SplintSmile Hard is a high-strength, biocompatible 3D printing resin developed by C.E.I.B.med for the fabrication of nightguards, occlusal splints, and sports mouthguards that require rigidity, long-term durability, and superior patient protection. It is engineered to deliver both the mechanical strength needed to withstand bruxism and occlusal forces, and the precision demanded by digital dental workflows.

Built for clinical reliability, SplintSmile Hard offers exceptional flexural strength—comparable to industry-leading nightguard resins—with tested values around 119 MPa and a flexural modulus of 2,452 MPa. These properties ensure the final appliance remains dimensionally stable over time while resisting fracture, cracking, or warping under stress. The result is a splint that provides strong, long-lasting protection for patients with grinding habits, TMJ dysfunction, or athletic needs.

One of the greatest advantages of SplintSmile Hard is its ability to deliver same-day or next-day appliances. With a print time of just 45 minutes, clinics and labs can produce chairside or on-demand nightguards and mouthguards without delays. This rapid turnaround increases patient satisfaction, optimizes scheduling, and reduces reliance on outsourcing.

Designed with workflow efficiency in mind, SplintSmile Hard is compatible with a range of open-system 3D printers, including ASIGA, Phrozen, and Anycubic. Its broad printer compatibility allows both small clinics and large-scale labs to adopt the material without the burden of expensive, proprietary hardware. Additionally, each 1 kg bottle yields up to 65 printed splints, providing strong ROI and reliable cost control.

Post-processing is simplified for technicians. The resin is easy to clean, polish, and cure, resulting in a glossy, smooth finish that enhances comfort and esthetics. Unlike many traditional materials, SplintSmile Hard is completely odor-free, creating a pleasant lab environment and a more comfortable experience for patients during fittings or adjustments.

Clinicians benefit from a resin that offers predictable handling and high surface accuracy. Appliances printed with SplintSmile Hard demonstrate consistent margins, snug intraoral fit, and stability across extended use. This precision minimizes chair time for adjustments and ensures appliances perform as intended with minimal follow-up.

For dental professionals, SplintSmile Hard presents a superior solution to traditional thermoformed guards or milled splints. It reduces material waste, eliminates manual labor steps, and allows full customization of appliance shape, thickness, and contact zones through CAD/CAM design. This digital flexibility enables more precise targeting of patient-specific occlusal patterns.

SplintSmile Hard is ideal for managing bruxism, TMJ issues, preventive care in athletes, or post-orthodontic stabilization, making it a staple material for restorative, general, and sports-focused dental practices. Its high durability also makes it suitable for long-term use, giving patients peace of mind and reliable performance across months of nightly wear.

As part of the broader Smile lineup, SplintSmile Hard reflects C.E.I.B.med’s core philosophy: to innovate dental materials that balance clinical excellence, workflow optimization, and patient satisfaction. Whether integrated into an in-house digital workflow or mass-produced in a lab environment, this resin empowers dental professionals to provide customized, top-tier protective devices quickly and efficiently.

SplintSmile Hard delivers professional-grade durability, precision fit, and production speed—making it the definitive solution for long-lasting occlusal protection in modern digital dentistry.
