The implant seems to remain non-osteointegrated 3.5 months postop (Fig.9).  Later a 6.8x4 mm healing abutment is placed with occlusal clearance.  X-ray will be taken every 2-3 months until osteointegration occurs.  Although the bone density around the implant increases nearly 6 months postop (Fig.10), the implant remains tender when a 5x4(4) mm pair abutment is tightened.  The healing abutment is reused.  The bone density around the implant increases 11 months postop (Fig.11).  Uncover is done with 5.5 mm profile drill.  术后12个月松开愈合基台时下面植体疼痛，植体好像种得太浅（图十一）。
