Description

광스캐닝성 향상제 조성물 및 물품의 광스캐닝성 향상 방법Optical scanning enhancer composition and method for improving optical scanning of articles

More specifically, a liquid optical scanning enhancer composition and an article, for example, a method for improving optical scanning of a tooth, gum or dental model, are disclosed.
임플란트와 같은 치아모형은 일반적으로 티타늄과 같은 금속으로 제조되어, CAD(computer aided design)/CAM(computer aided manufacturing)을 위한 광스캔시 빛이 난반사되지 않고 정반사되어 그 형상이 정확하게 인식되지 않는 문제점이 있다.Dental models, such as implants, are generally made of metals such as titanium, so that the light is not diffusely reflected but specularly reflected during light scan for computer aided design (CAD) / computer aided manufacturing (CAM). have.
종래에는 광스캐닝되는 금속 표면의 난반사를 유도하기 위하여 페이스트 형태의 도포재를 상기 금속 표면에 브러시 등의 도포 기구를 이용하여 도포하거나, 티타늄 분말을 고온 소결하여 상기 금속 표면에 융착시키는 방법(한국공개특허 제2010-0090564호)이 시도되었다. 그러나, 이러한 방법들은 난반사 표면을 형성하는 공정을 복잡하게 하여 치아모형의 제조비용을 증가시킬 뿐만 아니라 동일한 치아모형에서도 위치에 따라 불균일한 두께를 갖는 도막을 형성하거나, 복수개의 치아모형에서는 치아모형별로 서로 다른 두께를 갖는 도막을 형성함으로써 정확하고 재현성이 있는 광스캔 데이터를 얻지 못하게 하는 문제점이 있다.Conventionally, in order to induce diffuse reflection of a light-scanned metal surface, a paste-type coating material is applied to the metal surface using a coating device such as a brush, or titanium powder is sintered at high temperature to be fused to the metal surface. Patent 2010-0090564) has been attempted. However, these methods not only increase the manufacturing cost of the tooth model by complicating the process of forming the diffuse reflection surface, but also form a coating film having a non-uniform thickness depending on the position even in the same tooth model, or by the tooth model in the plurality of tooth models. There is a problem that it is impossible to obtain accurate and reproducible optical scan data by forming coating films having different thicknesses.

이하, 본 발명의 일 구현예에 따른 광스캐닝성 향상제 조성물을 상세히 설명한다. Hereinafter, a light scanning enhancer composition according to an embodiment of the present invention will be described in detail.
본 발명의 일 구현예에 따른 광스캐닝성 향상제 조성물은 백색 안료 100중량부, 바인더 수지 12~30중량부, 및 상기 바인더 수지를 용해시키는 용매 50~700중량부를 포함한다. The light scanning properties improver composition according to one embodiment of the present invention includes 100 parts by weight of a white pigment, 12-30 parts by weight of a binder resin, and 50 to 700 parts by weight of a solvent for dissolving the binder resin.
상기 바인더 수지의 함량이 상기 백색 안료 100중량부에 대하여 12중량부 미만이면, 상기 광스캐닝성 향상제 조성물로부터 형성된 도막이 수분(예를 들어, 타액)에 녹아 물품의 광스캐닝성이 저하될 뿐만 아니라 광스캐닝후에도 상기 도막이 물품으로부터 분리되기 어렵다. 한편, 상기 바인더 수지의 함량이 상기 백색 안료 100중량부에 대하여 30중량부를 초과하면, 상기 광스캐닝성 향상제 조성물로부터 형성된 도막은 위치별로 불균일한 두께를 갖게 되어 물품의 광스캐닝성이 떨어진다.When the content of the binder resin is less than 12 parts by weight with respect to 100 parts by weight of the white pigment, the coating film formed from the optical scanning enhancer composition is dissolved in water (for example, saliva), and the light scanning property of the article is lowered as well as light. Even after scanning, the coating film is difficult to separate from the article. On the other hand, when the content of the binder resin exceeds 30 parts by weight with respect to 100 parts by weight of the white pigment, the coating film formed from the light scanning properties improver composition has a non-uniform thickness for each position, the light scanning properties of the article is inferior.
상기 용매의 함량이 상기 백색 안료 100중량부에 대하여 50중량부 미만이면, 상기 백색 안료의 함량 비율이 과도해져서 상기 백색 안료의 균일한 도포가 어려워지고, 700중량부를 초과하면 도막 형성시 상기 백색 안료의 은폐력이 떨어진다.When the content of the solvent is less than 50 parts by weight based on 100 parts by weight of the white pigment, the content ratio of the white pigment becomes excessive, making it difficult to uniformly apply the white pigment. When the content of the solvent exceeds 700 parts by weight, the white pigment is formed during coating. Of hiding power.
상기 백색 안료는 물품의 광스캔시 난반사를 유도하고 상기 물품이 백색(즉, 치아 색상과 유사한 색상)을 띠게 하는 역할을 수행한다. The white pigment serves to induce diffuse reflection upon light scanning of the article and to make the article white (ie, a color similar to tooth color).
상기 백색 안료는 50~400nm(예를 들어, 100~300nm)의 평균입경을 갖는 것일 수 있다. 상기 백색 안료의 평균입경이 상기 범위(50~400nm)이내이면, 은폐력이 높아서 형태 인식에 유리할 뿐만 아니라 우수한 난반사 효과를 얻을 수 있다.The white pigment may have an average particle diameter of 50 ~ 400nm (for example, 100 ~ 300nm). If the average particle diameter of the white pigment is within the above range (50 ~ 400nm), the hiding power is high, not only advantageous to form recognition, but also excellent diffuse reflection effect can be obtained.

도 2a 내지 도 2e를 참조하면, 상기 실시예 1~4 및 비교예 1~2의 광스캐닝성 향상제 조성물을 사용하여 제조된 도막은 광스캐닝성이 우수한 것으로 나타났다. 그러나, 상기 비교예 1~2의 광스캐닝성 향상제 조성물을 사용하여 제조된 도막은 상기 평가예 4에서 살펴본 바와 같이 구강내에서는 타액에 잘 녹기 때문에, 구강내에서 사용될 경우 실제로는 광스캐닝성이 열악할 수밖에 없다. 반면에, 상기 비교예 3의 광스캐닝성 향상제 조성물을 사용하여 제조된 도막은, 상기 평가예 2 및 3에서 살펴본 바와 같이 두께가 불균일하여, 광스캐닝성도 열악한 것으로 나타났다.Referring to FIGS. 2A to 2E, the coating films prepared using the optical scanning enhancer compositions of Examples 1 to 4 and Comparative Examples 1 and 2 were found to have excellent optical scanning properties. However, since the coating film prepared by using the optical scanning enhancer composition of Comparative Examples 1 and 2 is soluble in saliva in the oral cavity as described in Evaluation Example 4, the light scanning property is actually poor when used in the oral cavity. Nothing else but to do. On the other hand, the coating film prepared using the optical scanning improver composition of Comparative Example 3, as described in the evaluation examples 2 and 3, the thickness was uneven, it was shown that the light scanning properties are also poor.
