KeySplint Hard Clear offers the precision and reliability that orthodontists and laboratories need to improve patient care.
Explore why KeySplint Hard Clear is the essential choice for creating transparent, long-lasting braces that delight patients and inspire professional confidence:
Ideal transparency for aesthetic braces:
Unlike traditional dental resins, which often exhibit a slight tint, KeySplint Hard Clear is distinguished by its crystalline transparency, making it the perfect solution for applications where aesthetics come first. From invisible braces to sports aligners, this resin guarantees a discreet, professional finish that enhances patient satisfaction. Its clarity doesn't just beautify fixtures: it also enables better inspection of fit and detail during production, ensuring that every piece meets the highest quality standards.
Superior strength and durability for extended use:
Designed to last, KeySplint Hard Clear is engineered to withstand the stresses of daily use in demanding dental applications. With a flexural strength of 60-65 MPa and a flexural modulus of 1510-1600 MPa (ISO 20795-2), this resin offers the rigidity needed for rigid aligners, post-traumatic dental immobilizers and anti-snoring appliances. Its 9% elongation at break (ASTM D638) guarantees a non-brittle finish, enabling appliances to withstand stress without cracking or warping.
Furthermore, KeySplint Hard Clear features low water absorption (18 μg/mm³), making it highly resistant to moisture absorption-a crucial factor in maintaining dimensional stability in intra-oral environments. From everyday braces to sports mouthpieces exposed to high forces, this resin ensures long-lasting performance, giving you and your patients total peace of mind.
Biocompatible and Safe for Intra-Oral Use:
Safety is essential in dental applications, and KeySplint Hard Clear exceeds all expectations with its Class IIa biocompatibility certification (ISO 10993-1). Approved for prolonged intra-oral use, this resin is FDA-cleared (510k-cleared) in the USA, CE-marked in Europe, and approved in Australia and New Zealand for the manufacture of orthodontic, anti-snoring and retainer appliances. Although Health Canada approval is pending in May 2025, its worldwide certifications make it a reliable choice for dental professionals worldwide.
Free from plasticizers, softeners and Bisphenol A (BPA), KeySplint Hard Clear guarantees patient safety while delivering high performance. Its anti-stain and abrasion-resistant properties enhance its suitability for prolonged use, maintaining clarity and functionality even after prolonged exposure to oral conditions.
The KeySplint Hard Clear fits perfectly with our mission to provide innovative 3D printing solutions across Europe. Here's why it distinguishes itself:
- Aesthetic excellence: Its crystal-clear finish meets the growing demand for invisible braces, increasing patient satisfaction.
- Reliability and Durability: With robust mechanical properties, it guarantees appliances that last, even under demanding conditions.
- Safety first: Biocompatible and free from harmful additives, it puts patient well-being first.
- Versatility: Ideal for a range of applications, from rigid aligners and retainers to sports aligners and anti-snoring appliances.
Perfect integration into your 3D printing workflow
KeySplint Hard Clear is designed to work effortlessly with a wide range of DLP and LCD 3D printers operating at wavelengths of 385-405 nm. Its optimized viscosity ensures smooth printing, minimizing the risk of failures and reducing material waste.
Here's how it fits into your workflow:
Exposure time: Approximately 2-3 seconds per layer (0.05 mm layer height) on standard DLP printers, for fast, efficient production.
Post-Processing: After printing, rinse with isopropyl alcohol (IPA) for 5-10 minutes, followed by a 10-15 minute post-cure under a 405 nm UV lamp for complete polymerization.
Curing depth: Approx. 4 to 5 mm, ensuring homogeneous curing for complex dental models.
The compatibility and ease of use of this resin make it a seamless addition to your existing equipment, allowing you to concentrate on creating high-quality appliances without the hassle of complex adjustments.
