Dani, I used Dr. Tcheupdjian (I actually had to look his name up for the spelling..it's a crazy one!) for my breast aug about 13 years ago. I've had zero problems, so I have to say he is pretty good. Most people will tell you they need to be replaced 10 years, but I wouldn't be surprised if these last another 20. I can't recall the name, but can search for the "device" card of you like. They are saline textured that much I know. I went up two sizes. I think he used about 300cc in each one? The funny thing..my husband doesn't even know I have implants! I keep telling myself I'm going to tell him one day, but I think he might accuse me of false advertising.
Anyway, really happy with Dr. T..he is mainly the goto guy for lipo, but I had a friend that used him and was pleased.
ETA- they were also placed under the muscle. Also, they looked like bolt ons for a very long time, just to warn you. They didn't look 100% natural (drooped a bit) for about 5 years.
