AuPtPdAg 87,2—8,8–1,3—0,4

Manufacturer:
«Vital-Е», Ltd. Yekaterinburg. The enterprise is registered in the Russian Federation and entered on the State Register of Medical Articles. The alloy is certified with the Registration Certificate issued by the Federal Agency for the supervision control in the field of health care and social development #ФС 01012005/2639—05.

Subject to the classification, NIMO is referred to type ‘A dental alloys — gold-platinum-palladium;
Meets the requirements of ISO 9693:1991 (Е);
Disenfection-resistant subject to the requirements of МУ 287—113;
Passed toxicological, sanitary and chemical and biological tests;
The Certificate of Conformance #319—05 from 01.08.2005 issued by VNIIMT:
- «The alloy is non-toxic and meets the requirements of the normative documentation»
Composed and confirmed by Ministry of Health, TR 9391—001–16626753—2005;
The alloy passed medical tests;
The Certificate of Conformance issued by the Central dental care of the Federal Administration of medical and biological and extreme problems of Ministry of Health of Russia:
- «The alloy meets modern requirements of medical practice, is of good quality, responds to medical purpose».

Advantages:

good casting properties;
corrosion resistance;
effective cohesion with porcelain and plastic;
biocompatibility with human tissues;
closer contact;
gives a more pleasant tint to ceramics;
design corresponds to natural teeth;
causes no marginal gingival darkening

«VitIrium» is intended for production of dentures using lost-wax casting method: dental crowns, portion crowns, inlays, metal insert teeth, lugs and bridges with ceramic-coating. The alloy is produced in the form of 2.0mm-thick, 10mm-wide, 10mm-long strips. The weight of one strip amounts to 3.6—3.8 g.
