It is. This alloy is characterized by a high yield point, a high hardness, being able to be drilled with ordinary instrument steel, and a high-tensile oxide film that adheres well to metal substrates and ceramic coatings. Disadvantages of this alloy are low biochemical compatibility, high specific gravity, and the complexity of the technology that requires the formation of a deep vacuum. Taking into account the criteria for the selection of stomatology or dental casting alloys, the presence of titanium in its composition may improve its properties. A dental casting alloy [3] comprising Ni and Ti, each having a ratio of about 50%, was selected as a prototype for the alloy of the present invention. This prototyping alloy prosthetic device is virtually free of shrinkage and fits well on gypsum models, thus easily reducing the thickness and extent of tooth products intended for use with the prosthetic device. Also, these prosthetic devices are not susceptible to oxidation and thus increase their useful life. The disadvantages of this prototype alloy are:
Low elasticity and low biochemical compatibility. The microstructural elements of this prosthetic device are:
Affected by high levels of mechanical loading, for example, the frame of a removable partial prosthetic device is weak because it is not elastic. In order to increase the strength of this partial prosthetic device, it is necessary to increase the volume of the material and thus the mass of the prosthesis.

The result of these technical advantages is achieved by a dental casting alloy based on Ni and Ti and adding the following alloying elements or components in the following mass percentages: Ti: 40-50% Mo: 0.2-2.0% Fe: 0.1 to 1.5% Cu: 0.1 to 1.0% Co: 0.1 to 0.5% Ni: 100% remaining.

の最後の利点は、本発明の合金の低比重によって増幅される。[0008] The presence of Mo, Fe, Cu and Co elements in this Ni-Ti alloy gives superior properties different from those of its prototype. This enables the above results to be achieved. Combined research and testing on this alloy, comparative evaluation of its technical properties, characterizes its several technical and functional benefits: High fluidity. This allows the casting of removable prosthetic devices in complex and thin configurations (FIGS. 1-3), without vacuum and with a highly uniform alloy structure. Low shrinkage. This offers the technical accuracy of adapting the alloy to the dental model and the possibility of maximizing the intra-oral fit of the prosthetic device, including the supporting surfaces of the teeth. Shrinkage is essentially zero. Low melting point. As a result, the requirements for the mold material having a melting point of 1130 to 1210 ° C. and the cast solidified product are reduced. Super elastic. This term corresponds to the rubber-like behavior of the alloy when it is subjected to alternating strain loading and release. The maximum strain value of the alloy according to the invention, which returns after unloading, reaches up to 2.5% and may correspond to the elasticity of living tissue. This agreement (in terms of strain properties) minimizes and virtually eliminates macro substitution and overload at the "alloy-tissue" interface. This elastic nature also reduces the prosthesis from breaking around the tissue, including breaks caused by repeated loading. This elasticity reduces the volume of the alloy required to perform its function, and thus reduces the mass of the prosthetic device. This last advantage is amplified by the low specific gravity of the alloy according to the invention.

の残りによる支持によって鋳造補綴デバイスが施された。 部分補綴デバイスの良い保持が達成され、かつ咀嚼時の普通の機能が回復され
た。肯定的な結果が９カ月にわたって実証された。Using the method of induction centrifugal casting, the prepared alloy was poured into a unitary cast removable prosthetic device or mold having a so-called “clammers” of T-type. After anti-inflammatory treatment of periodontal treatment, the tooth with a mobility of III (advanced mobility) was extracted. 3 teeth, Equation 4, 2⊥5 (with II mobility and 1/3 root bone loss)
The cast prosthetic device was applied by support from the rest of the. Good retention of the partial prosthetic device has been achieved and normal function during mastication has been restored. Positive results have been demonstrated over nine months.
