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. #10 & #23






2. During a left working movement - the right side is known as the






3. Cervical 3rd






4. Relationship of the arches bone to bone;






5. Tooth positioned more facial






6. Functional occlusion






7. Posterior; no horizontal overlap






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






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






10. The patient is constantly tightening the lower lip against the lower anterior teeth causing the the mandibular teeth to be pushed back into the mouth by this overdeveloped lower lip






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






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






13. Starts around the mesial of the 1st molar






14. Excessive occ force with adequate bone support =






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






16. Difference between primary and secondary occ trauma






17. Spaces between two teeth






18. Above occlusal plane






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






20. Occlusal guard =






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






22. 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






23. 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






24. 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






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






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






27. II (mal)occlusion






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






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






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






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






32. Mandibular molars and maxillary molars are even






33. Below occlusal plane






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






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






36. Mesognathic profile






37. Mandibular molars more distal than maxillary molars






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






39. After periodontal sugery - mobility will ________






40. Incisal 3rd






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






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






43. Laterally






44. Measurement of horizontal overlap w/ probe






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






46. Vibrational mvmt of a tooth under occ function






47. 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






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






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






50. Lateral mvmt results in contacct of all posterior teeth
