    Abstract

    Previous work has shown that the interfacial tissue response to pure titanium endosseous blade-vent dental implants in dogs can be influenced strongly by the biomechanical use of the implant. The surfaces of all 16 implants retrieved from our previous study were examined in an effort to evaluate (1) the response of the implant biomaterial to in vivo conditions and (2) the nature of any tissues which attached to implant surfaces. Implants were implanted for two, four, six and twelve months.

    No evidence of corrosion or release of titanium in adjacent tissues was observed. Implants did show bone and epithelial tissue attachment to the surfaces, but the quantity of such tissues was usually very small. Although functional versus nonfunctional implants in our previous research produced completely different interfaces, as seen in histology done after removal of implants from the tissues, the present work revealed no correlation between these interface structures and the tissue remnants which were scattered over tiny portions of the implant surface area.

    While the data from this study indicate the corrosion resistance of pure titanium in a dental implant application, the implant material plus several additional factors must be considered together in interpreting the total interfacial tissue response to a dental implant.
