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. Posterior; no horizontal overlap






2. Both sides






3. Prognathic profile






4. ____ is not a sign of occl trauma






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






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






7. II (mal)occlusion






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






9. Crowns tipped lingually - roots tipped laterally






10. Maximum touching of max and mand






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






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






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






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






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






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






17. Measurement of horizontal overlap w/ probe






18. Starts closer to premolars






19. 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






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






21. 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






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






23. 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






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






25. Primary teeth set ___________________ for permanent






26. Teeth are misaligned when biting together






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






28. Tooth positioned more lingual






29. Lateral mvmt results in contacct of all posterior teeth






30. Anterior; no horizontal overlap






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






32. Laterally






33. Horizontal distance of anterior teeth in crossbite






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






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






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






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






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






39. Mesognathic profile






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






41. Mandibular molars and maxillary molars are even






42. Permits healing of the attachment apparatus by holding a tooth in a totally fixed position; allows the PDL to become narrower and the mobility to be reduced






43. Usually indicative of moderate to sever perio and secondary occ trauma






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






45. When no teeth are contacting on this side






46. Middle 3rd






47. During protrusive occ - ______ is considered undesirable






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






49. 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






50. Retrognathic profile
