Vacuum machine for deposition (applying) vacuum coatings on dental crowns and prostheses are made with ion sources. This makes it possible to reduce the process temperature (to apply coatings on various materials), improve adhesion, gloss, uniformity and increase the microhardness of the coating.
Vacuum equipment allows applying protective-decorative, hardening coatings (nitrides, carbides, carbonitrides, oxides) on small tools, dentures, crowns and obtaining surfaces of various colors. Vacuum coating equipment for deposition dental crowns and prostheses can operate in manual, semi-automatic and automatic modes. It is controlled from a personal computer based on Siemens and Advantech controllers.
To prepare the surface of stainless steel crowns and prostheses, we manufacture EPP electrolytic plasma polishing machine, which improve the surface to 3 classes - polish to a mirror finish. This greatly improves the quality of the vacuum coating.
As a result of the work carried out in all the republics of the former USSR, more than 65 areas for applying coatings of titanium nitride ((TiN) and zirconium nitride (ZrN) on dental crowns were organized in dental clinics. In other words, clinics were equipped with devices for spraying dental crowns and prostheses. In this case, only titanium and vacuum-melted zirconium were used as the cathode.
The Commission of the Ministry of Health of the USSR agreed on the technical specifications for these coatings and approved the chief dentist of the USSR Leontiev. For a cycle of work on the introduction of technology and equipment into medical practice in 1986, a group of specialists was awarded the State award of the Republic of Belarus.
