All implants harden over time. The percentage for capsular contracture is 1% per year. All implants need to be replaced within 10-15 years.
This is what you are referring to. Capsular contracture happens to some extent in all patients who have implants. There are different grades and what you want is a Grade I. The significant contracture happens in about 7.5% of saline augmentations and about 9% of silicone augmentation. This is some new data from one of the implant companies. To try to avoid this there are a lot of little things that are done in the operating room and after surgery the patients are instructed to massage vigorously to prevent this. Hope that helps
