The aim of this study was to determine the effectiveness of two biomaterials, fibrin-rich plasma (PRF) and collagen membrane in guided bone regeneration. Materials and method: Thirty male guinea pigs were used, weighing between 900 and 1100 g., divided into three groups of 10 guinea pigs each (Group A: control, group B: collagen membrane and group C: fibrin-rich plasma). Each group had a 2-mm unilateral mandibular bone defect. Group A did not receive any biomaterial; in groups B and C the biomaterials were used in the bone defects. After 15 and 30 days of healing, histological sections were performed to evaluate the amount of fibroblasts, osteocytes and osteoblasts. Results: After 15 days, group C formed 40.6 ± 8.08 osteocytes / camp and group B 27.6 ± 4.72 (p <0.05); After 30 days, group C: 30.6 ± 11.55 and group B: 23.6 ± 3.85 (p> 0.05). Conclusion: During the first 15 days of healing, PRF induces a greater cellular proliferation than the other groups in a significant way; after 30 days, the proliferation is similar to the collagen membrane group without significant differences.
