3D Bioprinting: A New Toothy Trend

Though a relatively young concept, 3D printing has become the biggest trend of the decade–from building furniture to human body parts, it seems the possibility of a 3D-printed anything could eventually be on the market. This is because 3D printing is exponentially cheaper than using traditional machinery.

While I wouldn’t mind 3D printing an entirely brand-new wardrobe (in fact, I’d probably love it), I’ve always been somewhat of a skeptic when it comes to artificial organs. Most recently, 3D printing has been incorporated in creating blood vessels for alternative root canal treatments.

The findings are expected to have impact on root canal treatments which currently involves removing the tooth’s infected pulp and replacing it with a substance known as gutta-percha. This thermoplastic material is similar to rubber and is used to fill the inside of the tooth but cannot restore function since it removes the blood vessels.

The new approach uses pre-vascularized pulp-like tissue to promote dental pulp regeneration and allow for a better long-term treatment.

In layman’s terms, it is now possible to engineer blood vessels into extracted teeth.

Fabrication of artificial blood vessels can be a highly effective strategy for fully regenerating the function of teeth.

The dental industry holds much promise for 3D printing, although not typically on a biomedical sphere, as some see the technology as the future of crown production.

The Dubai Dental Authority plans to begin 3D printing teeth by the end of the year.
