Will Motiva demi implants sit further apart than mini? (Photos)

The two variables controlling size are base width and projection. The Demi has more projection than the Mini and theoretically would have more volume for the same base width.

Generally speaking, wider implants will fill your breast out to a greater degree than a narrower implant, even if the narrow device has more volume. In your case, the 230 Mini is 2.5 mm wider, resulting in slightly less distance between implants than the Demi. If you were to bump up to the 285 Demi then you should see a very similar footprint with a bit more projection that the 230 Mini. With regards to recommended width, we try to stay within a range of 0.5 to 0.75 cm, but bumping up to the next profile (Mini to Demi) resets the base diameter at a narrower point. Your surgeon should be able to Vectra any of these implants for you to help you find the best fit.
