Bioceramics

NEVZ-CERAMICS masters production of alumina and zirconia ceramic products for medicine purposes (endoprosthetics, implants, implantation systems and components thereof). With bioactive coating of nanostructured hydroxyapatite our products can be efficiently used in surgical treatment of diseases and damages  of  a human locomotor system, dentistry, and maxillofacial surgeries.

-Structural strength of porous ceramics is provided by submicron and nano-sized components of ceramics;

-Porous structure of ceramics resembles a bone tissue structure in the site of implantation;

-As chemically and corrosion stable material ceramics does not  cause any biochemical or allergic reactions in the  human body, while being completely non-toxic;

-Being stable to various aggravating effects ceramics may be repeatedly sterilized under high temperature and with use of gas  without loss in performance. Radiation sterilization is also possible.

-With it’s porous surface ceramics can be used with various  bioactive media

-Special technology for filling pores with nano-structured hydroxyapatite is a highly effective solution in clinical practice.

MATERIALS FOR LIFE

A ceramic ball and a ceramic insert  for an acetabular shell form together a  ceramic-on-ceramic bearing system for hip-joint endoprosthetics with annual wear rate of 0,001-0,002 mm. Superior tribological properties, high  hardness and low roughness of material make this system perfectly suitable for young patients. Hydroxyapatite coating with defined nano-particle sizes provides formation of a new bone tissue in the area of contact and long-lasting strong fixation of the implant inside a human body.

Product		Material	Characteristic
	Ceramic ball and ceramic insert	Nanostructured compositional high-density ceramics	Crack resistance 8 (MPa•m-1/2)
	Stem	Hydroxyapatite coated titanium	Biocompatibility

SPINAL IMPLANTS

Spinal implants (a system of cage, plate and fixture)-a unique system that does not have any ceramic analogues worldwide (a patented technology). Spinal implants are used in spine surgeries for fixation, recovery of the spine supporting function by replacement in case of spine pathology.

Products		Material	Characteristic
	cage	Nano-structured  porous compositional ceramics (Al2O3+ZrO2+hydroxyapotyte)	Porosity >20%, the structure is
	Plate	Nanostructured composition  dense ceramics (Al2O3+ZrO2)	Bioinert, radiolucent
	Screws	Nanostructured composition  dense ceramics (Al2O3+ZrO2)	Bio inert, Radio transparent

CERAMIC GRANULES TO FILL BONE DEFECTS AND VOIDS

Being simple and accessible this method can be widely used in traumatology as an instrument of complex treatment of patients with comminuted long-bone fractures to stimulate osteogenesis,  repair bone defects and prevent complications caused by infections. Granules do not contain any active components, not enter into chemical reactions, and not cause rejection.

Product		Material	Characteristic
	Ceramic  granules	Porous nanostructured composition ceramics (Al2O3)	Permeable to  biological fluids
