|
|
|
charac. of alveolar crest
|
The coronal border of alveolar process; about 1.5mm below the DEJ
|
|
|
What must be present to have alveolar bone?
|
Teeth-Teeth must function to maintain alveolar bone health.
|
|
|
The alveolar bone is constantly changing and being remodeled in response to?
|
Normal funtion
Orthodontics |
|
|
Bundle Bone
|
Part of the Alveolar Process where sharpeys fibers attach to area of PDL attachment.
|
|
|
Lamellar Bone
|
Sheet like bone that composes the rest of the supporting bone
|
|
|
Cribiform plate
|
Descriptive term-cluster of perforations to allow nutrients and nerves to extend between the bone and PDL.
|
|
|
Cribiform Plate is AKA?
|
Lamina Dura, Alveolar bone proper and bundle bone
|
|
|
Sharpeys fibers are?
|
Bundles of collagen fibers embedded in the bundle bone and is connected to the cementum of the tooth.
|
|
|
Sharpeys fibers appear?
|
At regular intervals with interstitial spaces between them. They contain blood vessels, nerves, and lymphatics.
|
|
|
Orthodontic movement causes?
|
Remodeling of Alveolar bone proper.
Compression is placed on the bone in the direction that the tooth is being guided to move. |
|
|
Orthodontic pressure causes?
|
Osteoclastic activity and bone resorption. Tension on opposite side of tooth and bone formation occurs.
