I currently have capsular contractions with Mentor and i am wondering if its worth replacing with the new Motiva since my doc said they have less chances of capsular contractions. My current implants are under coverage and I want to know if i should spend the money and replace with new brand or should I just exchange it with mentor again. Also my doc said if just the one be replaced there is a chance it will be uneven since the other one hasn't been touched.
