Three different membranes were tested for guided bone regeneration in
8-mm unicortical trephine defects in rabbit tibia. All experimental an
d control defects healed with bone. The critical size defect in rabbit
tibia is larger than 8 mm, because control defects, 8 mm in diameter,
healed spontaneously. Around remnants of the biodegradable Polyglacti
n 910 mesh (Vicryl(R)), a diffuse infiltration of inflammatory cells w
ith multinuclear giant cells developed. However, the bone healing was
not impaired by the infiltrate. Around the Gore-Tex(R) membrane and ar
ound remnants of the Alzamer(R) a few lymphocytes were observed, but n
o multinuclear giant cells were noted.
