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. Patients show evidence or signs and syptoms of occ disease






2. 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






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






4. 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






5. Above occlusal plane






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






7. Prognathic profile






8. Associated with performance; all contacts during function of the oral cavity






9. Lateral mvmt results in contacct of all posterior teeth






10. Guidance for protrusive occ should be on the






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






12. Need tooth to tooth contact on both working and non working sides to func effectively






13. Tongue thrust or thumb sucking can cause






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






15. Excessive occ force with adequate bone support =






16. Mandibular molars more distal than maxillary molars






17. Overlap of anterior teeth






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






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






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






21. Tooth positioned more facial






22. Horizontal distance of anterior teeth in crossbite






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






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






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






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






27. Vertical






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






29. Teeth are misaligned when biting together






30. 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






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






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






34. Rotated or twisted; rotated mesial or distal






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






36. 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






37. Posterior; no horizontal overlap






38. Mesognathic profile






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






40. Primary teeth set ___________________ for permanent






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






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






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






44. The permanent molars erupt posterior to the primary teeth and push them all mesially






45. Difference between primary and secondary occ trauma






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






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






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






49. During protrusive occ - ______ is considered undesirable






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