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. Overlap of anterior teeth






2. Mandibular molars more distal than maxillary molars






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






4. Vertical






5. Tooth positioned more lingual






6. Mvmt of the mandible in a direction anterior to centric occ






7. Abnormal contacts; occlusal habits - and neuroses






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






9. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation






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






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






12. 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






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






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






15. Primary teeth set ___________________ for permanent






16. Curve of the occlusal plane; from anterior to posterior - increases with age






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






18. Incisal 3rd






19. During protrusive occ - ______ is considered undesirable






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






21. Relationship of the arches bone to bone;






22. Spaces between two teeth






23. Maximum interlocking of cusp






24. #7 - 26 - 27






25. Maxillary overlap mandibular; whole arch






26. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






27. Horizontal






28. 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






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






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






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






32. Mesially - Labially






33. Maxillary - Mandibular - Facial






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






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






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






37. Above occlusal plane






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






39. Mandibular molars and maxillary molars are even






40. Cervical 3rd






41. Curved alignment of the occlusal plane when looking from a lateral view(distal to mesial)






42. When no teeth are contacting on this side






43. 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






44. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






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






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






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






48. Below occlusal plane






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






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