Zinkh NV

Zinkh NV, founded in Ghent, Belgium in 2019, manufactures Elemental PerioPlast®, a patented zinc-infused thermoplastic stent material designed to protect palatal donor sites following free gingival graft harvesting. The product eliminates the need for sutures, reducing patient pain and morbidity while improving healing outcomes. PerioPlast® is heat-moldable at 90°C, chair-side ready within one minute, and provides stable retention for five days of use. The material is bacteriostatic due to zinc infusion and exhibits high biocompatibility. The company's core competency is proprietary polymer infusion technology with zinc, enabling tissue-friendly, antimicrobial surgical materials. Elemental stents are clinically validated in a published randomized controlled trial (Clinical Oral Investigations, July 2023) and represent an advancement over traditional techniques including sutured collagen sponges, laboratory-fabricated stents, and cyanoacrylate dressings. The company serves periodontists and oral surgeons across the EU and US (FDA-approved since January 2025). Products are sold through an online shop at shop.withelemental.com and marketed at major periodontal conferences (EuroPerio, NESP, Osteology). The company positions itself as a partner for soft-tissue management innovation and indicates plans for expanded indications and materials beyond current palatal graft applications.
