there are 8 parts of the anatomy of alveolar bone:
- basal bone
- cortical bone
- trabecular bone
- alveolar bone proper
- alveolar crest
- interdental septum
- interradicular septum
the bone BENEATH the alveolar bone
which bone forms the body of the mandible and maxilla?
individual tooth socket is called:
COMPACT bone that LINES EACH ALVEOLUS is:
alveolar bone proper
what it is alveolar bone proper called when you are looking at the alveolar bone proper on a RADIOGRAPH?
the most cervical rim of the bone
the alveolar crest should be ___-___ mm apical to the CEJ
COMPACT bone that makes up the FACIAL and LINGUAL WALLS of the bone
CANCELLOUS BONE that FILLS IN THE SPACE between the COMPACT bone
alex TRABECULAR bone from jeopardy, wearing LACE-LIKE underwear
the BONE that directly surrounds and supports the teeth
alveolar bone is formed from ________
what percentage of alveolar bone is mineralized?
60% what the garbage! is that all!?
which component of the periodontium is broken down first when an infection is present?
alveolar bone, it is only 60% mineralized. poor Al!
alveolar bone has ________ fibers that EMBED into the bone and ANCHOR the teeth
SHARPEY'S to the rescue!
the bone between each TOOTH-seen in PAs
the bone between the ROOTS-seen in PAs
interradicular (root) septum
what are four clinical considerations of the alveolar bone?
- ortho movement
- edentulous patients
- perio disease
- bone grafts
T/F the ortho appliance puts pressure on the tooth
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.
if a tooth is moved too quickly during ortho, it will cause _____ ______
root resorption. Patience is a virtue!
T/F it is faster to move adults teeth and slower to move kids teeth with ortho
FALSE! faster with kids, slower with adults
how come after a few years retainers may not be necessary in some cases?
because the matrix needs time to mineralize
what is the most important consideration when possibly placing braces on a kid?
make sure they will promise to take care of their teeth!
if you don't use it, you lose it, what is it?
alveolar bone needs constant _______ of chewing and speaking, or it will _______
T/F implants are a great option because they maintain stimulation.
you be your bottom dollar they are!
T/F dentures are OKAY at maintaining stimulation
true, bone loss occurs slower
an implant should be encouraged ______ than ______
sooner than later
What type of material is used that bone accepts?
T/F in periodontal disease, it is bacteria that eats the bone
FALSE!!!!!!! Bacteria doesn't think it tastes good
over-response of the immune system that breaks down the bone is:
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
what does the body send out to break down the bone in perio disease?
calculus is _____ and holds bacteria
"bone bait" is used for:
when doing a bone graft, it gives the _________ a place to start secreting ________
when are bone grafts usually performed?
right after an extraction in preparation for an implant
does the surgical placement of an implant hurt?
no ma'am! there are no nerves in the bone, just local anesthetic is needed
