  1. there are 8 parts of the anatomy of alveolar bone:
    • basal bone
    • cortical bone
    • trabecular bone
    • alveolar bone proper
    • alveolus
    • alveolar crest
    • interdental septum
    • interradicular septum
  2. the bone BENEATH the alveolar bone
    basal bone
  3. which bone forms the body of the mandible and maxilla?
    basal bone
  4. individual tooth socket is called:
    alveolus
  5. COMPACT bone that LINES EACH ALVEOLUS is:
    alveolar bone proper
  6. what it is alveolar bone proper called when you are looking at the alveolar bone proper on a RADIOGRAPH?
    lamina dura
  7. the most cervical rim of the bone
    alveolar crest
  8. the alveolar crest should be ___-___ mm apical to the CEJ
    1-2
  9. COMPACT bone that makes up the FACIAL and LINGUAL WALLS of the bone
    cortical bone
  10. CANCELLOUS BONE that FILLS IN THE SPACE between the COMPACT bone
    alex TRABECULAR bone from jeopardy, wearing LACE-LIKE underwear
  11. the BONE that directly surrounds and supports the teeth
    alveolar bone
  12. alveolar bone is formed from ________
    MESODERM
  13. what percentage of alveolar bone is mineralized?
    60% what the garbage! is that all!?
  14. which component of the periodontium is broken down first when an infection is present?
    alveolar bone, it is only 60% mineralized. poor Al!
  15. alveolar bone has ________ fibers that EMBED into the bone and ANCHOR the teeth
    SHARPEY'S to the rescue!
  16. the bone between each TOOTH-seen in PAs
    interdental septum
  17. the bone between the ROOTS-seen in PAs
    interradicular (root) septum
  18. what are four clinical considerations of the alveolar bone?
    • ortho movement
    • edentulous patients
    • perio disease
    • bone grafts
  19. T/F the ortho appliance puts pressure on the tooth
    true!
  20. during ortho movement, the tooth moves through the _____ while ________ on the compressed side break down the bone and ________ rebuild the bone on the opposite side.
    • bone
    • osetoCLASTS
    • osteoBLASTS
  21. if a tooth is moved too quickly during ortho, it will cause _____ ______
    root resorption. Patience is a virtue!
  22. T/F it is faster to move adults teeth and slower to move kids teeth with ortho
    FALSE! faster with kids, slower with adults
  23. how come after a few years retainers may not be necessary in some cases?
    because the matrix needs time to mineralize
  24. what is the most important consideration when possibly placing braces on a kid?
    make sure they will promise to take care of their teeth!
  25. if you don't use it, you lose it, what is it?
    alveolar bone!
  26. alveolar bone needs constant _______ of chewing and speaking, or it will _______
    • stimulation
    • resorb
  27. T/F implants are a great option because they maintain stimulation.
    you be your bottom dollar they are!
  28. T/F dentures are OKAY at maintaining stimulation
    true, bone loss occurs slower
  29. an implant should be encouraged ______ than ______
    sooner than later
  30. What type of material is used that bone accepts?
    titanium
  31. T/F in periodontal disease, it is bacteria that eats the bone
    FALSE!!!!!!! Bacteria doesn't think it tastes good
  32. over-response of the immune system that breaks down the bone is:
    periodontal disease
  33. your body knows that infections can go systemic, so it would rather get rid of the tooth than die of infection
    thats all i wanted to say about that
  34. what does the body send out to break down the bone in perio disease?
    osteoCLASTS
  35. calculus is _____ and holds bacteria
    porus
  36. "bone bait" is used for:
    bone grafts
  37. when doing a bone graft, it gives the _________ a place to start secreting ________
    • osteoBLASTS
    • OSTEIOD
  38. when are bone grafts usually performed?
    right after an extraction in preparation for an implant
  39. does the surgical placement of an implant hurt?
    no ma'am! there are no nerves in the bone, just local anesthetic is needed
