Sticky bone (Fig.5 *) and PRF is used at #3 for hemostasis, while a 5x5.7(3) mm pair (final) abutment is used to hold acrylic dressing in place.  No suture is applied.  In fact the abutment at #13 fell out a few days earlier.  Local anesthesia is administered for placement of a 4x3 mm healing abutment.  The implant at #14 is uncovered with placing a 6x4 mm heal abutment.

病人有糖尿病，为了促进伤口愈合，3号牙（第一磨牙）拔除后放置粘性骨块（图五 *）和PRF膜。为了避免缝合，第二前磨牙种植后两个月，放置基台（5x5.7(3)mm，以前是愈合基台，图一）。然后自凝树脂覆盖拔牙创，并卡入基台和第一双尖牙周围固位，相当于牙周敷料，固定性强多了，称为树脂敷料（acrylic dressing）。
