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. 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






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






3. Tooth positioned more lingual






4. Crowns tipped lingually - roots tipped laterally






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






6. Teeth are misaligned when biting together






7. Muscles that work the jaw; may become sore due to occ trauma






8. Relationship of the arches bone to bone;






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






10. 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






11. #7 - 26 - 27






12. Maxillary overlap mandibular; whole arch






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






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






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






16. Mesognathic profile






17. Malposition - crowded anterior teeth - protruded or retruded max incisors - anterior/posterior crossbite - mesial drift






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






19. Tooth extracted






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






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






22. Retrognathic profile






23. Lateral mvmt results in contacct of all posterior teeth






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






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






26. Horizontal distance of anterior teeth in crossbite






27. Maximum touching of max and mand






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






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






30. Maxillary - Mandibular - Facial






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






32. 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






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






34. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






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






36. Functional occlusion






37. Vertical






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






39. Laterally






40. 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






41. Measurement of horizontal overlap w/ probe






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






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






44. Occlusal guard =






45. Mandibular molars more distal than maxillary molars






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






47. Mesially - Labially






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






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






50. Starts closer to premolars
