What matters: the implant surface
For the body, an implant is a foreign body. As a natural reaction, it forms a capsule of connective tissue around the implant. This capsule will build around any implant and, by and by, the capsule tends to shrink. This process can deform the breast implant, and the result is called capsular fibrosis or capsular contracture. It may be very painful for the patient and the implant has to be exchanged.
With smooth implants, capsular contracture occurs frequently. Implants with a roughened or textured surface lessen the risk for capsular contracture. Silicone implants with the POLYTECH Health & Aesthetic Microthane® coating (micropolyurethane-foam) reduce the risk for capsular contracture significantly.
The tissue around a Microthane® implant has a different structure compared to the capsule around a smooth implant. This is due to the foam which allows tissue ingrowth and reduces the tissue’s tendency to shrink.
