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. Rotated or twisted; rotated mesial or distal






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






3. What is not affected by occ trauma






4. Functional occlusion






5. Occlusal guard =






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






7. When no teeth are contacting on this side






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






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






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






11. During protrusive occ - ______ is considered undesirable






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






13. Tooth positioned more facial






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






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






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






17. Mandibular molars more distal than maxillary molars






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






19. Widening of the PDL in areas under pressure results due to






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






21. Maxillary - Mandibular - Facial






22. Incisal 3rd






23. Tongue thrusting; thumb sucking - pacifiers






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






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






26. Excessive occ force with adequate bone support =






27. Horizontal






28. II (mal)occlusion






29. Prognathic profile






30. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






31. Relationship of the arches bone to bone;






32. 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






33. 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






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






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






36. Vibrational mvmt of a tooth under occ function






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






38. #7 - 26 - 27






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






40. When the jaws are closed - the buccal cusps of the mandibular posterior teeth are interlocked between the buccal & lingual cusps of the maxillary teeth






41. Most retruded position of the mandible in relation to the maxilla From which lateral mvmts of the jaw can be made






42. Maximal intercuspation or contact of the max and mand teeth






43. Laterally






44. Buck teeth are common and are considered






45. After periodontal sugery - mobility will ________






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






47. Difference between primary and secondary occ trauma






48. During a left working movement - the right side is known as the






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






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