacct of all posterior teeth






22. 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






23. Anterior; no horizontal overlap






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






25. Buck teeth are common and are considered






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






27. Cervical 3rd






28. When no teeth are contacting on this side






29. Class III (mal)occlusion of permanent teeth






30. Vibrational mvmt of a tooth under occ function






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






32. Prognathic profile






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






34. Teeth are misaligned when biting together






35. Mandible moves to the right or left






36. 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






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






38. Malocclusion cause excessive incisal or occlusal wear(attrition); teeth continue to erupt in order to occlude with teeth in the opposite arch & roots become exposed






39. Crowns tipped lingually - roots tipped laterally






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






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






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






43. 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






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






45. Teeth that are in func when the mandible moves in lateral or protrusive excursions or mvmts






46. Introduced the concept of codestruction






47. Abnormal contacts; occlusal habits - and neuroses






48. Prognathic profile; buccal groove of mand. 1st molar-mesial to mb cusp of max. 1st molar; distal of mand. canine mesial to mesial of max canine; tendency toward class III






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






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