OPRO
The Product
OPRO is a global leader in custom-fit and self-fit mouthguards, used by professional and amateur athletes across a wide range of sports. The company is recognised for its innovation, including being the first mouthguard manufacturer to achieve CE Type Certification to the latest standards and a recipient of the Queen’s Award for Innovation.
The product range includes:
- Custom-fit mouthguards created using dental impressions and digital modelling
- Self-fit mouthguards designed for accessibility and ease of use
- Protective storage cases designed for safe transport and hygiene
Biomaster antimicrobial technology is integrated into both the mouthguard material and the storage case, providing consistent product protection across the full user experience.
This integration is particularly suited to polymer-based products like EVA mouthguards, where the additive can be evenly distributed throughout the material during processing, ensuring long-term durability and performance.
The Challenge
Mouthguards are exposed to one of the most challenging hygiene environments of any consumer product. They are placed directly into the mouth, stored in enclosed cases, transported in bags, and repeatedly reuse, often without thorough cleaning between uses.
This creates an ideal environment for microbial contamination, odour development, and material degradation over time. For a premium brand like OPRO, which supplies elite athletes and organisations including national rugby and boxing teams, maintaining product performance alone was no longer enough.
There was a clear need to enhance hygiene performance in a way that:
- Did not rely on user behaviour (e.g. cleaning routines)
- Would last for the lifetime of the product
- Would not compromise comfort, safety, or material integrity
- Could be integrated seamlessly into existing manufacturing processes
At the same time, OPRO wanted to strengthen product differentiation in an increasingly competitive sports protection market.
The Solution
To address these challenges, OPRO partnered with Addmaster to integrate Biomaster antimicrobial technology directly into both the mouthguard and its storage case.
Unlike surface coatings, Biomaster is incorporated into the material during manufacturing, ensuring that the antimicrobial protection is intrinsic to the product and does not wear off over time.
The technology works continuously to inhibit the growth of bacteria on the surface of the product, helping to maintain a cleaner and more hygienic mouthguard throughout its lifetime.
This approach allowed OPRO to deliver a passive, always-on hygiene solution that required no change in user behaviour while aligning with the brand’s premium positioning and commitment to innovation.
The Results
The integration of Biomaster delivered both functional and commercial benefits for OPRO.
From a product performance perspective, the technology helps to:
- Inhibit the growth of bacteria on the mouthguard and case
- Maintain a cleaner and more hygienic product between uses
- Reduce odour development associated with microbial build-up
- Support product longevity by protecting the material
From a commercial standpoint, the addition of antimicrobial technology has provided OPRO with a clear point of differentiation in the market.
As noted by the OPRO team, incorporating Biomaster has helped create a unique selling point, adding value to the product range and strengthening competitive positioning.
Crucially, this differentiation is achieved without adding complexity for the end user, reinforcing OPRO’s reputation for combining performance, safety, and innovation in sports protection.
