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. Curve of the occlusal plane; from anterior to posterior - increases with age






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






3. 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






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






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






6. #10 & #23






7. Tongue thrusting; thumb sucking - pacifiers






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






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






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






11. Tooth positioned more lingual






12. Class III (mal)occlusion of permanent teeth






13. Difference between primary and secondary occ trauma






14. Introduced the concept of codestruction






15. 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






16. Mesially - Labially






17. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






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






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






20. Both sides






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






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






23. Measurement of horizontal overlap w/ probe






24. Curve spee & wilson - 3-d - not proven






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






26. Maxillary overlap mandibular; whole arch






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






28. A tooth that occludes with an opposing tooth before full closure is achieved in centric occlusion






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






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






31. Mandibular molars more distal than maxillary molars






32. Starts closer to premolars






33. Buck teeth are common and are considered






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






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






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






37. Anterior; no horizontal overlap






38. Cervical 3rd






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






40. Later






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






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






43. Occlusal guard =






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






45. When no teeth are contacting on this side






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






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






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






49. Maximum interlocking of cusp






50. 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
