KeySplint Soft™ is a premium 3D printing resin engineered for flexible, biocompatible dental appliances such as nightguards, splints, mouthguards, snoring devices, bite-planes, and bleaching trays. 

🌟 Why KeySplint Soft Stands Out

• Biocompatible & Medical-Grade — 510(k) cleared in the US, CE-marked (Class IIa), and approved in multiple global jurisdictions for safe intraoral use. 

• Strong Yet Flexible — Its unique formulation balances durability and elasticity, providing protection against conditions like bruxism while offering enhanced comfort and flexibility for daily wear. 

• Clear, Polishable & Aesthetic — Prints are transparent (or tinted), easily polishable, stain-resistant, and maintain color stability — ideal for visible appliances like mouthguards and bleaching trays.

• Compatible with Many Printers — Designed for DLP / LCD 3D printers using 385–405 nm light sources; validated across multiple open-source and commercial platforms. 

• Long Shelf Life & Reliable Performance — Offers a stable formulation with extended shelf life and consistent results for professional dental labs and clinics.

✅ Best For

Dental labs, clinics, and orthodontic practices needing to produce comfortable, patient-ready flexible appliances — nightguards, splints, mouthguards, snoring devices, or bleaching trays — with minimal post-processing, aesthetic finish, and reliable biocompatibility.
