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






2. Teeth are misaligned when biting together






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






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






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






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






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






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






9. Vibrational mvmt of a tooth under occ function






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






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






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






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






14. Maxillary anterior teeth stick out labially from tongue thrusting






15. During protrusive occ - ______ is considered undesirable






16. 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






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






18. Position of the mandible relative to the maxilla during swallowing and other times when the jaw muscles contract






19. Above occlusal plane






20. Mandible moves to the right or left






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






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






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






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






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






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






27. Tooth extracted






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






29. ____ is not a sign of occl trauma






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






31. Mandibular molars and maxillary molars are even






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






33. Habitual - acquired - convenience - intercuspal & static






34. Middle 3rd






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






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






37. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






38. Mandibular molars more mesial than maxillary molars (most children)






39. 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






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






41. Guidance for protrusive occ should be on the






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






43. 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






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






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






46. Anterior teeth do not occlude - or remain open - while posterior teeth may have a normal occlusion






47. Relationship of the arches bone to bone;






48. Difference between primary and secondary occ trauma






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






50. When no teeth are contacting on this side
