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. Vertical






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






3. Starts around the mesial of the 1st molar






4. Maxillary - Mandibular - Facial






5. Horizontal






6. Abnormal contacts; occlusal habits - and neuroses






7. Prognathic profile






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






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






10. During selective grinding - occlusion should be adjusted In what four relationships






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






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






13. Later






14. After periodontal sugery - mobility will ________






15. Habitual - acquired - convenience - intercuspal & static






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






17. Maximum touching of max and mand






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






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






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






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






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






23. Anterior; no horizontal overlap






24. Tooth extracted






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






26. Maxillary overlap mandibular; whole arch






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






28. Horizontal distance of anterior teeth in crossbite






29. 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






30. Lateral mvmt results in contact btwn the max and mand canines






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






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






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






34. Primary teeth set ___________________ for permanent






35. Maxillary incisors are are lingual to mandibular incisors






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






37. Incisal 3rd






38. 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






39. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






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






41. Functional occlusion






42. Mesognathic profile






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






44. Posterior; no horizontal overlap






45. Both sides






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






47. The patient is constantly tightening the lower lip against the lower anterior teeth causing the the mandibular teeth to be pushed back into the mouth by this overdeveloped lower lip






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






49. Tongue thrusting; thumb sucking - pacifiers






50. Excessive occ force with adequate bone support =
