osteointegration Flashcards
new bone forms on old bone
distance
bone forms on surface of implant
contact
osteogenic become what
osteoblasts
what do osteoblasts do (contact)
lay down new bone matrix on implant surface
what is first to be secreted by osteoblasts
cement line (calcified collagen-free matrix)
what does cement line separate
new bone from old bone
what forms after cement line
collagenous and mineralized ECM of bone
what is more stabilizing for implant
contact osteogenesis
what happens after osteogenic cells move to old bone surface
they become osteoblasts and then become polarized
osteocytes become ____ in the bone matrix (distance)
buried
why do the osteocytes die
they are cut off from their vascular supply as they get buried in their own matrix
integrity of the bone is maintained by
osteogenic cells replace osteocytes that get buried
what separated the implant from bone in distance
osteoblasts
why cant osteoblasts migrate to the surface
their processes are buried in matrix
contact is the sum of what
osteoconduction and bone formation
