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. Below occlusal plane






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






3. 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






4. 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






5. After periodontal sugery - mobility will ________






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






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






8. Tongue thrusting; thumb sucking - pacifiers






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






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






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






12. 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






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






14. Horizontal






15. Relationship of the arches bone to bone;






16. Retrognathic profile






17. Cervical 3rd






18. Symptom free dentition that 'survives' or 'adapts' to a deviated occl






19. Maxillary overlap mandibular; whole arch






20. Incisal 3rd






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






22. Laterally






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






24. Both sides






25. Maximum interlocking of cusp






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






27. Posterior; no horizontal overlap






28. Starts around the mesial of the 1st molar






29. Maxillary anterior teeth stick out labially from tongue thrusting






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






31. What is not affected by occ trauma






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






33. Radiographically - the PDL space is wider at the coronal third of the root






34. Teeth are misaligned when biting together






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






36. Tongue thrust or thumb sucking can cause






37. During protrusive occ - ______ is considered undesirable






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






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






40. Introduced the concept of codestruction






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






42. Measurement of horizontal overlap w/ probe






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






44. Maximum touching of max and mand






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






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






47. Mesognathic profile






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






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






50. Guidance for protrusive occ should be on the
