Radiological results of the P20B80, P10B90, P5B95, and autograft groups. The autograft group was considered to have fusion because the trabecular bridging between the upper and lower transverse processes was clear. In comparison, the volume of the graft with the three glass-ceramics types declined at 12 weeks postoperatively from the immediate postoperative (IPO) levels, and was, thus, thought to be resorbed.
