Panoramic X-ray: Due to the limited amount of remaining bone, lateral approach for the posterior part of sinus is preferred.
Clinical photograph of occlusal surface of the maxillary left edentulous ridge (#26 and #27) before surgery.
Full thickness flap with papilla preserving incision was made.
The C-reamer was used to obtain a thin bone disk for lateral sinus graft. Drilling with 2000 rpm or faster is recommended.
A bony window was prepared in between #26 and #27.
Careful detachment of the think bone disk from the membrane using the sinus elevator in Sinus All Kit.
A Combination of Calpore(HA+β TCP) and autograft was used for the sinus graft.
After bone grafting, 2 implants (IT-II(Neobiotech, Korea)) were placed simultaneously.
2 implants(Ø5.0*10mm) were successfully placed in the site of #26 and 27, achieving 30N/cm of insertion torque.
Ø6.0 Healing abutments were connected and simple interrupted sutures were performed in between healing abutments.
One month later, good soft tissue healing was observed.

3.5-year follow-up panoramic view and marginal bone level and sinus graft material has been well maintained.
