Two of the most discussed brands in UK private practice. Neither is simply "better" — they reflect different philosophies.
Motiva
Newer, marketing-forward, with SmoothSilk surface, single-piece TrueMonobloc shell and ergonomic gel. Strong patient interest; long-term independent data is still accumulating relative to legacy brands.
Mentor
One of the most established brands, with a very large body of long-term clinical data and predictable, widely used products.
How to choose
If a long published track record reassures you, Mentor's depth of evidence is a strength. If you are drawn to newer surface and shell technology, Motiva is worth discussing. Most importantly, choose a surgeon experienced with whichever implant they recommend.
