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. Relationship of the teeth in opposite arches; static position






2. Vertical






3. Maximum interlocking of cusp






4. Class III (mal)occlusion of permanent teeth






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






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






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






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






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






10. Maxillary incisors are are lingual to mandibular incisors






11. Symptom free dentition that 'survives' or 'adapts' to a deviated occl






12. 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






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






14. Incisal 3rd






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






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






17. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






18. #10 & #23






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






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






21. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious






22. Excessive occ force with adequate bone support =






23. Spaces between two teeth






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






25. Hereditary - Tongue - Intercuspation of teeth - Alignment of previously erupted teeth affects alignment of successive teeth






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






27. Maxillary - Mandibular - Facial






28. What is not affected by occ trauma






29. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






30. Retrognathic profile; buccal groove of mand 1st molar-distal to mb cusp of max 1st; distal of mand. canine distal to mesial to max caniine - tendency toward class II






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






32. Above occlusal plane






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






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






35. Teeth are misaligned when biting together






36. Maxillary overlap mandibular; whole arch






37. ____ is not a sign of occl trauma






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






39. Anterior; no horizontal overlap






40. Lateral mvmt results in contacct of all posterior teeth






41. 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






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






43. Difference between primary and secondary occ trauma






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






45. #7 - 26 - 27






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






47. Habitual - acquired - convenience - intercuspal & static






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






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






50. 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
