The wisdom accumulated by Hanri Medical’s R&D team is fully embodied in our extensive intellectual property portfolio and market-leading product performance. Adhering to the innovation strategy of "developing one batch, reserving one batch and launching one batch", the Company has obtained a total of 12 national Utility Model Patents to date, with another 3 Invention Patents under substantive examination.
These 15 patented technologies are not merely theoretical concepts on paper. Instead, they are deeply integrated into the design and manufacturing process of every single dental tungsten steel bur and grinding head, forming a solid technological moat for the enterprise.

In our core product lines — dental tungsten steel burs and tungsten steel grinding heads — our patented technologies cover full-chain innovations ranging from raw material welding and intelligent processing clusters to quality control. Such technologies greatly improve the wear resistance and fracture resistance of burs, extending their clinical service life by over 30% compared with competing products.
Meanwhile, Hanri’s products deliver finer cutting and grinding performance, substantially reducing damage to healthy dental tissues, which fully embodies the minimally invasive philosophy and humanistic care of modern stomatology. Thanks to these technological breakthroughs, Hanri burs have reached internationally advanced standards in core indicators including cutting efficiency, concentricity and runout precision.
From 12 granted patents and 3 pending invention patents, to annual R&D investment exceeding RMB 2 million and successful execution of provincial and municipal scientific research projects, Hanri Medical has built a three-dimensional innovation system supported by patents as individual breakthroughs, processes as connecting links and products as comprehensive carriers. Every bur and grinding head rolling off our production lines incorporates these cutting-edge technological achievements.
Moving forward, relying on our robust R&D team and sustained innovation investment, we will keep developing more efficient, precise and safe rotary instrument solutions for dental practitioners worldwide.
