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. Mandibular molars more distal than maxillary molars






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






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






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






5. Vertical overlapping






6. Posterior; no horizontal overlap






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






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






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






10. Maxillary overlap mandibular; whole arch






11. #10 & #23






12. Tooth extracted






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






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






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






17. Mandibular molars and maxillary molars are even






18. Teeth are misaligned when biting together






19. A continuation of the spee of to extend through the condyle






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






21. 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






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






23. Guidance for protrusive occ should be on the






24. Overlap of anterior teeth






25. Introduced the concept of codestruction






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






27. Tooth positioned more facial






28. Tongue thrust or thumb sucking can cause






29. II (mal)occlusion






30. Tooth positioned more lingual






31. Both sides






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






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. When no teeth are contacting on this side






35. Horizontal






36. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






37. Selective grinding should always be completed after ______ has been controlled






38. Anterior crossbite; max/mand incisors-edge to edge occlusion; crowded mand. incisors






39. Spaces between two teeth






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






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






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






43. 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






44. 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






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






46. Primary teeth set ___________________ for permanent






47. Habitual - acquired - convenience - intercuspal & static






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






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






50. Retrognathic profile
