NOVEL APPROACH FOR MEMBRANE PERFORATION REPAIR USING PLATELET-RICH FIBRIN AND AUTOLOGOUS FIBRIN GLUE DURING SINUS FLOOR ELEVATION

抄録

This study described a method for membrane perforation repair during sinus lift using platelet-rich fibrin (PRF) and autologous fibrin glue (AFG). It also highlighted the importance of using a microscope during surgery. PRF promotes wound healing and tissue regeneration. AFG forms sticky bone when mixed with bone material on a glass dish, which accelerates tissue healing and minimizes bone loss during healing.

A large perforation was created in the Schneiderian membrane at the peak of the septum after opening the lateral window, during lateral wall sinus elevation in a 43-year-old woman. PRF was placed at the perforation site, which prevented bone material from entering the sinus cavity, followed by the placement of sticky bone. The implant was placed 7 months after the sinus lift. Computed tomography (CT) revealed stable bone-like structures around the implant.

PRF was used to repair the perforated Schneiderian membrane during transcrestal sinus lift in a 38-year-old woman as the sole filling material. Implant placement was followed by placement of bone material in the gap. CT revealed a bone-like structure around the implant after 6 months.

The use of PRF and AFG under microscopy simplifies membrane perforation repair, as they use minimally invasive techniques, without additional surgery.
