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






2. Maxillary incisors are are lingual to mandibular incisors






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






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






5. Measurement of horizontal overlap w/ probe






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






7. #10 & #23






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






9. Relationship of the arches bone to bone;






10. 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






11. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






12. Mesially - Labially






13. Functional occlusion






14. 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






15. Crowns tipped lingually - roots tipped laterally






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






17. Lateral mvmt results in contacct of all posterior teeth






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






19. 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






20. Starts closer to premolars






21. After periodontal sugery - mobility will ________






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






23. Vertical overlapping






24. Occlusal guard =






25. Middle 3rd






26. Excessive occ force with adequate bone support =






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






29. Aquired centric occlusion - habitual occlusion - convienience occlusion - or intercuspal position






30. Vibrational mvmt of a tooth under occ function






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






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






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






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






35. Starts closer to the posterior of the 1st molar






36. II (mal)occlusion






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






38. Maxillary-between canines and laterals - mandibular-between canines and 1st molars






39. Above occlusal plane






40. Tongue thrusting; thumb sucking - pacifiers






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






42. What is not affected by occ trauma






43. Mandibular molars and maxillary molars are even






44. Maxillary overlap mandibular; whole arch






45. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






46. Reshaping of the occ or incisal surfaces of teeth to create contacts btwn upper and lower dentition






47. Both sides






48. 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






49. Overlap of anterior teeth






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