The shells of all MENTOR^® Breast Implants and Tissue Expanders are constructed from medical-grade silicone elastomer. The shells are then filled with either our medical-grade, cohesive silicone gel during the manufacturing process or saline at the time of surgery by the surgeon

MENTOR^® MemoryGel^® Breast Implant's shell physical properties are designed to exceed industry strength standard.¹²

MENTOR^® MemoryGel^® Breast Implants have been shown to have low gel bleed (gel diffusion).¹³ The overall body of available evidence supports that the extremely low level of gel bleed (gel diffusion) for MENTOR^® MemoryGel^® Breast Implants is of no presently known clinical consequence.¹³

Platinum is the only metal added during the manufacturing process for the silicone gel and shells of breast implants and tissue expanders. Scientific evidence supports that the low level of the specific type of platinum used in breast implants that may diffuse through the shell doesn’t represent a significant health risk.¹⁴
