본 발명은 치과용 보철에 관한 것으로서, 특히 각종 구강질환의 발병을 강력히 억제할 수 있고, 그 작용을 장기 지속시킬 수 있도록 한 나노실버(nano silver)가 함유된 치과용 보철에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to dental prostheses, and more particularly, to dental prostheses containing nano silver, which can strongly suppress the onset of various oral diseases and allow the action to last for a long time.

치과용 보철은 풍치나 충치, 또는 사고로 인한 외상 따위의 요인으로 상실되 거나 손상된 치아를 치료하여 상실된 저작(咀嚼)기능이나 심미 등을 회복시켜 주는 치아 대체물로서, 신경치료 등으로 약해진 치아를 감싸거나 치아의 상실 부위를 수복하는 일반 보철, 변색ㆍ형태 이상ㆍ틈새 등을 개선하는 심미 보철, 도 1과 같이 치아가 상실된 치조골에 인공치근을 심어 유착시킨 뒤 여기에 인공치아를 고정하는 임플란트(implant) 등이 있다.Dental prosthetics is a tooth substitute that restores lost chewing function or aesthetics by treating lost or damaged teeth due to trauma, tooth decay, or accidental trauma. Ordinary prosthetics to repair the site of loss or tooth loss, esthetic prosthesis to improve discoloration, shape abnormalities, gaps, etc. ).

상기와 같은 치과용 보철은 인장강도ㆍ탄성률ㆍ내마모성ㆍ피로강도 등 기계적 성질이 양호해야 하고, 타액 등에 의한 부식작용에 충분히 견딜 수 있도록 내식성이 우수해야 하며, 독성ㆍ발암성ㆍ부작용 등 시술 후 인체에 거부반응이 전혀 없어야 한다.The dental prosthesis as described above should have good mechanical properties such as tensile strength, elastic modulus, abrasion resistance and fatigue strength, and have excellent corrosion resistance to withstand the corrosive action by saliva. There should be no rejection.

이러한 요건들을 고려할 때 치과용 보철로써 적합한 재료로는 스테인리스강, 코발트(Co/cobalt)합금, 티탄(Ti/titanium), 티탄합금 등이 있다. 특히 티탄합금의 경우, 스테인리스강이나 코발트합금에 비하여 밀도가 낮고 기계적 성질과 내식성이 우수함에도 불구하고 높은 용융점에 의한 가공의 어려움으로 한때 제한적으로 사용되었으나, 최근 가공기술 발달로 치과용 보철분야에서 크게 각광을 받고 있는 재료이다.Given these requirements, suitable materials for dental prostheses include stainless steel, co / cobalt alloys, titanium / titanium, and titanium alloys. Particularly, titanium alloys have been used for a limited time due to the difficulty of processing by high melting point despite low density, excellent mechanical properties and corrosion resistance compared to stainless steel or cobalt alloys. It is a material that is in the limelight.

상기한 티탄합금 중 치과용 보철분야에 널리 보급되어 사용되고 있는 것으로는 Ti-6Al-4V합금이 있다. Ti-6Al-4V합금은 티탄에 알루미늄(Al/aluminium)과 바나듐(V/vanadium)을 첨가하여 순수 티탄의 문제점을 개선한 것으로서, 순수 티탄에 비하여 기계적 강도가 약 60% 우수한 것을 알려져 있다.Among the titanium alloys, Ti-6Al-4V alloy is widely used and used in the dental prosthesis field. Ti-6Al-4V alloy is an improvement of the problem of pure titanium by adding aluminum (Al / aluminium) and vanadium (V / vanadium) to titanium, it is known that the mechanical strength is about 60% superior to that of pure titanium.

그러나 이처럼 Ti-6Al-4V합금으로 제조된 치과용 보철은 바나듐의 경우 세포 독성이 있고, 알루미늄의 경우 알츠하이머병(Alzheimer's disease)과의 밀접한 인과관계 및 잠재적 신경독성이 논의되고 있는 등 각종 유해성 논란으로 보철로 사용하는 데 한계가 따르는 문제점이 있었다.However, dental prostheses made of Ti-6Al-4V alloy are cytotoxic in case of vanadium and close causality and potential neurotoxicity with Alzheimer's disease in case of aluminum. There was a problem with the limitation of using as a prosthesis.

따라서 인체에 무해한 재료를 첨가하여 생체독성이 전혀 없고 기계적 성질과 가공성 등이 향상된 티탄합금을 개발하기 위한 노력이 활발히 이루어지고 있고, 최근에는 생체 적합성이 우수한 티탄합금이 개발되기에 이르렀다.Therefore, efforts have been made to develop titanium alloys having no biotoxicity and improved mechanical properties and processability by adding materials that are harmless to humans, and recently, titanium alloys having excellent biocompatibility have been developed.

하지만 인체에 전혀 무해하다 하여도 자신에게서 생성된 것이 아닌 외부물질이 구강 내에 자리를 잡게 되는 것이니 결국엔 보철에 의하여 보철 주위의 치아나 잇몸 등에 염증이 발병될 수밖에 없는 문제점이 있었다.However, even if it is harmless to the human body, the foreign material is not generated from itself is settled in the oral cavity, so there was a problem that the inflammation of the teeth or gums around the prosthetic by the prosthesis.

이와 같은 문제점을 해결하기 위하여 안출된 것이 치과용 항균 보철이다.In order to solve this problem is a dental antibacterial prosthesis.

도 1을 참조하면, 상기 치과용 항균 보철은 인공치근ㆍ인공치아와 같은 보철의 표면 전체 또는 잇몸과 대응하여 맞닿는 부분에 국한하여 나노실버 또는 플루오르(F/fluorine)(불소)로 이루어진 항균층이 코팅된 것을 특징으로 함을 알 수 있는 바, 상기 항균층은 구강 내 각종 균을 사멸하여 보철에 의한 인체 거부반응으로 염증이 발병되는 것을 억제한다.Referring to FIG. 1, the dental antimicrobial prosthesis has an antimicrobial layer made of nanosilver or fluorine (F / fluorine) limited to the entire surface of the prosthesis such as an artificial tooth and an artificial tooth or a portion corresponding to the gum. It can be seen that the coating is characterized in that the antimicrobial layer kills various bacteria in the oral cavity and suppresses the development of inflammation due to the rejection of the human body by the prosthesis.

그러나 이는 항균층이 단순히 코팅되어 있어 강도가 취약할 수밖에 없고, 타액에 의한 침식으로 단기간에 박리되어 지속적인 작용 및 효과를 기대할 수가 없기 때문에 반영구적으로 사용하기에 부적합한 문제점이 있었다.However, since the antimicrobial layer is simply coated, the strength is inevitably weak, and due to erosion by saliva, there is a problem in that it is unsuitable to use semi-permanently because it cannot be peeled off in a short period of time and expects continuous action and effect.

본 발명은 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 나노실버(nano silver)를 보철에 첨가하여 조성물을 구성함으로써 나노실버의 항균작용으로 보철에 의한 염증의 발병을 강력하게 억제할 수 있음은 물론 그 작용을 장기적으로 지속시킬 수 있는 나노실버가 함유된 치과용 보철을 제공하는 데 목적이 있다.
The present invention has been made in order to solve the problems of the prior art, by adding a nano silver (nano silver) to the prosthesis to configure the composition can be strongly suppressed the onset of inflammation due to the antibacterial action of nano silver. Of course, the object of the present invention is to provide a dental prosthesis containing nanosilver that can sustain its function in the long term.

상기한 기술적 과제를 달성하기 위한 본 발명은 티탄(Ti/titanium)을 주체로 하여 조성한 티탄합금으로 제조된 보철에 시술 후 상기 보철에 의한 구강 내 염증 발병을 억제하기 위한 항균성이 부가되도록 전체 중량%에 대하여 0.01~5중량%의 나노실버(nano silver)를 더 첨가하여 혼입되게 한 것을 특징으로 한다.The present invention for achieving the above technical problem is a total weight percent to add antibacterial to inhibit the development of oral inflammation caused by the prosthesis after the procedure to the prosthesis made of titanium alloy mainly composed of titanium (Ti / titanium) 0.01 to 5% by weight of nano silver (nano silver) is further added to be mixed.

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 나노실버가 함유된 치과용 보철을 나타내는 단면도이다.Figure 2 is a cross-sectional view showing a dental prosthesis containing nanosilver according to the present invention.

본 발명의 나노실버가 함유된 치과용 보철은 티탄(Ti/titanium)(5)을 주체로 하여 조성된 티탄합금으로 이루어지는 바, 티탄(5)에 전체 조성물을 기준으로 하여 기계적 성질을 개선하기 위한 18~25중량%의 지르코늄(6)(Zr/zirconium), 가공성을 향상시키기 위한 2~10중량%의 니오브(7)(Nb/niobium), 내식성을 높이기 위한 2~5중량%의 탄탈(8)(Ta/tantalum) 및 0.5~3중량%의 인듐(9)(In/indium)이 첨가된다.The dental prosthesis containing the nanosilver of the present invention consists of a titanium alloy mainly composed of titanium (Ti / titanium) (5), for improving mechanical properties based on the entire composition of titanium (5). 18-25 wt% zirconium (6) (Zr / zirconium), 2-10 wt% niobium (7) (Nb / niobium) for improving workability, 2-5wt% tantalum (8 for improving corrosion resistance (Ta / tantalum) and 0.5 to 3% by weight of indium (9) (In / indium) are added.

특히 본 발명은 보철(10)에 항균성을 부가함으로써 시술된 보철(10)에 따른 인체의 거부반응 등을 원인으로 하여 구강 내에 발병되는 각종 염증을 억제하기 위한 항균성물질이 더 첨가된다.In particular, the present invention further adds an antimicrobial substance for suppressing various inflammations occurring in the oral cavity due to the rejection of the human body according to the prosthesis 10 by adding antimicrobial activity to the prosthesis 10.

여기에서 항균성물질은 강력한 항균작용이 있는 나노실버(nano silver)(20)로서, 전체 중량%에 대하여 0.01~5중량%가 첨가된다. 이 때 나노실버(20)의 첨가량은 본 출원인이 거듭된 실험을 통하여 얻은 결과치로서, 만약 0.01중량% 이하를 첨가하면 효능이 미진하여 강력한 항균작용을 기대할 수가 없게 되고, 5중량% 이상을 첨가하면 75중량%를 첨가하였을 때와 동일한 작용이 발생하여 재료낭비를 초래하게 된다.Here, the antimicrobial material is a nano silver (nano silver) 20 having a strong antimicrobial action, and 0.01 to 5% by weight is added to the total weight. At this time, the addition amount of the nano silver 20 is the result obtained by the present inventors repeated experiments, if the addition of 0.01% by weight or less is not effective and can not expect a strong antimicrobial action, if added by 5% by weight or more 75 The same action as when added by weight causes waste of materials.

상기와 같이 구성되는 본 발명은 나노실버(20)가 혼합되어 보철(10)과 일체의 결정형을 이루기 때문에 보철(10)로부터 분리가 원천적으로 방지된다. 즉 나노실버(20)는 보철(10)의 제조과정에서 용해한 보철재료(티탄ㆍ지르코늄ㆍ니오브ㆍ탄탈 및 인듐)에 첨가되어 혼합되고, 이후 보철재료가 경화되면 완제품인 보철(10)에 내포되어 보철(10)과 한 덩어리가 되는 것이며, 이에 보철(10)로부터 분리가 방지되는 것이다.According to the present invention configured as described above, since the nano silver 20 is mixed to form an integral crystal form with the prosthesis 10, separation from the prosthesis 10 is prevented. That is, the nano silver 20 is added to and mixed with the prosthetic materials (titanium, zirconium, niobium, tantalum and indium) dissolved in the manufacturing process of the prosthesis 10, and then embedded in the finished prosthesis 10 when the prosthetic material is cured. The prosthesis 10 and the lump is to be prevented, thereby preventing separation from the prosthesis 10.

한편 나노실버(20)에 대하여 간략하게 살펴보면 다음과 같다.Meanwhile, the nano silver 20 will be briefly described as follows.

나노실버(20)는 은(Ag/Sliver) 입자를 1/10억 이하의 크기로 나노화한 것으로서, 연구보고에 의하면 약 650종의 세균과 바이러스를 멸균하고, 또 염소계열 보다 수십 배 강력한 살균력을 갖고 있으면서도 인체에는 전혀 무해하며, 균에 직접 작용하여 균의 세포막을 녹이는 한편 균의 전자전달계를 방해하여 균을 제거하므로 확실하고 탁월한 99.9%의 항균력을 자랑한다.Nanosilver 20 is nanoscaled silver (Ag / Sliver) particles to a size of less than 1 billion billion, according to the research reports sterilize about 650 kinds of bacteria and viruses, and tens of times more powerful sterilization than chlorine series It is harmless to the human body, but it directly acts on the bacteria, dissolving the cell membranes of the bacteria, and removing the bacteria by interfering with the electron transfer system.

주요 항균효과는 균의 세포 내 효소와 작용하여 영양물질의 대사기능, 즉 영양물질 유입 및 배출을 차단하고 호흡기능을 차단함으로써 세포 내 APT 생성을 막아 균의 생육정지 및 재생능력을 파괴, 사멸시킨다. 또 지속적으로 항균력을 방출시켜 균을 제어하므로 항균기능의 지속력이 뛰어나고, 세균들에 대한 내성이 발생 되지 않는다.The main antimicrobial effect is to interact with enzymes in the cells of the bacteria to block the metabolism of nutrients, ie, the influx and discharge of nutrients, and to block the respiratory function, thus preventing the production of APT in cells and destroying and killing the growth and regeneration of bacteria. . In addition, by releasing antimicrobial activity continuously to control bacteria, the antimicrobial function is excellent in persistence, and resistance to bacteria does not occur.

상기한 바와 같은 본 발명은 티탄합금으로 조성된 보철에 전체 중량%에 대하여 0.01~5중량%의 나노실버(nano silver)가 더 첨가된 것을 특징으로 하기 때문에 나노실버의 작용으로 구강 내 균의 서식이 강력히 억제되어 시술된 보철에 따른 인체의 거부반응 등에 기인한 각종 염증의 발병을 방지할 수 있고, 합금의 특성상 나노실버가 분리되는 현상이 없어 그 항균작용을 장기적으로 지속시킬 수 있는 이점이 있다.The present invention as described above is characterized in that the addition of 0.01 to 5% by weight of nano silver (nano silver) to the prosthesis made of titanium alloys with respect to the total weight by weight of the bacteria in the oral cavity by the action of nano silver. This strongly inhibited can prevent the onset of various inflammation due to the rejection of the human body according to the prosthesis, and there is no phenomenon that the nano silver is separated due to the characteristics of the alloy has the advantage of long-term antibacterial action. .
