Porcine Resorbable Collagen Matrix Shows Good Incorporation of Liquid Platelet-Rich Fibrin In Vitro

Int J Oral Maxillofac Implants. 2023 Jul-Aug;38(4):768-774. doi: 10.11607/jomi.10092.


Purpose: To evaluate the incorporation of liquid platelet-rich fibrin in different collagen matrices in vitro. Materials and Methods: Collagen matrices with liquid platelet-rich fibrin were used and divided into the following test groups (n = 5): Mucoderm (MD), Mucograft (MG), and Fibro-Gide (FG). After incubating the collagen matrices in liquid platelet-rich fibrin, histologicl and fluid absorption capacity analysis were performed. Intergroup comparisons of cell count, blood plasma penetration area, and fluid absorption capacity were performed using one-way ANOVA and Tukey tests. Intragroup comparisons of fluid absorption capacity were made using the independent t test with a 5% significance level. Results: Descriptive qualitative analysis showed total incorporation of liquid platelet-rich fibrin in the FG group, while the MG and MD groups showed only partial and shallow incorporation, respectively. There was a statistically significant difference among the three groups regarding inflammatory cell infiltration (P = .000), with the FG group presenting the highest number of cells in the matrices (577.15 ± 54.88). The FG group showed an area of total blood plasma penetration into the matrix, followed by the MG group with partial penetration, and the MD group with minor penetration area (P = .000). Considering the fluid absorption capacity analysis, only groups FG and MG were statistically different when comparing the liquid platelet-rich fibrin absorption coefficient (P = .017), with higher absorption in group FG (14.30 ± 3.35). Conclusions: The FG collagen matrix showed a good capacity for liquid platelet-rich fibrin incorporation in vitro.
