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. #7 - 26 - 27






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






3. Tooth positioned more lingual






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






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






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






7. Starts around the mesial of the 1st molar






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






9. Tongue thrust or thumb sucking can cause






10. Mand. facial or lingual to max. - unitlateral or bilateral; incorrect horizontal overlap






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






12. Habitual - acquired - convenience - intercuspal & static






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






14. Mandibular molars and maxillary molars are even






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






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






17. Functional occlusion






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






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






20. Maxillary - Mandibular - Facial






21. Spaces between two teeth






22. Mandibular molars more distal than maxillary molars






23. Rotated or twisted; rotated mesial or distal






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






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






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






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






28. Guidance for protrusive occ should be on the






29. 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






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






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






32. Later






33. After periodontal sugery - mobility will ________






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






35. Above occlusal plane






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






37. 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






38. Occlusal guard =






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






40. Horizontal






41. Mandible moves to the right or left






42. Cervical 3rd






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






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






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






46. 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






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






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






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






50. Lateral mvmt results in contacct of all posterior teeth
