Research is looking at implant reconstruction with a tissue expander using a dermal matrix product to cover the implant compared to using skin and muscle to cover the implant. The dermal matrix essentially forms a âslingâ that helps form a pocket and support the lower portion of the implant, holding it in position.
Silicone rubber is used for tissue expanders, the outer shell of both saline-filled and silicone gel-filled breast implants, and as an onlay material for the augmentation of the bony skeleton and soft tissues. However, silicone rubbers are relatively weak and tend to tear, leading to implant failure.
