Sinus grafting using recombinant human tissue factor, platelet-rich plasma gel, autologous bone, and anorganic bovine bone mineral xenograft: histologic analysis and case reports.

Purpose: The purpose of this study was to analyze healthy bone formation by means of histology and immunohistochemistry after grafting with a mixture of autologous ground calvarial bone, inorganic xenograft, platelet-rich plasma (PRP), and recombinant human tissue factor (rhTF).

Materials And Methods: Maxillary sinus floor augmentation was performed on 3 patients by grafting with 5 to 10 mL of a paste consisting of autologous powder from calvarial bone (diameter < 1 mm), 50% v/v anorganic bovine bone mineral xenograft (PepGen P-15, a new tissue-engineered bone replacement graft material), PRP (1.8 x 10(6) platelets/mm3 plasma), and about 1 microg rhTF.

Human recombinant tissue factor, platelet-rich plasma, and tetracycilne induce a high-quality human bone graft: a 5-year survey.

Purpose: To increase human bone graft regeneration and quality by the use of a mixture containing autologous ground calvarial bone, human recombinant tissue factor (rhTF), platelet-rich plasma (PRP), and tetracycline.

Materials And Methods: Maxillary sinus floor augmentation was performed on 18 patients by grafting a "bone paste" made of PRP (1.8 x 10(6) platelets/mm3 plasma), about 1 microg rhTF, calvarial bone chips (2 to 5 mm in size), and tetracycline (10 to 30 microg/mL preparation).
