If Platelet Rich Plasma (PRP) can guarantee the quantity of 3 times that the normal blood flow in bone regeneration and soft tissue healing process, it is assumed that it approaches the mesenchymal stem cell, and raises the osteogenesis. We removed prominent gutta-percha in the maxillary sinus for part of the root perforation and did the operation of the maxillary sinus floor augmentation.We reports the case that the new bone created by PRP which is extracted making use of the method of concentrating PRP of the necessary quantity and PRP clot while guaranteeing the blood platelet quantity with the filter and the part of root perforation repaired. Platelet Rich Plasma (PRP)は骨再生や軟組織治癒過程において通常血流の3倍量が確保できれば間葉系幹細胞に働きかけ, 骨造成を高めるとされている.本文では, 歯根穿孔部より上顎洞内に突出したガッタパーチャの除去および上顎洞底粘膜挙上術後にフィルターで血小板量を確保しながら必要量のPRPを濃縮する方法を用いて抽出したPRPと多血小板血漿凝集隗(PRP clot)による骨造成と歯根穿孔部の修復おこなった症例の報告を行う.
