Stability Where It Matters, Confidence That Lasts.
Designed for safety and long-term performance, MESMO® is POLYTECH’s fine microtextured implant surface with Open Gas Diffusion Surface (GDS) finishing technology. This surface supports tissue integration and reduces the risk of implant displacement.
Backed by extensive clinical evidence, MESMO® implants allow stability where it matters most – giving patients long-term confidence they can rely on.
MESMO® – Unique Surface Finishing Technique
True performance goes far beyond surface classification.
The MESMO® fine-microtextured surface is engineered with distinctive characteristics that set it apart in the field of breast implant technology. Its Open Gas Diffusion Surface (GDS) technology is created through a precise manufacturing process: thermal decomposition of ammonium carbonate over a single layer of uncured medical-grade silicone.
This advanced process and surfacing technology creates a uniform fine microtexture as part of the final implant surface, without the use of mechanical abrasion. The result is a surface structure that reflects our Mede in Germany quality and the focus on innovation in implant manufacturing.
Lowest expression of α-SMA
Another study has shown that MESMO® demonstrates the lowest expression of α-SMA compared to nano-textured implants, indicating reduced myofibroblast activation. Supporting the formation of a more stable, less fibrotic capsule.1
In the same peered reviewed study MESMO® surfaced implants are reported to have a proven Stability with reliable results1:
- Low rate of capsular contracture (Baker grade III & IV)
- Stable capsule formation for predictable results
- Reduced inflammatory response and fibrosis
- Reduced myofibroblast activation: Lower α-SMA levels indicate reduced fibrosis
- IMPROVED REMODELING: Supports less fibrotic capsule formation
- ENHANCED INFLAMMATORY RESPONSE: Promotes balanced inflammation and neoangiogenesis
Safety and Performance in 5-Year Clinical Study
- A 5-year post-market surveillance (PMS) study evaluated 919 patients who received MESMO® fine-microtextured breast implants. The analysis reported low rates of complications over the study period: 0.9% capsular contracture (Baker grades III–IV), 0.5% revision surgery, and 0.4% implant removal.2
- These findings form part of the peer-reviewed clinical evidence highlighting the safety, performance, and reliability of MESMO® implants.
Clinical Performance
Clinical Outcomes with MESMO®
In a peer-reviewed evaluation of surgical cases performed by Dr. Paolo Montemurro, outstanding results were reported for patients receiving MESMO® fine-microtextured breast implants.
Within his patient series during the study period:
- No cases of implant rupture were observed.
- No instances of bottoming out were reported when compared to other breast implants used in his practice.
- Furthermore, there were no cases of BIA-ALCL documented in this cohort.
These results, published in the Aesthetic Surgery Journal in 2024 and 2025, contribute to the growing body of clinical evidence on implant surface technology and the performance profile of MESMO®.
Proven Patient Satisfaction
A post-market surveillance study on MESMO® fine-microtextured breast implants reported 93.9% patient satisfaction with aesthetic results2. As a patient-reported outcome, this finding offers valuable insight into real-world performance, showing how MESMO® combines advanced surface technology and supports results that meet patient expectations in aesthetic breast surgery.
Such outcomes highlight the importance of measuring both clinical quality and patient experience when evaluating breast implant technology.
MESMO® Portfolio
With over 270 configurations, the MESMO® portfolio offers a wide variety of implant shapes, sizes, and projections — including round and anatomical options such as Même®, Replicon®, Opticon®Plus, and Opticon®. Also available with B-Lite® lightweight implants.
To support your decision-making, POLYTECHselect makes it easy to identify the right implant for your patient online.
