Comparison of a 250cc implant with a 450cc implant. Note the difference in diameter of the larger implant. Larger implants will create a cleavage which is closer together. However with larger implants, a smaller framed women should consider if the total diameter will crowd the horizontal dimension across her chest wall.
The implants shown here are round with a smooth texture. There are two manufacturers of implants: Mentor and McGhan. Both vendors carry warranties on their implants and each offers lifetime product replacement for the implants.
