Preoperative radiograph

#15 and #25: Root rest
Immediate placement and Class III sinus bone graft using the SCA kit with simultaneous implant installation was planned on #15

Surgery date: Nov 8, 2016

도형15
The root apex is near to the inferior cortical wall of the sinus which is concave.

도형4
Extracted root rest length was about 10mm. The extraction site was drilled 1 to 2mm deeper than implant length.

도형7
2.4mm diameter S-reamer of the SCA kit with 4mm, 5mm, and 7mm stopper were used at the area of #15.

도형8
S-reamer was applied for making a hole in the cortical bone at the maxillary sinus floor.

도형9
Allograft 0.3cc(RegenOss™) was inserted into the space of the elevated sinus membrane. Bone graft material was applied with the bone carrier of the SCA kit. Bone graft material of the apical side was inserted with the bone condenser from the SCA kit.

도형3
Periapical radiograph after bong graft with sinus lifting. Bone material was seen in the sinus elevating the membrane.

도형10
After bone graft, trans-mucosal CMI IT-II implant (4.0X10.0) was ready for placement in the area of #15.

도형11
Trans-mucosal (non-submerged) type implants was positioned in the middle of the socket. Buccal and lingual space was filled with bone materials after placing the cover cap. The initial torque of the #15 fixture was about 30 Ncm.

도형12
2mm height healing abutment was inserted after bone graft. No suture was performed.

도형13
Periapical radiograph after implant placement membrane was well-elevated by the bone material around implant apex. The apex of the implant was placed 1-2mm into the sinus.
