BUILDING BETTER BONES WITH 3-D PRINTING

The video discusses the challenges of traditional bone implants, especially in children, and introduces a new 3D printed synthetic bone implant developed by Northwestern University. This biomaterial, made from hydroxyapatite and a biodegradable polymer, promotes bone regeneration and can be customized for patients. The 3D printing process allows for rapid production and the incorporation of additional substances like antibiotics. The video also includes a humorous segment about skull size and bone implants.

What is a potential issue with permanent bone implants in children?

• They are not effective in adults.

• They are too expensive.

• They cause immediate pain.

• They require frequent replacement surgeries.

What innovative material have researchers at Northwestern University developed?

• A biodegradable plastic for bone repair.

• A new surgical tool for bone surgery.

• A 3D printable ink for synthetic bone implants.

• A new type of metal for bone implants.

What is the main component of the 3D printed biomaterial?

• Titanium and stainless steel.

• Hydroxyapatite and a biodegradable polymer.

• Silicon and carbon fiber.

• Copper and aluminum.

How does the 3D printed biomaterial aid in tissue regeneration?

• By being completely solid.

• By being highly porous at multiple levels.

• By being non-porous.

• By being liquid at room temperature.

What is a significant advantage of the 3D printed bone implants over traditional methods?

• They are less durable.

• They can be customized to the patient quickly.

• They require more time to produce.

• They are more expensive.
