Description
본발명은 치과용 보철합금에 관한 것으로, 보다 상세하게는 여러 종류의 재료를 함께 용융하여 제조된 표면이 황금색을 띄는 치과용 보철합금에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental prosthetic alloy, and more particularly, to a dental prosthetic alloy in which a surface produced by melting various kinds of materials together is golden.
일반적으로 등록특허공보 등록번호 10-0329822호에 종래기술로 기재된 바와 같이, 치과용 합금은 온도, 산도, 압력변화 등의 다양한 환경변화가 일어나는 구강내에서 사용되기 때문에 첫째로, 씹는 압력에 견딜 수 있어야 하고 마모, 변형 등이 없어야 하며, 치아의 경도 강도와 비슷해야 하고 치아색과 유사해야 한다. 또한 구강내에서 부식이나 변색 등이 없어야 하며 인체 유해성이 없어야 한다. 이와 같은 관점에서 융점이 비교적 낮고 주조성이 우수하며 공기중에서도 산화가 발생하지 않는 75% 이상의 금 함량의 합금이 널리 사용되고 있으나, 금 함량이 높은 합금은 가격이 높은 단점이 있기 때문에 기존의 금합금과 제반 성질이 유사하지만 경제성이 우수한 금대용 합금으로 저금합금 및 비귀금속합금 등이 개발되고 있다. 그러나 이들 합금은 임상실험 결과 화학적, 기계적 관점에서 금함량이 적어질수록 잦은 변색물의 발생과 파절, 세포독성의 발생, 치아 경도보다 더 강한 경도값을 갖는 등의 단점이 있다.Generally, as described in the prior art in Patent Registration No. 10-0329822, since dental alloys are used in the oral cavity where various environmental changes such as temperature, acidity, pressure change, etc. occur, firstly, There should be no wear, deformation, similar to the hardness of the teeth, and similar to tooth color. There should be no corrosion or discoloration in the oral cavity and no harmful effects on the human body. From this point of view, an alloy having a relatively low melting point, excellent castability, and a high gold content of 75% or more, which does not cause oxidation in the air, is widely used. However, since an alloy having a high gold content has a disadvantage of high price, Gold alloys that are similar in properties but excellent in economy are being developed, such as gold alloy and non-noble metal alloy. However, as a result of clinical tests, these alloys have disadvantages such as occurrence of frequent discoloration and generation of discoloration, occurrence of cytotoxicity, and hardness value which is stronger than tooth hardness as the gold content is decreased from the chemical and mechanical viewpoints.
상기 단점을 보완하여 상기 등록특허공보 등록번호 10-0329822호는 금속-자기질용 치과 귀금속 합금으로써, 금 48~55w%, 팔라디움 28~35w%, 은 2.5~4.5w%, 동 4.5~6.5w%, 인듐 3.5~5.0w%, 갈륨 1.0~4.0w%, 아연 0.5~1.5w%, 이리듐 0.05~0.2w%를 포함하는 합금으로 된 금속-자기질용 치과 귀금속 합금을 공개하고 있다.In order to compensate for the above disadvantages, the registered patent publication No. 10-0329822 discloses a dental precious metal alloy for a metal-magnetic material, which comprises 48 to 55 wt% of gold, 28 to 35 wt% of palladium, 2.5 to 4.5 wt% of silver, , 3.5 to 5.0 wt% of indium, 1.0 to 4.0 wt% of gallium, 0.5 to 1.5 wt% of zinc and 0.05 to 0.2 wt% of iridium.
또한, 등록특허공보 10-0592523호에는 금을 주성분으로 하는 치과보철용 합금조성물에 있어서, 금 100 중량부에 대하여, 백금이 1 중량부 내지 9 중량부, 은이 0.1 중량부 내지 10 중량부 그리고 주석이 0.1 중량부 내지 1 중량부로 구성된 것을 특징으로 하는 치과보철용 합금조성물이 공개되어 있다.
Also, in Patent Publication No. 10-0592523, an alloy composition for dental prosthesis comprising gold as a main component is prepared by mixing 1 part by weight to 9 parts by weight of platinum, 0.1 parts by weight to 10 parts by weight of silver, Is 0.1 part by weight to 1 part by weight based on the total weight of the dental prosthesis.
그러나 상기 종래 치과용 보철합금은 미관이 좋지 않거나 제조경비가 비싸며, 또한 강도가 약하고 내구성이 떨어지는 단점이 있었다.However, the conventional dental prosthetic alloy has a disadvantage in that it has poor aesthetic appearance, is expensive to manufacture, has a weak strength, and has poor durability.
따라서 본발명은 상기와 같은 문제점을 해결하고자 안출된 것으로서, 본발명은 표면이 황금색을 띄는 것으로, 미관이 뛰어나며, 강도가 높으며, 탄성이 좋고, 금과 황금에 비해 제조경비가 저렴한 치과용 보철합금을 제공하고자 하는 것이다.Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a dental prosthesis alloy having a gold-colored surface, excellent aesthetic appearance, high strength, good elasticity, .
본발명은 치과용 보철합금에 관한 것으로, 구리, 니켈, 팔라듐, 철, 알루미늄 및 망간으로 이루어지는 것을 특징으로 한다.The present invention relates to a dental prosthesis alloy, which is characterized by being made of copper, nickel, palladium, iron, aluminum and manganese.
따라서 본발명의 치과용 보철합금은 표면이 황금색을 띄는 것으로, 미관이 뛰어나며, 강도가 높으며, 탄성이 좋고, 금과 황금에 비해 제조경비가 저렴하다는 현저한 효과가 있다.Accordingly, the dental prosthesis alloy of the present invention has a remarkable effect that the surface is golden colored, the aesthetic appearance is excellent, the strength is high, the elasticity is good, and the production cost is less than gold and gold.
본발명은 치과용 보철합금에 관한 것으로, 구리, 니켈, 팔라듐, 철, 알루미늄 및 망간으로 이루어지는 것을 특징으로 한다.The present invention relates to a dental prosthesis alloy, which is characterized by being made of copper, nickel, palladium, iron, aluminum and manganese.
또한, 상기 치과용 보철합금의 함량비는 구리 70 ~ 80중량부에 대하여, 니켈 3 ~ 5중량부, 팔라듐 3 ~ 4중량부, 철 3 ~ 5중량부, 알루미늄 7 ~ 10 중량부, 및 망간 4 ~ 5중량부로 이루어지는 것을 특징으로 한다.
The content ratio of the dental prosthesis alloy is 3 to 5 parts by weight of nickel, 3 to 4 parts by weight of palladium, 3 to 5 parts by weight of iron, 7 to 10 parts by weight of aluminum, and manganese And 4 to 5 parts by weight.
구리, 니켈, 팔라듐, 철, 알루미늄, 망간을 고주파 용융 도가니로에 투입하되, 그 함량비는 구리 70 ~ 80중량부에 대하여, 니켈 3 ~ 5중량부, 팔라듐 3~ 4중량부, 철 3 ~ 5중량부, 알루미늄 7 ~ 10 중량부, 및 망간 4 ~ 5중량부로 한다.Wherein the content ratio of copper is from 3 to 5 parts by weight of nickel, from 3 to 4 parts by weight of palladium, from 3 to 4 parts by weight of iron, and from 3 to 5 parts by weight of copper, nickel, palladium, iron, aluminum and manganese into a high frequency melting crucible. 5 to 10 parts by weight of aluminum, and 4 to 5 parts by weight of manganese.
구리는 색상이 금과 흡사하나 금보다 저가인 것으로, 70중량부 미만이면 제조경비가 상승되며, 제조된 치과용 보철합금이 색상이 희게 되며, 80중량부를 초과하면 색상이 붉게 변색되며 물렁해진다. 니켈은 치과용 보철합금으로 치과용 보철을 제조할 시 용융상태에서 유동성을 좋게 하는 것으로, 니켈이 3중량부 미만이면 제조된 치과용 보철합금으로 치과용 보철을 제조할 시 용융상태에서 유동성이 떨어지며, 5중량부를 초과하면 탄성이 없어진다. Copper has a color similar to gold but lower than gold. When it is less than 70 parts by weight, the manufacturing cost is increased, and the prepared dental prosthesis alloy becomes whitish. When the amount exceeds 80 parts by weight, the color turns red and becomes soft. Nickel is a dental prosthetic alloy that improves fluidity in a molten state when dental prosthesis is manufactured. When nickel is less than 3 parts by weight, the manufactured dental prosthetic alloy is inferior in fluidity in a molten state when dental prosthesis is manufactured If it exceeds 5 parts by weight, elasticity is lost.
팔라듐이 제조된 치과용 보철합금으로 치과용 보철을 제조할 시 용융점을 상승시키는 것으로, 3중량부 미만이면 제조된 치과용 보철합금으로 치과용 보철을 제조할 시 용융점이 떨어져 쉽게 끓어 넘치며, 제조된 치과용 보철이 푸석푸석해지는 단점이 있다. 4중량부를 초과하면 용융점이 높아지며 사용자가 사용하기 힘들어진다. 철은 치과용 보철합금으로 치과용 보철을 제조할 시 강도를 증가시키는 것으로, 철이 3 중량부 미만이면 치과용 보철의 강도가 떨어지며, 5중량부를 초과하면 너무 단단하며 탄성이 없어진다. 알루미늄이 7중량부 미만이면 치과용 보철합금의 색상이 황금색이 되지 않고, 10중량부를 초과하면 희게 되는 단점이 있다. 망간은 기화점을 높이는 것으로, 망간이 4중량부 미만이면 기화점이 낮아져 끓으면서 타는 현상이 발생되며, 5중량부를 초과하면 깨어지기 쉽다.
The dental prosthesis is made of palladium. When the dental prosthesis is manufactured, the melting point is raised. When the dental prosthesis is less than 3 parts by weight, the dental prosthesis is manufactured. Dental prostheses have a disadvantage that they become rough. If it exceeds 4 parts by weight, the melting point becomes high and it becomes difficult for the user to use. Iron is a dental prosthetic alloy, which increases the strength when dental prosthesis is manufactured. If iron is less than 3 parts by weight, the strength of the dental prosthesis is lowered. If it exceeds 5 parts by weight, it is too hard and elasticity is lost. If the amount of aluminum is less than 7 parts by weight, the color of the dental prosthesis alloy does not become golden, and if the amount exceeds 10 parts by weight, whitening may occur. When manganese is less than 4 parts by weight, the vaporization point is lowered and boiling occurs. When the amount of manganese is more than 5 parts by weight, the manganese is easily broken.
상기와 같이 투입된 재료는 용융공정을 거치게 되며, 1000 ~ 1200℃에서 2 ~ 4시간 정도 용융한다. 온도가 1000℃ 미만일 경우 용융이 완전히 되지 않고, 1200℃를 초과하면, 과열현상이 발생하여 재료 성분이 변하게 된다. 그리고 용융시간이 2시간 미만이면 용융이 완전히 되지 않고 4시간을 초과하면, 장시간 용융에 의해 재료 성분이 변하게 되거나 제작경비가 상승된다.The thus-introduced material is subjected to a melting process, and is melted at 1000 to 1200 ° C. for about 2 to 4 hours. When the temperature is less than 1000 캜, the melting is not completed. When the temperature exceeds 1200 캜, an overheating phenomenon occurs and the material composition changes. If the melting time is less than 2 hours, the melting is not completed, and if it exceeds 4 hours, the material component is changed by long-time melting or the production cost is increased.
한편, 상기와 같이 용융공정을 거쳐 용융된 합금용액은 주형공정을 거쳐 일정한 형상을 가지게 되는데, 일정 형상의 금속 재질의 금형내부에 용융액을 붓게 된다. 상기 금속은 텅스텐등 고온에 견딜 수 있는 금속으로 만들어져, 용융액이 주입되더라도 금형이 녹거나 변하지 않게 한다. 통상 금형은 상하금형으로 이루어지며, 상하금형에 의해 이루어지는 금형홈은 원형봉 형상을 이루고 있어서 주입된 합금용액이 굳으면 원형봉형상으로 제조된다.On the other hand, the alloy solution that has been melted through the melting process as described above has a certain shape through the mold process, and the melt is poured into the metal mold having a predetermined shape. The metal is made of a metal that can withstand high temperatures, such as tungsten, so that the mold does not melt or change even if a melt is injected. Normally, the mold is composed of upper and lower molds, and the mold grooves formed by the upper and lower molds have a circular rod shape, and when the injected alloy solution is hardened, it is formed into a circular rod shape.
상기 공정에 의해 만들어지는 원형봉 형상의 합금은 압연공정을 거치게 된다.The round bar shaped alloy produced by the above process is subjected to a rolling process.
압연공정은 통상의 관용기술을 적용하면 되는 것으로, 상하롤러 사이에 전공정에서 만들어진 원형봉을 통과시키면 두께가 얇은 판재가 만들어진다.The rolling process can be carried out by a conventional technique. When a round bar made in the previous process is passed between the upper and lower rollers, a thin sheet material is produced.
상기 판재를 원하는 치수로 잘라서 의치 또는 치관용으로 제작하면 된다. 주로 사용하기 편리하게 정사각형 단면을 이루게 절단한다.The sheet material may be cut into a desired size and prepared for dentures or teeth. It is mainly cut into square cross section for convenient use.
따라서 본발명의 치과용 보철합금은 표면이 황금색을 띄는 것으로, 미관이 뛰어나며, 강도가 높으며, 탄성이 좋고, 금과 황금에 비해 제조경비가 저렴하다는 현저한 효과가 있다.Accordingly, the dental prosthesis alloy of the present invention has a remarkable effect that the surface is golden colored, the aesthetic appearance is excellent, the strength is high, the elasticity is good, and the production cost is less than gold and gold.
