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. Tongue thrusting; thumb sucking - pacifiers






2. Injury to the attachment apparatus (bone - PDL - and cementum) as a consequence of normal or excessive occ forces






3. Posterior; no horizontal overlap






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






5. Crowns tipped lingually - roots tipped laterally






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






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






8. Excessive occ force with adequate bone support =






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






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






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






12. Maxillary incisors are are lingual to mandibular incisors






13. Tooth extracted






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






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






16. #7 - 26 - 27






17. Relationship of the teeth in opposite arches; static position






18. Cusps of maxillary teeth directly over cusps of mandibular teeth






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






20. Functional occlusion






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






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






23. Occlusal guard =






24. Maxillary overlap mandibular; whole arch






25. Anterior; no horizontal overlap






26. 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






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






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






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






30. Mandibular molars more distal than maxillary molars






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






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






33. Primary teeth set ___________________ for permanent






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






35. 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






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






37. Above occlusal plane






38. 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






39. Buck teeth are common and are considered






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






41. Introduced the concept of codestruction






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






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






44. Difference between primary and secondary occ trauma






45. Relationship of the arches bone to bone;






46. Maximum interlocking of cusp






47. Tooth positioned more facial






48. Later






49. Lateral mvmt results in contacct of all posterior teeth






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