It used to be that deflation rates were 1% per year per implant. That meant that you could tell a client to expect a 20% chance of one of their implants deflating over a 10 year period. However, due to the wonderful improvements in implant technology that we have witnessed over the last couple of years, the most current statistics have shown a 3 to 7 % rate of deflation over 10 years. These studies have been performed by the Mentor and Inamed Corporations, both of which provide extended 10-year implant warranties.
