As planned, two implants are placed with insertion torque ~ 50 Ncm (Fig.4: 5x13 and 5x11.5 mm for #30 and 31, respectively).
Collagen plug (orange) is inserted in the apical portion of the distal socket (blue outline), while autogenous bone harvested during osteotomy is mixed with Osteogen (Hydroxyapatite) and placed in the remaining sockets as well as in the mesiobuccal aspect of the implant at #30 (where threads are exposed) (red circles).
Emergency implantation is more likely associated with imperfection. The implant at #30 is placed slightly distal (compare the white lines and measurements in Fig.2, 5). When the crown of #31 is removed, the position of #30 initial osteotomy site tends to be distal.
