Graphy Launches Dental Crown Material That Cuts Post-Processing

A new dental resin eliminates the trimming step for 3D-printed prosthetics

South Korean materials company Graphy Inc. has introduced Tera Harz E-Enamel, a 3D-printing resin for permanent dental restorations that requires no cutting or grinding after the print finishes. The company secured South Korean manufacturing certification on September 7 and has submitted a 510(k) premarket notification to the U.S. Food and Drug Administration.

The material contains 53 percent inorganic ceramic filler in a polymer matrix. It is designed to produce crowns, bridges, inlays, and onlays directly from digital design files. Conventional zirconia restorations still require milling from blocks or discs followed by sintering. Graphy says its process skips both steps.

Graphy is not new to 3D-printed dental products. The company already sells SMA, a shape-memory clear aligner made with photopolymer materials. The new product expands that photopolymer expertise into aesthetic prosthetics. The company plans to supply 3D printers, post-processing equipment, and training alongside the resin.

Graphy CEO Shim Un-seop said the product extends the company's accumulated technology from orthodontics into the prosthetics market. The company is also pursuing a partnership with Megagen Implant to connect implant treatment with prosthetic fabrication.

The U.S. market is the next target. Graphy aims to obtain FDA clearance by the fourth quarter of 2026. If approved, the material would join a small but growing list of FDA-cleared dental 3D-printing resins for permanent restorations.
