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






2. Lateral mvmt results in contacct of all posterior teeth






3. Maximum interlocking of cusp






4. Horizontal






5. Occlusal guard =






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






7. Spaces between two teeth






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






9. ____ is not a sign of occl trauma






10. When no teeth are contacting on this side






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






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






13. Mesognathic profile






14. Tooth positioned more lingual






15. Buck teeth are common and are considered






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






17. 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






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






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






20. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






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






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






23. 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






24. 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






25. Excessive occ force with adequate bone support =






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






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






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






29. Below occlusal plane






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






31. Vibrational mvmt of a tooth under occ function






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






33. 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






34. 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






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






36. Posterior; no horizontal overlap






37. Primary teeth set ___________________ for permanent






38. Overlap of anterior teeth






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






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






41. 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






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






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






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






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






46. Middle 3rd






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






48. Teeth are misaligned when biting together






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






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