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. #10 & #23






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






3. Primary teeth set ___________________ for permanent






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






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






6. Mesognathic profile






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






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






9. Tooth extracted






10. Class III (mal)occlusion of permanent teeth






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






12. What is not affected by occ trauma






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






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






15. Retrognathic profile






16. After periodontal sugery - mobility will ________






17. 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






18. Anterior; no horizontal overlap






19. Introduced the concept of codestruction






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






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






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






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






24. Rotated or twisted; rotated mesial or distal






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






26. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






27. 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






28. Mand. facial or lingual to max. - unitlateral or bilateral; incorrect horizontal overlap






29. Buck teeth are common and are considered






30. Congenitally missing teeth - Impacted teeth & size and shape of muscle and bone






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






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






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






34. Posterior; no horizontal overlap






35. Tongue thrust or thumb sucking can cause






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






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






38. Both sides






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






40. Spaces between two teeth






41. The permanent molars erupt posterior to the primary teeth and push them all mesially






42. Crowns tipped lingually - roots tipped laterally






43. Mandibular molars and maxillary molars are even






44. Tongue thrusting; thumb sucking - pacifiers






45. Prognathic profile






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






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






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






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






50. Excessive occ force with adequate bone support =
