One-year follow up for the use of collagen for biological anchoring of acrylic dental roots in the dog.
Second premolars in both upper and lower jaws of 6 dogs were extracted and acrylic resin replicas were made of the roots. Horizontal channels were drilled across the root replica perpendicular to the long axis. Before implantation, the prepared root replicas were immersed in a solution of native collagen. One year after implantation, proliferation of connective tissue and newly-formed viable bone were observed within the channel as well as surrounding the treated implants. All control implants without collagen treatment were rejected leaving chronically inflamed implantation sites.
