Researchers Believes 3d Printed Teeth Regrowing Required 3d Printing

Auto Draft

3D printing, a relatively new manufacturing method, allows for small batches of highly customized items. This technology can also create products from biological materials that are biocompatible to humans. 3D printing is a popular tool in medicine. This technology is used in dentistry to replace missing or damaged teeth. However, researchers at KU Leuven University are now looking beyond replacing 3d printed teeth and toward regeneration and regrowth. They use 3D printing to repair the root of damaged teeth.

Form of Additive Manufacturing

Instead of subtractive manufacturing where the material is removed to create final products, like carving an item out of a large block, 3D printing, which is a form of additive manufacturing, involves gradually adding material until the product is complete. The 3D printer is composed of a nozzle, extruder, and motor that can freely move across the x-, y-, and z planes. The printer works by recreating a Computer-Aided Design model (CAD). The material filament is fed through the extruder to the nozzle. This then creates the product on the print bed. This manufacturing process is completed layer by layer and built upon itself in small increments.

Additive manufacturing has the most obvious benefit: it reduces waste. It is easy to recycle the waste produced by additive manufacturing. A CAD drawing can also be used to create a 3D printed product. It is possible to create a product without the need for molds and stamps like in subtractive manufacturing. There are also no switching costs when changing tools, such as drill bits. However, additive manufacturing has its disadvantages. 3D printing can be cheaper for small quantities of products or complex structures, but it is slower and more expensive than subtractive manufacturing methods when producing large quantities. 3D-printed products have a rough finish because the layers of additive manufacturing material leave ridges throughout the entire body. To give 3D-printed products a smooth finish, subtractive manufacturing may be necessary.

Because 3D printing can be used to create small batches of complex and unique structures, it is becoming more popular in the regenerative medicine industry. This method is capable of producing highly customized pieces that are made for each patient while remaining cost-effective. 3D printing is able to produce biocompatible components. 3D Bioprinting, which is a process of manufacturing with bioink, is a material made from biological material. Bioprinting is being investigated for its potential applications in bone fracture treatment and fully 3D-printed human bodies. The technology can also be used to reshape human teeth cells.

Innovation In Regenerative Dentistry

Researchers at KU Leuven University discovered new innovations in 3D Bioprinting and a focus on tissue repair and regrowth, also known as regenerative dentistry. Researchers at KU Leuven University observed the effects of compromised dentin-pulp combinations on tooth growth. Research has shown that dental pulp can be damaged by trauma or teeth with developmental issues. This pulp is responsible for the formation of dentin (the less brittle material that supports tooth enamel) and houses the majority of the nerves. Pulp necrosis can occur in severely damaged teeth and may prevent tooth growth. These situations can lead to the loss of tooth tissue or the complete tooth. Researchers are now exploring the possibility of restoring damaged dentin-pulp structures using 3D-printed scaffolding made from chitosan. This will allow the root to heal and regrowth the damaged tooth if it is done correctly.

Chitosan

It is the biomaterial that was used to make the tooth root scaffolding. This material is made from exoskeletons, primarily of crustaceans and fungi. This material is biocompatible and has antimicrobial qualities. It is less likely that chitosan derived from fungi will cause allergic reactions. These chitosan scaffolds were made using 3D printing, CAD, and freeze-drying manufacturing methods. These molds can be modified to fit the needs of specific teeth or the anatomy of the patient. The scaffolds have been installed and are currently being observed. If the experiment is successful, the compromised pulp won’t reject the scaffolding and the immune system will respond accordingly. Monitoring will be done to monitor stem cell growth.
