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. Vibrational mvmt of a tooth under occ function






2. Tooth positioned more facial






3. 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






4. Occlusal guard =






5. Incisal 3rd






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






7. Habitual - acquired - convenience - intercuspal & static






8. Primary teeth set ___________________ for permanent






9. Buck teeth are common and are considered






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






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






12. Maxillary overlap mandibular; whole arch






13. Mobility - migration - pain - premature contact - widening of PDL - parafuntional habits - TMJ problems - all result in _________






14. Introduced the concept of codestruction






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






16. Relationship of the arches bone to bone;






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






18. ____ is not a sign of occl trauma






19. Mandible moves to the right or left






20. Malocclusion cause excessive incisal or occlusal wear(attrition); teeth continue to erupt in order to occlude with teeth in the opposite arch & roots become exposed






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






22. The relationship of the teeth in the mandibular arch to those in the maxillary arch as they are brought together






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






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






25. High restoration - parafunctional habits - malpositioned tooth - periapical abcess - physical 'blow' - removable partial - ortho mvmt






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






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






28. 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






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






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






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






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






33. Vertical






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






35. #10 & #23






36. #7 - 26 - 27






37. Mandibular molars more distal than maxillary molars






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






39. During protrusive occ - ______ is considered undesirable






40. Vertical overlapping






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






42. Starts closer to premolars






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






44. II (mal)occlusion






45. Malposition - crowded anterior teeth - protruded or retruded max incisors - anterior/posterior crossbite - mesial drift






46. Maximum touching of max and mand






47. Crowns tipped lingually - roots tipped laterally






48. Mesially - Labially






49. Both sides






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