According to research the cohesive gel implants (they only do one type in the regular CUI implant range) the Inspira/ Natrelle range because they have a more cohesive/slightly more solid, harder filling than the standard silicone or saline fillings had much better, lower rates of cc. All the implants MYA use as standard are textured, I think you have to pay more for smooth, and again the Inspira/Natrelle are more expensive.
Also, the larger the implant, the more chance of cc according to lots of studies. I don’t think you can predict it though, as every person will have a different reaction but try not to worry as it did occur they would take it out and place another one in it’s place when your body had had a chance to recover xx
