Description

치과재료용 금-은-파라디움(Au-Ag-Pd)계 합금Gold-Silver-Paradium (Au-Ag-Pd) Alloys for Dental Materials

본 발명은 금-은-파라디움(Au-Ag-Pd)계 합금에 관한 것으로 내식성이 높고 변색이 없으며, 주조성, 가공성이 우수하여 치과용 재료로서 적합하다.The present invention relates to a gold-silver-paradium (Au-Ag-Pd) -based alloy, which has high corrosion resistance, no discoloration, excellent castability and processability, and is suitable as a dental material.

본 발명의 합금은 종래의 치과용-장식용 금 합금보다 금의 함량을 50% 이하의 소량으로서 제조하는 합금으로 치과용 금 합금에서는 다량의 금이 함유되어 있으면서도 동(銅)이 함유한 까닭에 구강내에서 변색이 종종 일어나며 재사용을 할때는신품(新品)을 동량(同量)이상으로 제혼합하여야 사용이 가능하였다.The alloy of the present invention is an alloy which is produced in a smaller amount of gold than 50% of the conventional dental-decorative gold alloys, and dental gold alloys contain a large amount of gold while the copper is contained in the oral cavity. Discoloration often occurs in the interior, and when it is reused, new products must be mixed and mixed in the same amount or more.

장식용에서도 다량의 금 합량의 소요로 인한 제품의 원가상으로 특별한 고가품 의에는 제조할 수가 없었다.Even for decorative purposes, due to the high cost of the product due to the large amount of gold, it was not possible to manufacture a special expensive product.

종래의 금 합금에 대표적인 것으로는 Au-Cu계 합금Au-Ag-Cu계 합금, Au-Ni-Cu-Zn계 합금으로서 금(Au)의 함량에 따라 10k,12k,14k,18k등이 있고, Au-Pt계 합금, Au-Cu계 합금이 있으며, 이외에도 다음과 같은 금 합금이 알려져 있다.Typical gold alloys include Au-Cu-based alloys Au-Ag-Cu-based alloys and Au-Ni-Cu-Zn-based alloys, such as 10k, 12k, 14k, and 18k, depending on the content of gold (Au). There are Au-Pt-based alloys and Au-Cu-based alloys. In addition, the following gold alloys are known.

본 발명은 은(銀)을 주성분으로 하여 종래의 금합금보다 50% 이하의 금 함량으로서도 종래의 1k부터 16k까지의 금 합금과 각각 동등한 색상을 나타내며 변색이 없고 내식성, 주조성 및 경도와 강도가 치과용으로 적합한 합금으로서 동이 함유되어 있지 않으므로 변질, 변색이 없으며 일차 사용한 것을 신품과 혼합하지 않고 그대로 제사용하여도 신품과 차이가 없다.The present invention is composed of silver (주) as the main component of the gold content of 50% or less than the conventional gold alloy, each of the same color as the conventional gold alloys from 1k to 16k, respectively, without discoloration, corrosion resistance, castability and hardness and strength is dental It is an alloy suitable for use and contains no copper, so there is no alteration or discoloration, and even if it is used as it is without mixing with a new one, there is no difference from a new one.

본 발명의 치과용 합금의 성분은 은(Ag)을 주성분으로한 파라디움(Pd), 금(Au), 인디움(In),아연(Zn)의 합금으로서 구체적인 조성은 다음과 같다.The component of the dental alloy of the present invention is an alloy of palladium (Pd), gold (Au), indium (In), and zinc (Zn) mainly composed of silver (Ag).

인디움(In)-12-19, 은(Ag)36-49%, 금(Au) 3-29%, 파라디움(Pd)17-26%, 아연(Zn)4-7%로 구성되어 있다.It is composed of indium (In) -12-19, silver (Ag) 36-49%, gold (Au) 3-29%, paradium (Pd) 17-26%, and zinc (Zn) 4-7%.

이와 같이 본 발명 구성 원소의 한정 이유는 다음과 같다.Thus, the reason for limitation of the structural element of this invention is as follows.

은(Ag)은 줄이고 인디움(In) 및 아연(Zn)의 함량을 늘리면 내식성이 감소하여 변색이 용이하며 경도 및 강도가 감소한다.If silver (Ag) is reduced and the content of indium (In) and zinc (Zn) is increased, the corrosion resistance is reduced, so that discoloration is easy and hardness and strength are reduced.

또한, 은(Ag)은 함량이 49%를 넘으면 역시 내식성이 감소하고, 36%이하이면 이디움(In)과 아연(Zn)의 합금 작용에서 나타나는 황금색도가 엷어지며 강도 역시 감소한다.In addition, if the content of silver (Ag) exceeds 49%, the corrosion resistance also decreases. If the content of silver (Ag) is less than 36%, the golden color of the alloying action of dium (In) and zinc (Zn) becomes thin and the strength also decreases.

아연(Zn)이 7%를 넘으면 경도 및 강도가 감소하고 합금의 색상에 적색 성분이 나타나며 반대로 4%이하이면 은(Ag)과 인디움(In)과의 합금 작용에서 나타나는 항금색도가 박약해지고 유동성이 떨어져 주조가 어렵게 된다.If zinc (Zn) is over 7%, hardness and strength decreases, and red color appears in the color of the alloy. On the contrary, if less than 4%, the anti-gold color of alloying with silver (Ag) and indium (In) is weakened. Poor fluidity makes casting difficult.

인디움(In)은 19%를 넘으면 경도 및 강도가 감소되어 주조한 치관(齒冠)의 얇은 부위가 파절(破折)되는 결함이 생기며, 반대로 12%이하이면 경도 및 강도는 다소 증가하나 은(Ag)과의 합금작용에서 나타나는 황금색도가 감소된다.Indium (In) is more than 19% in hardness and strength decreases, so that the thin portion of the cast crown fractured, the defect is broken, whereas less than 12% is slightly increased in hardness and strength The gold color of alloying with (Ag) is reduced.

금(Au) 이 29%를 넘으면 증가한만큼 황금색도는 높아지나 경도 및 강도가 감소될뿐아니라 코스트가 높아지므로 본 발명의 목적을 달성할 수 없으며 반대로 3%이하일때에는 인디움(In)합금에서 생성되는 황금색상이 나타나지 않는다.When gold (Au) exceeds 29%, the golden color increases as it increases, but not only hardness and strength decrease, but also the cost increases, so that the object of the present invention cannot be achieved, and when it is 3% or less, it is formed from indium (In) alloy. The golden color does not appear.

파라디움(Pd)은 26%를 넘으면 경도 및 강도는 향상되나 단가가 높아지고 금(Au)과 인디움(In) 은(Ag)과 아연(Zn)의 합금 작용에서 나타나는 황금색도를 상쇄시키고, 반대로 17%이하이면 내식성과 인장강도가 저하된다.If Pd is over 26%, hardness and strength will be improved, but the unit price will be increased, and the gold color will be offset by the alloying effect of gold (Au) and indium (In) silver (Ag) and zinc (Zn). Below% will lower the corrosion resistance and tensile strength.

따라서 본 발명에서 미황금색(2k)의 황금색상, 적당한 인장 강도 및 내식성을 갖게 하려면 금(Au) 4% 파라디움(Pd) 25%가 적당하고, 12k의 황금색상을 갖게 하면서 적합한 경도 및 강도와 색상 및 내식성을 갖게 하려면 금(Au) 18%, 파라디움(Pd) 21%의 합금을 권장할 수 있고, 보편적으로 저가의 코스트와 적합한 경도 및 강도, 내식성 및 색상을 갖게 하려면 금(Au) 3-29% 파라디움(Pd) 17-26% 합금을 권장할 수 있다.Therefore, in the present invention, in order to have a pale yellow color (2k) golden color, moderate tensile strength and corrosion resistance, gold (Au) 4% palladium (Pd) 25% is suitable, while having a golden color of 12k, suitable hardness, strength and color And alloys of 18% gold (Au) and 21% palladium (Pd) may be recommended for corrosion resistance, and gold (Au) 3-29 for universally low cost and suitable hardness and strength, corrosion resistance and color. % Paradium (Pd) 17-26% alloys may be recommended.

본 발명의 금-은-파라디움(Au-Ag-Pd)계 합금은 종래의 고간인 금 합금을 대체 사용할 수 있는 치과용 재료 합금으로서, 치과용 금 합금으로 널리 쓰이는 미국 A.D.A.S type(Ⅰ)(Ⅱ)(Ⅲ)에 버금가는 내식성, 주조성, 가공성이 우수한 특성을 지니고 있으며 동(銅)을 함유하지 않으므로구강 내에서 변색이 전혀 없어 치관용으로 적합하다.The gold-silver-paradium (Au-Ag-Pd) -based alloy of the present invention is a dental material alloy that can replace the conventional ganese gold alloy, and is widely used in the US ADAS type (I) (II) (II). Corrosion, casting, and processability comparable to those of (III) are excellent. It does not contain copper, so there is no discoloration in the oral cavity.

본 발명은 치과용 재료 합금에 국한하는 것은 아니며 고가의 미술 조각품, 장식품 제조용 금 합금에 대체 합금으로서도 유용한 것이다.The present invention is not limited to dental material alloys and is also useful as an alternative alloy to expensive art sculptures and gold alloys for making ornaments.
