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. Buck teeth are common and are considered






2. Lateral mvmt results in contacct of all posterior teeth






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






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






5. Overlap of anterior teeth






6. Slight buccal inclination of crown - lingual inclination of root






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






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






9. Prognathic profile






10. Laterally






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






12. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






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






14. Starts around the mesial of the 1st molar






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






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






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






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






19. Tooth positioned more facial






20. 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






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






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






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






24. 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






25. Spaces between two teeth






26. Abnormal contacts; occlusal habits - and neuroses






27. Maxillary overlap mandibular; whole arch






28. Maxillary incisors are are lingual to mandibular incisors






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






30. 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






31. Relationship of the teeth in which the incisal ridges of the maxillary anterior teeth extend below the incisal edges of the mandibular anterior teeth when the teeth are placed in a centric occlusal relationship






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






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






34. Maximal intercuspation or contact of the max and mand teeth






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






36. II (mal)occlusion






37. Curve spee & wilson - 3-d - not proven






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






39. Radiographically - the PDL space is wider at the coronal third of the root






40. 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






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






42. Class III (mal)occlusion of permanent teeth






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






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






45. Functional occlusion






46. Middle 3rd






47. Measurement of horizontal overlap w/ probe






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






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






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