Advantage is that an immediate provisional (Fig.2 yellow lines; Fig.3 P) has an ideal emergency profile so that there is less chance of food impaction associated with the future permanent crown.  Red dashed line: mesial and distal crests.  Bone graft appears to be integrated to the native bone and the implant 14 months postop (Fig.5).32岁女左上6即刻种植（图2：4.5x10毫米），内提升，使用临时基台（5.2x8(2)毫米）即刻修复，有可能建立理想emergency profile （黄线，即临时牙冠），红虚线代表近中，远中牙槽嵴，后者与植体/基台之间是骨粉。术后14个月，植体螺纹没有暴露，骨粉好像与植体和牙槽嵴整合了（图5），放置修复基台。
