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






2. Excessive occ force with adequate bone support =






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






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






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






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






7. Posterior; no horizontal overlap






8. Introduced the concept of codestruction






9. Relationship of the arches bone to bone;






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






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






12. Abnormal contacts; occlusal habits - and neuroses






13. Maxillary overlap mandibular; whole arch






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






15. Selective grinding should always be completed after ______ has been controlled






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






17. 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






18. Retrognathic profile -buccal groove of mand. 1st molar-distal to mb cusp of 1st max.molar -distal of mand canine distal to mesial of max canine - tendency towards class II






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






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






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






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






23. Later






24. Mesognathic profile






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






26. Mandible moves to the right or left






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






28. Functional occlusion






29. Starts around the mesial of the 1st molar






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






31. Below occlusal plane






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






33. After periodontal sugery - mobility will ________






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






35. ____ is not a sign of occl trauma






36. Buck teeth are common and are considered






37. #7 - 26 - 27






38. Prognathic profile






39. Maxillary anterior teeth stick out labially from tongue thrusting






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






41. A tooth that occludes with an opposing tooth before full closure is achieved in centric occlusion






42. Rotated or twisted; rotated mesial or distal






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






44. Habitual - acquired - convenience - intercuspal & static






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






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






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






48. Anterior teeth do not occlude - or remain open - while posterior teeth may have a normal occlusion






49. Mandibular molars and maxillary molars are even






50. Teeth are misaligned when biting together
