In general, a normal person has 16 teeth in the maxilla (maxilla) and 16 teeth in the mandible (total 16 teeth). In total, 32 teeth are generated in the infants. .

As described above, one or more teeth may be damaged due to various oral diseases (tooth decay or periodontal disease, etc.) after the formation of the device, and in this case, it is impossible to smoothly perform pronunciation or food crushing, Which often hinders normal social life.

As a method for restoring or repairing a damaged tooth as described above, a structure using a prosthetic denture has been applied.

On the other hand, dentures that are used in the dental field are prostheses that artificially replace natural teeth and related tissues when they are defected, and can be broadly divided into total dentures and local teeth.

The dental prosthesis is a dental prosthesis that supports when one or more natural teeth are missing, that is, when the tooth itself is not defective and the supporting tissue associated with the tooth is missing, It is a prosthesis that artificially replaces defects of or tissue.

In addition, the total denture refers to an entire denture, and refers to a denture made by using various materials by an artificial method and means for a patient having no natural teeth.

In addition, the metal denture among the dentures is composed of a metal work (frame work) and an artificial tooth.

Here, the metal structure is usually cast using a dental alloy, and then the shape and surface of the metal structure are processed, polished and polished.

The metal structure may be classified into a noble metal structure such as a gold alloy and a non-noble metal structure such as a NI-CR system or a CO-CR system alloy. The metal structure may be selected .

However, the noble metal structure of the conventional metal structure as described above has a disadvantage that it has a lower metal property than that of the noble metal, requires a high material cost, increases the weight due to the increase of the specific gravity, And a short life span due to the absence of corrosion resistance.

In addition, the non-noble metal structure can not be applied to a patient who has skin allergy to non-precious metal, and the design of the clasp has a limitation of esthetics due to the color of the metal itself.
