Levels of osseointegration of blade-/plate-form implants

The blade-/plate-form implant is the only endosseous implant which has proved to be successful under three different types of integration: fibrous integration, when the layer of fibrous or collagenous tissue interspersed between implant and bone is less than 125 microns; fibro-osseous integration, when there is a combination of thinly defined fibrous connection with 22% or less direct bone contact with the implant; and osseous integration, when there is 23% or more direct bone-to-implant contact, with no evidence of fibrous connective tissue anywhere. The blade implant is an unique versatile device which has passed with success the test of time (some of them being in function for as long as 28 years) and deserves more attention from implantologists around the world.
