Under Vs over the Muscle Placement for Gummy Bear Implants?

There are two good reasons for placing breast implants below the muscle. The first reason is that the breasts appear more natural particularly in the upper part. The second reason is that implants placed below the muscle have a significantly lower chance of hardening with time. Unless a patient has something unusual about her anatomy that would make a better appearance above the muscle, I place the breast implants below the muscle.

Hello,
Silicone gel implants are subject to less contracture (hardening) over the long term when placed under the pectoral muscles.
"Overs" may require more surgery over the long term to deal with this problem should it arise. 
Best Regards
 

I do all of my implants under the muscle. I feel it gives the most natural look and feel. I also believe it gives the best long term results.
