Redefining jawbone reconstruction

A custom graft
built for every
mandible

So patients look like themselves again

Who we are

Scientists from Dartmouth Engineering building a solution for patients, surgeons, and hospitals.

GyroGel was founded to bring bone graft technology out of the research lab and into the OR to improve the standard of care.

What we do

Bio-ceramic gyroids 3D printed
with polymer cryogel composite.  

We regenerate bone by combining mineral 3D printing with biodegradable, porous, and FDA-approved organic material that mimics cancellous bone morphology.

The standard of care for maxillofacial tumor treatment is costly, complicated, and diminishes quality of life.

Head and neck cancer is the 7th most common cancer in the world. In the US, approximately 55,000+ cases of oral cancer are diagnosed annually,

27 – 50% of those patients experience mandibular invasion that necessitates bone resection and subsequent reconstruction.

GyroGel could reduce the costs of mandibular reconstruction by 52%

The materials we're developing seem to act like a shield, such that if you remove a tumor, implant this scaffold, and then deliver radiation, you see less of that damaging aging effect.
