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. Horizontal






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






3. Functional occlusion






4. Most retruded position of the mandible in relation to the maxilla From which lateral mvmts of the jaw can be made






5. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






6. Class III (mal)occlusion of permanent teeth






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






8. Below occlusal plane






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






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






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






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






13. Tooth extracted






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






15. Vertical






16. When no teeth are contacting on this side






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






18. Maxillary - Mandibular - Facial






19. Maxillary incisors are are lingual to mandibular incisors






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






21. Relationship of the arches bone to bone;






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






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






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






25. Tooth positioned more facial






26. 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






27. Middle 3rd






28. II (mal)occlusion






29. If the mandible moves to the left - the mvmt is known as a left working movement






30. Lateral mvmt results in contacct of all posterior teeth






31. Primary teeth set ___________________ for permanent






32. Prognathic profile






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






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






35. Difference between primary and secondary occ trauma






36. Mesognathic profile






37. Vertical overlapping






38. Teeth are misaligned when biting together






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






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






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






42. After periodontal sugery - mobility will ________






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






44. 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






45. Rotated or twisted; rotated mesial or distal






46. Maxillary overlap mandibular; whole arch






47. Mandibular molars and maxillary molars are even






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






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






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