CS245506B1 - Alloy for implants in dentistry and traumatology - Google Patents

Abstract

Solution aa concerns an alloy for implants in dentistry and traumatology. The essence of the alloy is that it contains 0.001 to 0.05 wt. % carbon, 1 to 8 wt. % manganese, 0.15 to 1.5 wt. % silicon, 8 to 25 wt. % chromium, 45 to 83 wt. % nickel, 5 to 11 wt. % aluminum, 0.5 to 7 wt. % molybdenum, 0.3 to 5 wt. % cobalt and 0.01 to 2 wt. % iron. The alloy has the ability to chemically bond with ceramics — dental porcelain. This eliminates electrical conductivity, and the implant becomes more resistant to corrosive environments of the oral cavity. The possibility of tissue inflammation is minimal.

Description

The solution relates to an alloy for implants in dentistry and traumatology.

The essence of the alloy is that it contains 0.001 to 0.05 wt. % carbon, 1 to 8 wt. % manganese, 0.15 to 1.5 wt. % silicon, 8 to 25 wt. % chromium, 45 to 83 wt. % nickel, 5 to 11 wt. % aluminum, 0.5 to 7% by weight; % molybdenum, 0.3 to 5 wt. % cobalt and 0.01 to 2 wt. irons.

The alloy has the ability to chemically bond with ceramic - dental porcelain. This removes the electrical conductivity, making the implant more resistant to the corrosive environment of the oral cavity. The possibility of tissue inflammation is minimal. 245506 3 4 245506

The invention relates to an alloy for implants in somatology and traumatology.

Barbed forms of metal implants made of high-alloy alloys have found widespread use in traumatology but also in dental prosthetics. At present, the most suitable metallic material for implants is titanium, tantalum. Their disadvantage is the conductivity of the electric current and the fact that they often cause inflammation. In addition, they have yet another disadvantage - the inability of long-term natural mechanical attachment to bone tissue. '

Jacobs and Kirch prepared an alloy of precious metal, covered with a porcelain layer to form an insulating layer between the bone tissue of the mucoperist and the metal. In the same way, Kirchner's attempts to achieve a closer connection between bone and implant also go away.

However, alloys prepared so far do not have the property of chemical compounding with ceramic, which is a major drawback of existing implants.

This disadvantage is substantially eliminated by the alloy according to the invention, which consists in containing from 0.001 to 0.05% by weight of the composition. % carbon, 1 to 8 wt. % manganese, 0.15 to 1.5 wt. % silicon, 8 to 25 wt. of chromium, 45 to 83% by weight; % nickel, 5 to 11 wt. % aluminum, 0.5 to 7% by weight; % molybdenum, 0.3 to 5 wt. cobalt and 0.01 to 2% iron.

The alloy of the invention has the ability to chemically associate with ceramics - dental porcelain. This removes the electrical conductivity, making the implant more resistant to the corrosive environment of the oral cavity. The possibility of tissue inflammation is minimal. Example 1

0.01 g of C, 1 g of Mn, 0.3 g of Si, 20 g of Cr, 84.7 g of Ni, 9 g of Al, 3 g of Mo, 1 g of Co, 0.99 g of Fe are added to the crucible. The crucible is then placed in an oven where the components are melted. The molten mixture is cooled in a discharged furnace.
