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






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






3. #10 & #23






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






5. Prognathic profile






6. Difference between primary and secondary occ trauma






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






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






9. Tooth positioned more lingual






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






11. Spaces between two teeth






12. Tooth-tooth contacts; tooth-hard objects contacts; tooth-oral tissues contact






13. Horizontal distance of anterior teeth in crossbite






14. Below occlusal plane






15. Teeth are misaligned when biting together






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






17. Cervical 3rd






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






19. Crowns tipped lingually - roots tipped laterally






20. Vertical overlapping






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






22. Class III (mal)occlusion of permanent teeth






23. Most retruded position of the mandible in relation to the maxilla From which lateral mvmts of the jaw can be made






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






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






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






27. Horizontal






28. Maxillary anterior teeth stick out labially from tongue thrusting






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






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






31. Posterior; no horizontal overlap






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






33. 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






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






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






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






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






38. Mesially - Labially






39. #7 - 26 - 27






40. Tongue thrust or thumb sucking can cause






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






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






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






44. 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






45. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






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






47. Laterally






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






49. When no teeth are contacting on this side






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
