The purpose of this study was to investigate the tissue reaction to three kinds of membranes, Gore-Tex Augmentation Material (GTAM), Vicryl, and Dura Mater, placed on bone defects around the titanium implants. Nine adult dogs weighing 15kg were used in this study. The dogs were sacrificed either 2, 4, or 12 weeks after placement. Vicryl was exposed 2 weeks after placement. Histologically, it was found that Vicryl was completely resorbed, Dura Mater was replaced with connective tissue at 12 weeks, and bone defects using GTAM and Dura Mater but not Vicryl were partially filled with newly-formed bone tissue. Active bone formation was observed in the space between membranes and pre-existing bone tissue.
