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






2. Crowns tipped lingually - roots tipped laterally






3. Measurement of horizontal overlap w/ probe






4. Tooth positioned more lingual






5. During protrusive occ - ______ is considered undesirable






6. 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






7. Spaces between two teeth






8. Starts closer to premolars






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






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






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






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






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






14. Anterior; no horizontal overlap






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






16. II (mal)occlusion






17. Occlusal guard =






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






19. Mandibular molars more distal than maxillary molars






20. Guidance for protrusive occ should be on the






21. Maxillary incisors are are lingual to mandibular incisors






22. Lateral mvmt results in contacct of all posterior teeth






23. Class III (mal)occlusion of permanent teeth






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






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






26. Both sides






27. 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






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






29. Habitual - acquired - convenience - intercuspal & static






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






31. 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






32. Introduced the concept of codestruction






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






34. Laterally






35. ____ is not a sign of occl trauma






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






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






38. Maximum touching of max and mand






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






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






41. Curved alignment of the occlusal plane when looking from a posterior view(right to left)






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






43. 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






44. 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






45. Tooth extracted






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






47. Maxillary anterior teeth stick out labially from tongue thrusting






48. Maximum interlocking of cusp






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






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