Intended Use

FREEPRINT® crown is indicated as an indirect restorative for both anterior and posterior restorations, including occlusal surfaces. The FREEPRINT® crown material is used for fabricating temporary or permanent restorations such as crowns and bridges, inlays, onlays, veneers and full crown restorations. Fabrication of FREEPRINT® crown requires a computer-aided and manufacturing (CAD/CAM) system that includes the following: scanner, design software, additive printer, and post-cure unit.

Device Story

FREEPRINT® crown is a light-cured, methacrylate-based resin for 3D printing dental restorations. Dental technicians use CAD software to design restorations from digital scans, generating STL files for additive manufacturing. The workflow requires a validated 3D printer and post-cure unit. The device is used to produce temporary or permanent crowns, bridges, inlays, onlays, and veneers. By providing a biocompatible, shade-matched material, it enables precise, custom-fit dental prosthetics. The final restoration is a one-time use, prescription-only device. The resin's physical and chemical properties allow for durable, aesthetic dental replacements, benefiting patients by restoring tooth function and appearance.

Clinical Evidence

No clinical or animal testing data included. Performance established through non-clinical bench testing, including physical property testing per ISO 4049:2019 and ISO 10477:2018, and biocompatibility evaluation per ISO 10993 series and ISO 7405:2014.

Technological Characteristics

Methacrylate-based polymer resin (includes dimethacrylate). Curing via 385 nm visible light plus post-curing. Non-sterile. Available in VITA-shades. Requires validated 3D printer and post-cure unit. Complies with ISO 4049:2019 and ISO 10477:2018 for flexural strength (≥100 MPa), water sorption (≤40 µg/mm³), and water solubility (≤7.5 µg/mm³).

Indications for Use

Indicated for patients requiring temporary or permanent indirect dental restorations, including crowns, bridges, inlays, onlays, and veneers for anterior and posterior teeth, including occlusal surfaces.
