This study utilizes andf experimental model in beagle dogs in which chronic bifurcation defects are induced by passing a round bur through the denuded bifurcations of the premolars in the lower jaw (Ellegaard et al. 1973). Immediate spontaneous healing was avoided by inserting a steel wire through the created bifurcation defects. The wire was ligated over the crown and left in place for six weeks. A split mouth technique was used in order to compare the furcation lesions at two and nine months after creation. Histological observations and meansurements indicate that chronic lesions with characteristics similar to those in man were obtained.
