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. Maxillary incisors are are lingual to mandibular incisors






2. Starts closer to premolars






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






4. Usually indicative of moderate to sever perio and secondary occ trauma






5. 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






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






7. Difference between primary and secondary occ trauma






8. Both sides






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






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






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






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






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






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






15. Prognathic profile






16. Retrognathic profile






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






18. Functional occlusion






19. Lateral mvmt results in contacct of all posterior teeth






20. Teeth that are in func when the mandible moves in lateral or protrusive excursions or mvmts






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






22. Middle 3rd






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






24. After periodontal sugery - mobility will ________






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






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






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






28. Teeth are misaligned when biting together






29. Starts closer to the posterior of the 1st molar






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






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






32. II (mal)occlusion






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






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






35. What is not affected by occ trauma






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






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






38. Posterior; no horizontal overlap






39. A continuation of the spee of to extend through the condyle






40. Horizontal






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






42. The permanent molars erupt posterior to the primary teeth and push them all mesially






43. Maxillary anterior teeth stick out labially from tongue thrusting






44. Mesially - Labially






45. Cervical 3rd






46. Starts around the mesial of the 1st molar






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






48. Guidance for protrusive occ should be on the






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






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