This comparison often comes down to whether you want a mainstream, heavily-studied implant or one of Polytech's distinctive specialist options.
Mentor
Established, predictable, with extensive data and a broad smooth/round range. A common default for first-time augmentation.
Polytech
German manufacturer offering polyurethane-coated shells (which tissue grips and which some evidence links to lower capsular contracture) and the lightweight B-Lite range.
Deciding factors
Consider whether polyurethane or lightweight technology is relevant to your case (for example, a history of capsular contracture, or large-volume goals on thin tissue). Surgeon experience with the specific product is key.
