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






2. When no teeth are contacting on this side






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






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






5. 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






6. Contact between maxillary incisors does not line up with contact of mandibular incisors






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






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






9. 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






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






11. Starts closer to premolars






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






13. 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






14. Spaces between two teeth






15. Functional occlusion






16. Tooth extracted






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






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






19. Laterally






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






21. Mandibular molars and maxillary molars are even






22. Maximum touching of max and mand






23. Mesially - Labially






24. Vertical overlapping






25. Lateral mvmt results in contacct of all posterior teeth






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






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






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






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






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






31. Above occlusal plane






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






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






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






35. Introduced the concept of codestruction






36. 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






37. Mandible moves to the right or left






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






39. During protrusive occ - ______ is considered undesirable






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






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






42. II (mal)occlusion






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






44. If the mandible moves to the left - the mvmt is known as a left working movement






45. What is not affected by occ trauma






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






47. 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






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






49. Mesognathic profile






50. Retrognathic profile; buccal groove of mand 1st molar-distal to mb cusp of max 1st; distal of mand. canine distal to mesial to max caniine - tendency toward class II
