Dental Biomaterials & Bioengineering

Dental biomaterials and bioengineering are critical fields within dentistry that focus on the development and application of materials used for dental restorations, prosthetics, and regenerative treatments. These areas combine principles from materials science, biology, and engineering to create solutions that enhance oral health and functionality.

Key Concepts in Dental Biomaterials & Bioengineering:

• Biocompatibility: The ability of a material to perform with an appropriate host response when applied to the body.
• Durability: Materials must withstand the mechanical stresses of the oral environment.
• Innovative Applications: Integration of advanced technologies for improved dental care.
