As planned, two implants are placed with insertion torque ~ 50 Ncm (Fig.4: 5x13 and 5x11.5 mm for #30 and 31, respectively). *: mesial and distal sockets.

The patient returns for final restoration 3.5 months postop; it appears that the mesial and distal sockets of the site of #31 decrease in size and increase in bone density (Fig.6).

There are no sockets at #31 11.5 months post cementation (Fig.7).  The cortex forms between the implants 3 years 9 months post cementation, but caries is not detected (Fig.8 *).  The crown #32 dislodges 10 months later.  The tooth is extracted without bone graft because of being far from the nearby implant.
