Introduction: Polymethylmethacrylate (PMMA) is an inert, biocompatible, rejection-free filler that does not induce infection, necrosis, or tissue damage. It is a polymer used in various diseases and in facial and body sequelae of congenital or acquired diseases, and for aesthetic purposes too. The PMMA manufacturer claims that the product has been improved, purified, and standardized (3rd generation) with rigid microspheres regularity that does not allow phagocytosis, consequently, reducing the inflammatory reaction. Objective: To prove this statement, the present study was conducted, whose objective was to analyze the physical characteristics of the PMMA particles distributed by the two Brazilian companies. Results: The two samples showed no statistical difference, being virtually the same. Conclusion: The surface homogeneity and particle size confirmed the hypothesis of product improvement, which will positively reflect on the clinical results of the product application, this fact can be proven by future studies.
