Fig.5 (immediately postop): A 6x17 mm implant is placed.

Fig.9 (6 months postop): Bone density around the coronal aspect of the implant increases (*).  Apical resorption occurs.

Eleven months post bonding (17 months postop), there is cortical bone formation at the mesial and distal crests (Fig.14).  It remains the same 1 year 10 months post bonding (Fig.15).  There is no bone loss 3 years 5 months post cementation (Fig.16).  In fact the crestal cortical bone thickens.
