Osseointegration

  1. direct structural and functional connection between the implants and the bone. 
  2. [ hemidesmosomes like structures, no CT insertion, no Sharpey’s fibers ] – the first cell to contact the implant is osteoblast 
  3. It’s normal to have up to 2 mm of bone resorption around the neck of the implant in the first year. 
  4. Implants only have a periosteal blood supply
  5. No innervation & no proprioception 
  6. Since implants do not have CT [ no shock absorption ] – if there is any traumatic occlusion or excessive force it will lead to bone resorption [ cervically] or the implant might mechanically fail.
