You have many questions about the types of implants… here several recommended by Dr. Eduardo Mejia :


Saline breast implants are filled with sterile salt water. Should the implant shell leak, a saline implant will collapse and the saline will be absorbed and naturally expelled by the body.
Saline breast implants provide a uniform shape, firmness and feel, and are FDA-approved for augmentation in women age 18 or older.
Silicone breast implants are filled with silicone gel. The gel feels a bit more like natural breast tissue. If the implant leaks, the gel may remain within the implant shell, or may escape into the breast implant pocket. A leaking implant filled with silicone gel will not collapse.
If you choose silicone implants, you may need to visit your plastic surgeon regularly to make sure the implants are functioning properly. An ultrasound or MRI screening can assess the condition of breast implants.
Silicone breast implants are FDA-approved for augmentation in women age 22 or older.
Gummy bear breast implants
Form-stable implants are sometimes referred to as gummy bear breast implants because they maintain their shape even when the implant shell is broken.
The consistency of the silicone gel inside the implant is thicker than traditional silicone gel implants. These implants are also firmer than traditional implants, but are thought to be less likely to break.
Gummy bear breast implants are shaped rather than round. They have more projection at the bottom and are tapered towards the top. If a shaped implant rotates, it may lead to an unusual appearance of the breast.
Placement of gummy bear implants requires a longer incision in the skin.
Round breast implants have a tendency to make breasts appear fuller than form-stable implants. Higher profile options can achieve even more projection.
Because round implants are the same shape all over, there is less concern about them rotating out of place.
Smooth breast implants are the softest feeling. These implants can move with the breast implant pocket, which may give more natural movement.
Smooth implants may have some palpable or visible rippling.
