The knowledge-based company Salamatsazan Hedayat has developed high-performance nano-zirconia dental blocks that improve the quality and biocompatibility of dental reconstruction and implant procedures. These blocks, made from nano-structured zirconia ceramics, combine superior mechanical strength, long-term durability, and natural esthetics, enabling the production of abutments and permanent dental prostheses.

After more than five years of dedicated research and development, the company successfully localized the technology for producing zirconia blocks from nano-zirconia powder. Following a precise sintering process, the material achieves exceptional physical, chemical, and biological properties. Designed to replace lost hard oral tissues such as enamel and dentin, the blocks are now used as long-lasting dental prosthetic components.
According to the CEO of the company, these zirconia blocks are suitable not only for dental crowns and bridges but also for implant abutments and suprastructures. In specialized cases, they can even simulate structures that replace parts of bone or gum tissue without direct bone contact — a unique feature that distinguishes them from many traditional dental materials.
The company’s zirconia discs and blocks have passed all international standard tests under ISO 6872:2015 for dental ceramics, and have obtained ISO 13485:2016 certification along with a manufacturing license (No. 54263709) from Iran’s Food and Drug Administration. These products rival their European counterparts in both quality and aesthetics and have been validated by professional dental specialists.
The use of high-purity nano-zirconia ceramics enhances the blocks’ strength, optical translucency, and biocompatibility, ensuring excellent integration with the human body. Fully compatible with digital CAD/CAM milling systems, they allow dental laboratories to design highly precise, natural-looking restorations.
With a multidisciplinary team of experts in ceramic engineering, chemistry, mechanics, and dentistry, and equipped with an advanced digital laboratory, Salamatsazan Badih Hedayat is paving the way for the domestic production of advanced, nano-structured dental materials, marking a major step toward technological self-reliance in Iran’s dental industry.
