What are bioceramics and its characteristics?

2021-08-12 Page view : 39 views

Bioceramics are a special class of advanced ceramics used in medical applications. In fact, bioceramics are chemically inert, anticorrosive, antibacterial and dimensionally stable. These characteristics make this type of ceramic a perfect material for dental and bone implants. Bioceramics are also appearing in niche applications, such as specific tools for medical procedures, or pacemakers as electrical insulators.

Bioceramics cover many materials, two of which are high-purity alumina (HPA) and zirconia-based materials.

Characteristics of bioceramics

Bioceramics appear in demanding medical applications due to their outstanding properties:

The bioceramics embedded in the body must be biocompatible. On the one hand, this material is antibacterial and chemically inert in the body. This is why HPA and zirconia bioceramics are particularly biocompatible. In addition, zirconia is known for its non-cytotoxicity, which means that it is not toxic to cells.

Bioceramics should be durable, because the life of implants in the body must be longer than that of humans. This material is dimensionally stable and corrosion resistant. Due to its excellent intrinsic hardness, it has the same excellent mechanical properties as any technical ceramics. We provide zirconia-based materials to manufacture durable bioceramic components. For dental applications, bioceramics must be aesthetically pleasing. In fact, implants are said to closely mimic the appearance of natural teeth.

Transparency and specific colors.

3D Pro is particularly suitable for dental implant applications because it combines 8% yttrium oxide (bringing transparency) with the mechanical properties of zirconia. In addition, we can add colored dopants as required to add the final color to the appearance of the final bioceramics.

Dental composites should be radiopaque so that they can be easily positioned on radiographs. These dispersions contain the smallest YbF3 nano particles on the market and have the highest usable solids content. We have also developed suspended zirconia nano particles that allow the radiopaque and enhanced mechanical properties of dental composites to be combined.

Our expertise in controlling the purity and particle size and particle size distribution of the crystalline phase of the delivered product strengthens these characteristics. In addition, we can dope our products as required to add expected mechanical properties and customized colors to your final bioceramic parts.

Synthetic teeth made of high-purity zirconia have the machinability of powders. We provide powders for bioceramics. Our powder is easily adapted to the customer’s process.
