title: [Comparative animal experimental study on the importance of the surface structure for the stability of extension implantations].
abstract: An animal experimental study was undertaken where the embedding of extension implants with a smooth or porous surface was histologically examined. Under extreme functional stress there occurs a mobility of the implants with the formation of a broad connective tissue zone, inflammatory reactions and ingrowth of epithelium, which is independent of the surface structure. Implants under less stress show a narrower connective tissue layer which narrows itself further if the surface is porous. The possible causes of this tissue reaction are discussed.
