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






2. Tooth extracted






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






4. Above occlusal plane






5. When no teeth are contacting on this side






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






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






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






9. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






10. Teeth that are in func when the mandible moves in lateral or protrusive excursions or mvmts






11. Maximum touching of max and mand






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






13. Overlap of anterior teeth






14. 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






15. Maximum interlocking of cusp






16. Prognathic profile






17. 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






18. Later






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






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






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






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






23. 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






24. Occlusal guard =






25. 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






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






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






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






29. Maxillary - Mandibular - Facial






30. Starts closer to premolars






31. Below occlusal plane






32. Vertical overlapping






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






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






35. Vertical






36. Guidance for protrusive occ should be on the






37. ____ is not a sign of occl trauma






38. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






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






40. Mb cusp of max 1st molar-buccal groove of mand 1st molar






41. What is not affected by occ trauma






42. Mand. facial or lingual to max. - unitlateral or bilateral; incorrect horizontal overlap






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






44. Mandible moves to the right or left






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






46. Starts around the mesial of the 1st molar






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






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






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






50. Posterior; no horizontal overlap
