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






2. Occlusal guard =






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






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






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






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






7. Maxillary incisors are are lingual to mandibular incisors






8. 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






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






10. 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






11. Maxillary - Mandibular - Facial






12. Prognathic profile






13. Mandibular molars and maxillary molars are even






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






15. Tooth positioned more facial






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






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






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






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






20. 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






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






22. 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






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






24. Mesially - Labially






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






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






27. When no teeth are contacting on this side






28. Excessive occ force with adequate bone support =






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






30. After periodontal sugery - mobility will ________






31. Teeth are misaligned when biting together






32. Selective grinding should always be completed after ______ has been controlled






33. Horizontal






34. Anterior; no horizontal overlap






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






36. Widening of the PDL in areas under pressure results due to






37. 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






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






39. Both sides






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






41. Retrognathic profile






42. Lateral mvmt results in contacct of all posterior teeth






43. Because the permanent premolars are narrower than the primary molars that they replace - this is what happens when the premolars erupt






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






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






46. Tongue thrusting; thumb sucking - pacifiers






47. Curved alignment of the occlusal plane when looking from a posterior view(right to left)






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






49. 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






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