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. 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






2. Mandibular molars more distal than maxillary molars






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






4. Maximum interlocking of cusp






5. 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






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






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






8. ____ is not a sign of occl trauma






9. Buck teeth are common and are considered






10. Tooth extracted






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






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






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






14. #7 - 26 - 27






15. Vertical






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






17. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






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






19. Spaces between two teeth






20. Mandibular molars and maxillary molars are even






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






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






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






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






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






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






27. Occlusal guard =






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






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






30. Tongue thrust or thumb sucking can cause






31. Rotated or twisted; rotated mesial or distal






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






33. Tooth positioned more facial






34. Relationship of the arches bone to bone;






35. Guidance for protrusive occ should be on the






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






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






38. Horizontal distance of anterior teeth in crossbite






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






40. Retrognathic profile






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






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






43. Prognathic profile; buccal groove of mand. 1st molar-mesial to mb cusp of max. 1st molar; distal of mand. canine mesial to mesial of max canine; tendency toward class III






44. Cervical 3rd






45. Mesognathic profile






46. 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






47. Primary teeth set ___________________ for permanent






48. 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






49. Below occlusal plane






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