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. Mesially - Labially






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






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






4. Introduced the concept of codestruction






5. Functional occlusion






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






7. Spaces between two teeth






8. Rotated or twisted; rotated mesial or distal






9. Above occlusal plane






10. Anterior or posterior; bilateral or unitlateral - anterior more common






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






12. Vertical






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






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






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






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






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






18. During protrusive occ - ______ is considered undesirable






19. Starts around the mesial of the 1st molar






20. #10 & #23






21. 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






22. #7 - 26 - 27






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






24. Tongue thrusting; thumb sucking - pacifiers






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






26. 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






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






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






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






30. Transverse occlusal curvature; posterior teeth; medio-lateral postion (r-l)






31. Vertical overlapping






32. Mandibular molars more distal than maxillary molars






33. ____ is not a sign of occl trauma






34. Lateral mvmt results in contacct of all posterior teeth






35. Can affect the TMJ - muscles of mastication - pulp and integrity of restorations






36. Anterior; no horizontal overlap






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






38. Incisal 3rd






39. Tooth positioned more facial






40. Horizontal distance of anterior teeth in crossbite






41. Crowns tipped lingually - roots tipped laterally






42. Tongue thrust or thumb sucking can cause






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






44. Later






45. Both sides






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






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






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






49. Measurement of horizontal overlap w/ probe






50. Mandibular molars and maxillary molars are even
