  1. Intraoral photo of a patient who came to the hospital with pain due to a tooth fracture.



  2. CBCT radiograph showed that the inflammation had already spread to the maxillary sinus, and the apical lesion was also seen in the first molar.



  3. 2 months after tooth extraction. The tooth extraction site and the inside of the maxillary sinus healed well.



  4. Intraoral photo of maxillary sinus graft day.



  5. A lateral window was formed using a piezo surgical machine.



  6. Small perforations of the membrane were observed in two places.

  7. A collagen membrane will be used to form the ceiling of the graft, including the puncture site.

  8. Block the perforations with a sufficiently wide collagen membrane.



  9. The graft material is inserted into the maxillary sinus. First, fill in the anterior region of the maxillary sinus.

  10. The graft was done.



  11. The outside of the graft surface was covered with the same membrane used above.



  12, CBCT immediately after maxillary sinus graft.


  13. 3.5 months after the graft, A simple simulation of implant placement was performed using CT.



  14. 2 implants were placed.
