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. Measurement of horizontal overlap w/ probe






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






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






4. Horizontal






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






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






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






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






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






10. Mandibular molars more distal than maxillary molars






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






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






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






14. Class III (mal)occlusion of permanent teeth






15. Lateral mvmt results in contacct of all posterior teeth






16. Tooth positioned more facial






17. Incisal 3rd






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






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






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






21. #7 - 26 - 27






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






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






24. Later






25. Maxillary overlap mandibular; whole arch






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






27. 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






28. Mandibular molars and maxillary molars are even






29. Retrognathic profile -buccal groove of mand. 1st molar-distal to mb cusp of 1st max.molar -distal of mand canine distal to mesial of max canine - tendency towards class II






30. What is not affected by occ trauma






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






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






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






34. Both sides






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






36. 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






37. Spaces between two teeth






38. Tooth positioned more lingual






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






40. Laterally






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






42. Vibrational mvmt of a tooth under occ function






43. 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






44. After periodontal sugery - mobility will ________






45. Mandible moves to the right or left






46. Excessive occ force with adequate bone support =






47. Relationship of the arches bone to bone;






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






49. 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






50. Tongue thrusting; thumb sucking - pacifiers
