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. Need tooth to tooth contact on both working and non working sides to func effectively






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






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






4. Maxillary incisors are are lingual to mandibular incisors






5. 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






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






7. Abnormal contacts; occlusal habits - and neuroses






8. Mb cusp of max 1st molar-buccal groove of mand 1st molar






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






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






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






12. Position of the mandible relative to the maxilla during swallowing and other times when the jaw muscles contract






13. Incisal 3rd






14. 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






15. Symptom free dentition that 'survives' or 'adapts' to a deviated occl






16. Vertical






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






18. Prognathic profile






19. Mesially - Labially






20. Excessive occ force with adequate bone support =






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






22. Below occlusal plane






23. Anterior; no horizontal overlap






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






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






26. Retrognathic profile






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






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. Primary teeth set ___________________ for permanent






30. Overlap of anterior teeth






31. Vertical overlapping






32. Maxillary - Mandibular - Facial






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






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






35. Habitual - acquired - convenience - intercuspal & static






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






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






38. Anterior crossbite; max/mand incisors-edge to edge occlusion; crowded mand. incisors






39. Maximum interlocking of cusp






40. Lateral mvmt results in contacct of all posterior teeth






41. Normal contacts between max. and mand. teeth; momentary contacts






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






43. During protrusive occ - ______ is considered undesirable






44. 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






45. Spaces between two teeth






46. 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






47. #10 & #23






48. Occlusal guard =






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






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