Some textured silicone breast implants with high average surface roughness ('macrotextured') have been associated with a rare cancer of the immune system, Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL). Silicone elastomer wear debris may lead to chronic inflammation, a key step in the development of this cancer. Here, we model the generation and release of silicone wear debris in the case of a folded implant-implant ('shell-shell') sliding interface for three different types of implants, characterized by their surface roughness. The'smooth'implant shell with the lowest average surface roughness tested (R a= 2.7±0.6 μm) resulted in average friction coefficients of μ avg= 0.46±0.11 across 1,000 mm of sliding distance and generated 1,304 particles with an average particle diameter of D avg= 8.3±13.1 μm. The'microtextured'implant shell (R a= 32±7.0 μm) exhibited μ avg= 1.20±0.10 and generated 2,730 particles with D avg= 4.7±9.1 μm. The'macrotextured'implant shell (R a= 80±10 μm) exhibited the highest friction coefficients, μ avg= 2.82±0.15 and the greatest number of wear debris particles, 11,699, with an average particle size of D avg= 5.3±3.3 μm. Our data may provide guidance for the design of silicone breast implants with lower surface roughness, lower friction, and smaller quantities of wear debris.
