Breast Implant Types — Every Option Explained

Fill Type: Saline vs Silicone

Saline implants contain sterile salt water. They are inserted empty and filled during surgery, requiring a smaller incision. If they rupture, deflation is immediate and visible, and the saline is safely absorbed. They tend to feel firmer than silicone — some patients describe a slight rippling feel, particularly in women with less natural breast tissue. FDA-approved for patients 18 and older. Silicone gel implants are pre-filled with cohesive silicone gel that feels very similar to natural breast tissue. They require a slightly longer incision. Rupture is "silent" — the cohesive gel tends to stay contained — requiring periodic MRI monitoring. FDA-approved for patients 22 and older. Silicone is chosen by the vast majority of augmentation patients for its more natural feel.

Shape: Round vs Anatomical

Round implants provide the same projection regardless of orientation — if they rotate, the result is unchanged. They tend to create more upper pole fullness. Most commonly used shape. Anatomical (teardrop) implants are designed to be fuller at the bottom to mimic the natural breast slope. They must have a textured surface to resist rotation; if they rotate, the result is distorted and may require corrective surgery. Used for specific aesthetic goals, particularly in breast reconstruction, or where a more "natural" slope is desired.

Surface: Smooth vs Textured

Smooth implants have a smooth outer shell and can move freely within the implant pocket. They are associated with a more natural movement. Textured implants have a rough surface that allows the surrounding tissue to adhere, reducing movement and rotation. Required for anatomical implants. Textured implants have been associated with a very rare type of implant-associated lymphoma (BIA-ALCL) and many manufacturers have withdrawn highly textured devices; discuss current guidance with your surgeon.
