After removal of granulation tissue distal to the osteotomy, a larger implant is inserted with ~15 Ncm; mixture of autogenous bone and allograft is packed (Fig.5 *).  The latter is covered by 12x12 mm BioXclude and sutured with 4/0 Chromic Gut tension free.最后放置大一号植体，扭力也大一些，周围放置大颗粒骨粉， *。那天没有抽血，骨粉表面覆盖胎盘膜，BioXclude，无张力缝合。术后6.5月切开证实植体上面没有骨质覆盖（如图七：*），第一螺纹可能暴露（>）。螺纹周围骨质密度增高。
