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. ____ is not a sign of occl trauma






2. When no teeth are contacting on this side






3. Mandible moves to the right or left






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






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






6. Tongue thrusting; thumb sucking - pacifiers






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






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






9. Slight buccal inclination of crown - lingual inclination of root






10. After periodontal sugery - mobility will ________






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






12. Maxillary - Mandibular - Facial






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






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






15. Incisal 3rd






16. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






17. II (mal)occlusion






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






19. Prognathic profile






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






21. 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






22. Maxillary anterior teeth stick out labially from tongue thrusting






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






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






25. 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






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






27. Growth hormone imbalance that causes the mandible to grow faster than the maxilla(all teeth are in crossbite)






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






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






30. Tongue thrust or thumb sucking can cause






31. Relationship of the arches bone to bone;






32. #10 & #23






33. Abnormal contacts; occlusal habits - and neuroses






34. Both sides






35. What is not affected by occ trauma






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






37. Laterally






38. Anterior; no horizontal overlap






39. Below occlusal plane






40. Starts closer to premolars






41. Retrognathic profile -buccal groove of mand. 1st molar-distal to mb cusp of 1st max.molar -distal of mand canine distal to mesial of max canine - tendency towards class II






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






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






44. Occlusal guard =






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






46. Tooth positioned more lingual






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






48. Cervical 3rd






49. Horizontal distance of anterior teeth in crossbite






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