The technology omits the stage of making the prototype and thus cuts down the implant manufacturing to a single stage only. 
The experts of the Tomsk State University have developed a direct method of printing implants for lost bone fragments to speed up their production and make them more accessible to patients. The TSU press service reported to TASS on the subject.
"At present, it takes a lot of time to make a construction for compensating defects of bone tissue. Material scientists are now developing a direct method of printing new generation implants. That implies eliminating the stage of prototype manufacture, which will make it possible to produce an implant in one stage”, - the press service said.
The laboratory including specialists from the Tomsk Oncology Research Institute and the Durability Physics Institute of the Russian Academy of Sciences as well is now also engaged in the modification of the material for these prostheses. The researchers are working on a new project that will turn the artificial material as equivalent to the natural bone as possible, which will in turn improve the implants success and enhance the patients' chances of recovery. "Presently the nanoceramics from which the implants are composed have pores of 20 to 30 microns in size. Researchers are developing a new approach that will provide ... a bimodal structure with pores of two sizes - 30 and 300 microns. That will maximally assimilate implants to the natural bone and improve their fusion with the patient's natural tissue,” - the university said.
In the summer of 2017, the Tomsk Oncology Research Institute carried out Russia’s first ever surgery on closing a facial bone tissue defect with an implant of porous nanoceramics. The surgery was performed on a 26-year-old patient who had lost part of the upper jaw due to osteogenic sarcoma. As the press service of the TSU reports, afterwards the girl underwent a follow-up examination, which showed that the body adopted the implant to organically coexist with the patient's natural tissues.
