Description

자연골치환형 인공골과 그 제조방법Natural bone substituted artificial bone and its manufacturing method

본 발명은 자연골치환형 인공골과 그 제조방법에 관한 것이다.The present invention relates to a natural bone substituted artificial bone and a method of manufacturing the same.

특히 본 발명은 콜라겐과 탄산아파타이트로부터 제조된 자연골치환형 인공골및 그 제조방법에 관한 것이다. 더욱 상세하게는 동물의 조직이나 사람의 탯줄에서 추출된 I형 콜라겐과 탄산아파타이트로부터 제조된 자연골치환형 인공골 및 그 제조방법에 관한 것이다.In particular, the present invention relates to a natural bone substituted artificial bone produced from collagen and apatite carbonate and a method for producing the same. More specifically, the present invention relates to a natural bone substituted artificial bone produced from collagen type I and carbonate apatite extracted from an animal tissue or human umbilical cord and a method of manufacturing the same.

사람이나 동물의 치아나 뼈는 인산칼슘으로 이루어져 있으며, 생체와의 친화성에 있어서는 이 물질만큼 뛰어난 물질은 없다. 그러나 이 인산칼슘은 통상의 것으로서는 매우 취약하여 부스러지기 쉬운 단점이 있다. 사람이나 동물의 치아나 뼈에 있어서는 섬유소인 콜라겐이 인산칼슘 속에서 방직물이나 콘크리트 속에서의 철근과 같은 역할을 하여 인산칼슘이 파손되는 것을 막아주고 있는 것이다. 치아나 뼈는 사람이 성장하고 노화함에 따라서 뼈에서 콜라겐이 빠져나가서 뼈가 취약해지거나, 뼈에 손상을 받거나 충치 등으로 인하여 치아가 손상을 받아서 자연적으로 빠져버리거나 또는 인공적으로 빼어 버려야 하는 경우가 자주 발생하고 있다. 이 경우에는 인공적으로 치아나 뼈의 형상으로 성형하거나 또는 보강재를 사용하여 이식(inplant)하여야 한다.The teeth and bones of humans and animals are composed of calcium phosphate, and no substance is as good as this in terms of affinity with living organisms. However, this calcium phosphate is very weak as a conventional one has a disadvantage of brittle. In the teeth and bones of humans and animals, collagen, a fibrin, acts like a reinforcing bar in textiles or concrete in calcium phosphate to prevent calcium phosphate from being damaged. Teeth or bones often lose collagen from bones as a person grows and ages, making the bones vulnerable, damaged, decayed, decayed, damaged, decayed, or otherwise pulled out naturally or artificially. It is happening. In this case, it may be artificially molded into the shape of teeth or bones or implanted using reinforcement materials.

이러한 인공뼈나 인공치근은 다음과 같은 필요조건을 지니고 있어야 한다.These artificial bones or tooth roots must have the following requirements.

첫째 : 독성이 없어야 할 것.First: To be nontoxic.

둘째 : 적당한 물성을 가지고 있고, 체택에서 장시간 취약화하지 않아야 할것.Secondly, it should have proper physical properties and not be vulnerable for a long time in the house.

셋째 : 생체조직과 친화성이 좋아야 할 것.Third: Should have good affinity with living tissue.

이러한 조건을 만족시키는 물질에 관한 연구가 계속적으로 이루어지고 있다. 현재 까지는 이러한 인공치근이나 인공골 등으로서는 금속, 플라스틱 및 세라믹스 등 모든 분야에서 여러가지 종류의 소재가 사용되어 왔다. 그 예를 다음에 열거한다.There is a continuous research on substances that satisfy these conditions. Until now, various kinds of materials have been used in all fields such as metal, plastic, and ceramics as the artificial tooth or artificial bone. Examples are listed below.

1) 금속 티타니움 : 이 금속은 자원적으로 풍부하고 가볍고 내식성이 우수하여 생체 친화성이 비교적 좋다.1) Metal Titanium: This metal is abundant in resources, light in weight and excellent in corrosion resistance, so it has a relatively good biocompatibility.

2) 생체활성 유리 : 바이오글라스(Bioglass)라고도 불리워지며 골에 이식되는 유리의 표면에 인산칼슘의 박막을 석출시켜서 사용된다.2) Bioactive glass: Also called Bioglass, it is used by depositing a thin film of calcium phosphate on the surface of glass implanted into bone.

3) 카본 : 인공치근은 유리형 카본 등이 알려지고 있다.3) Carbon: Artificial roots are known as free carbon.

4) 알루미나 : 세라믹스는 일반적으로 미세한 입자가 소결된 다결정이며 이들은 모두 압축응력은 강하나 인장강도가 약한 취약한 재료이다. 알루미나는 이러한 결점을 개량하여 등장한 단결정 알루미나가 사용되고 있다.4) Alumina: Ceramics are generally polycrystalline sintered with fine particles, all of which are weak materials with strong compressive stress but weak tensile strength. As the alumina, a single crystal alumina is used, which has been developed by improving these drawbacks.

5) 지르코니아 : 지르코니아는 결정학적으로 3종이 있으며, 상전이시에 체적의 변화를 수반하기 때문에 자체 붕괴하여 그대로는 사용할 수 없다. 따라서 지르코니아에 산화잇트륨, 산화칼슘, 산화마그네슘 등을 가하여 안정화시켜서 사용된다.5) Zirconia: There are three kinds of zirconia crystallographically. It cannot be used as it is due to its own decay because it involves volume change during phase transition. Therefore, it is used to stabilize it by adding yttrium oxide, calcium oxide, magnesium oxide, etc. to zirconia.

6 ) 하이드로시 아파타이트(HAP) : 하이드록시아파타이트의 세라믹스를 이식하면 이 소결체는 흡수되지 않고 동시에 섬유성 피막에 의한 피포도 일어나지 않는다.6) Hydrocypatite (HAP): When the ceramics of hydroxyapatite are implanted, the sintered body is not absorbed and at the same time, the coating by the fibrous coating does not occur.

7 ) 인산칼슘(TCP) : 인산칼슘은 하이드록시아파타이트와 마찬가지로 인산칼슘이지만 결정구조는 전혀 다르며, 용해성도 어느정도 크고 생체내에서 점차로 흡수된다.7) Calcium Phosphate (TCP): Like hydroxyapatite, calcium phosphate is calcium phosphate, but its crystal structure is completely different, its solubility is somewhat large, and it is gradually absorbed in vivo.

최근에는 다른 성분을 첨가하여 소결성이나 물성을 개선하는 연구가 진행되고 있다. 그러나 이러한 세라믹스 재료들은 모두 높은 온도에서 소결하여 사용되기 때문에 부스러지기 쉬운 결점이 있다. 그 때문에 이러한 소결체 재료들은 아직까지는 임상에의 사용이 제한되어 있다.In recent years, research is being conducted to improve the sinterability and physical properties by adding other components. However, all of these ceramic materials are sintered at high temperatures and thus have a disadvantage of brittleness. For this reason, these sintered materials are still limited in clinical use.

본 발명자는 이러한 세라믹스 소재의 자연골치환형 인공골에 관하여 오랜 연구를 행하여 왔다.The present inventors have been doing a long research about such natural bone substituted artificial bone of ceramics.

본 발명자는 탄산아파타이트 소재 또는 탄산아파타이트에 약 13%(v/v)까지의 정제된 이산화규소(Sio2)를 첨가하고 여기에, 콜라겐을 작용시켜서 인공골을 제조하여 생체내에 이식하면 부스러지기 쉬운 탄산아파타이트가 부스러지지 않으며 골내에 매입후 탄산아파타이트가 재생골형성에 필요한 무기성분의 공급원으로서 작용하여 점차로 흡수되어 자연골로 완전히 치환되는 놀라운 사실을 발견하여 본 발명을 완성하였다.The present inventors add up to about 13% (v / v) of purified silicon dioxide (Sio 2 ) to the apatite carbonate material or the apatite, and the collagen is acted on to produce artificial bone, which is easily broken when implanted in vivo. Apatite carbonate does not crumble, and after embedding in bone, it was found that the amazing fact that apatite carbonate acts as a source of inorganic components necessary for regeneration bone formation is gradually absorbed and completely substituted with natural bone.

따라서 본 발명의 목적은 탄산아파타이트 또는 탄산아파타이트에 이산화규소를 첨가하고 여기에, 콜라겐을 작용시키고 이를 적당한 형태로 성형시켜서 제조된 자연골치환형 인공골을 제공하는 것이다.Accordingly, an object of the present invention is to provide a natural bone substituted artificial bone prepared by adding silicon dioxide to apatite carbonate or apatite carbonate, and then acting collagen and molding it into a suitable form.

따라서, 본 발명의 또다른 목적은 탄산아파타이트 또는 탄산아파타이트에 이산화규소를 첨가하고 여기에, 사람의 탯줄에서 추출된 인체 I형 콜라겐을 작용시키고 적당한 형태로 성형시켜서 제조된 자연골치환형 인공골을 제공하는 것이다.Therefore, another object of the present invention is to provide a natural bone substitute artificial bone prepared by adding silicon dioxide to apatite carbonate or apatite and acting on the human body type I collagen extracted from the human umbilical cord and molding it into a suitable form It is.

본 발명의 또다른 목적은 탄산아파타이트 또는 탄산아파타이트에 이산화규소를 첨가하고 여기에, 인체의 탯줄에서 추출된 인체 I형 콜라겐을 작용시키고 적당한 형태로 성형시켜서 자연치환형 인공골을 제조하는 제조방법을 제공하는 것이다.Another object of the present invention is to add a silicon carbonate to apatite carbonate or apatite carbonate, and to act on the human body type I collagen extracted from the umbilical cord of the human body to form a suitable form to produce a natural substituted artificial bone It is.

본 발명에서는 동물의 조직에서 추출 및 정체하여 제조된 콜라겐 및 사람의 탯줄에서 추출 및 정제한 인체 I형 콜라겐을 사용하며 탄산아파타이트 또는 탄산아파타이트에 이산화규소를 첨가한 무기질의 량은 용량으로 70∼95%를 사용하며, 콜라겐의 사용량은 5∼30%이다.In the present invention, using the collagen produced by the extraction and stagnation in animal tissues and the human body type I collagen extracted and purified from the human umbilical cord, the amount of inorganic matter added to the silicon carbonate or apatite is 70-95 % Is used, and the amount of collagen is 5 to 30%.

본 발명의 방법으로 탄산아파타이트 또는 탄산아파타이트에 이산화규소를 첨가하고 여기에 콜라겐을 작용시켜서 제조된 자연골치환형 인공골은 통상으로 사용되는 인공골로 현재에 사용되고 있는 세라믹 소재의 인공골과 그 물성을 비교하면 다음 표 1과 같다.The natural bone substituted artificial bone produced by adding silicon dioxide to apatite carbonate or apatite and collagen by the method of the present invention is a commonly used artificial bone. It is shown in Table 1 below.

[표 1]TABLE 1

본 발명의 인공골과 기존의 인공골의 물성 비교Comparison of physical properties of artificial bone of the present invention and conventional artificial bone

* HCP : 하이드록시 아파타이트* HCP: hydroxy apatite

** TCP : 트리칼슘 포스페이트** TCP: Tricalcium Phosphate

즉 천연골을 제외한 인공골결손부보충재로서 지금까지는 무기질로만으로 구성된 하이드록시아파타이트나 트리칼슘포스페이트 및 산호출 매입하거나 유기질인 콜라겐 성분만을 매입하여 골결손부위를 충전하여 왔다. 그러나 본 발명의 방법에 의하여 탄산아파타이트 및 탄산아파타이트에 이산화규소를 첨가시키고 여기에 콜라겐을 작용시켜서 제조된 자연골치환영 인공골은 다음과 같은 특징이 있다.That is, as an artificial bone defect supplement except natural bone, until now, hydroxyapatite or tricalcium phosphate and coral extracts composed only of minerals have been purchased or organic collagen components have been purchased to fill bone defects. However, the natural bone replacement artificial bone produced by adding silicon dioxide to apatite and apatite carbonate by the method of the present invention and collagen to it has the following characteristics.

1. 천연골조직내의 최다 무기질 성분인 탄산아파타이트와 최다 유기질 성분인 콜라겐을 복합화하여 생체골의 조성에 가깝게 모방하여 인공골을 제조하였다.1. Artificial bones were prepared by complexing the composition of apatite carbonate and collagen, which is the most inorganic component in natural bone tissue, to the composition of living bone.

2. 골내에 매입후 탄산아파타이트가 재생골형성에 필요한 무기성분의 공급원으로서 작용하며 점차 흡수되어 자연골로 완전히 치환된다.2. After embedding in bone, apatite carbonate acts as a source of inorganic components necessary for regeneration bone formation and is gradually absorbed and completely replaced with natural bone.

3. 골재생초기 섬유조직형성기간에 필요한 콜라겐섬유화기간이 미리 제공된 콜라겐에 의하여 단축되므로 골재생기간을 크게 단축시킨다.3. Collagen fibrosis period required for the initial bone regeneration period is shortened by the collagen provided in advance, greatly reducing the bone regeneration period.

4. 천연단백질인 콜라겐을 고형제로 사용함으로써 사용시 골결손부위의 형태에 알맞게 성형이 가능하다.4. By using collagen which is a natural protein as a solid agent, it can be molded to fit the shape of bone defect in use.

5. 면역성을 제거한 콜라겐을 이용하므로 천연골중 자가골을 제외한 동결건조 동종골및 이종골에 비하여 우수한 생체친화성을 가진다.5. Since collagen has been removed from immunity, it has superior biocompatibility compared to freeze-dried allogeneic bone and xenograft except natural bone in natural bone.

6. 사람의 탯줄을 사용하는 경우에는 추출한 인체 I형 콜라겐은 생체친화성이 더욱 좋다.6. If human umbilical cord is used, human body type I collagen is more biocompatible.

7. 콜라겐과 탄산아파타이트간의 결합에 수산화나트륨을 사용하여 그 결합을 더욱 좋게 하였다.7. Sodium hydroxide was used to bind collagen and apatite to make the bond more favorable.
