Abstract

The present invention provides a zirconia block composition in which 16 types of zirconia blocks having a unique tooth color are formed by mixing zirconia powder (zpex-4) with yellow, pink, and gray powder in a predetermined ratio. According to an embodiment of the present invention, since 16 kinds of zirconia blocks having natural tooth color are molded by using 16 kinds of zirconia block compositions acquired by mixing zirconia powder with yellow, pink, and gray powder in a certain ratio, a user can choose the color of a crown according to the color of the user's teeth, thereby increasing the user's satisfaction. In addition, since a zirconia block with color tone from the beginning is molded by mixing zirconia powder with yellow, pink, and gray powder in a certain ratio, difficulties caused by coloring or coating work are removed and manufacturing time of zirconia crowns is significantly reduced, thereby increasing productivity.

Description

지르코니아 크라운 조성물{Zirconia Crown Composition}Zirconia Crown Composition

본 발명은 지르코니아 블록 조성물에 관한 것으로, 좀 더 상세하게는 투광성 및 색조 대응이 용이하고, 우수한 강도 및 자연 치아와 같은 계조를 가지는 16종 지르코니아 블록 성형을 위한 지르코니아 블록 조성물에 관한 것이다. The present invention relates to a zirconia block composition, and more particularly, to a zirconia block composition for molding 16 kinds of zirconia blocks, which is easy to transmit light and corresponds to a color tone, and has excellent strength and gradation like natural teeth.

일반적으로 지르코니아는 Baddelyite(ZrO2)광물에서 얻을 수 있는 재료로써 우수한 특성으로 인하여 여러 분야에서 사용되고 있다. 예전의 지르코니아는 소결 후 냉각과정에서 많은 균열이 발생하고 그에 따른 강도 저하로 그 자체로는 사용이 거의 불가능하였다. 하지만 여기에 CaO나 Y2O3와 같은 안정화제를 첨가하면 이러한 상변태가 억제되어 고온 상인 정방정상이 상태가 유지된다. In general, zirconia is a material that can be obtained from baddelyite (ZrO2) minerals and is used in various fields due to its excellent properties. The old zirconia had many cracks in the cooling process after sintering, and it was almost impossible to use by itself due to a decrease in strength. However, if a stabilizer such as CaO or Y2O3 is added here, this phase transformation is suppressed and the tetragonal state, which is a high temperature phase, is maintained.

안정화제를 첨가하여 녹인 후 이를 천천히 냉각시키면 단결정의 큐빅 지르코니아가 생성된다. 이것이 일반적으로 큐빅이라고 불리는 인조 다이아몬드로써 색과 모양은 다이아몬드와 비슷하지만 가격은 수천 분의 일에 불과한 것으로 대부분의 사람들이 쉽게 접할 수 있는 제품화 되어 있다. A single crystal cubic zirconia is produced when a stabilizer is added and melted and then cooled slowly. This is an artificial diamond generally called cubic, which is similar in color and shape to diamonds, but costs only a few thousandths, and has been commercialized so that most people can easily access it.

이렇게 안정화제를 첨가한 것을 첨가제 양에 따라 ‘안정화-지르코니아(Fully Stabilized ZrO2)’라고 부르는데 반하여, 안정화제를 ‘조금만’ 첨가하여 부분적으로만 안정화시킨 것을 ‘부분안정화-지르코니아(Partially Stabilized ZrO2; PSZ)’라고 부른다. 이것이 우리가 일반적으로 일컫는 강도가 높은 지르코니아이다. The stabilizer added in this way is called 'Fully Stabilized ZrO2' depending on the amount of the additive, whereas the 'Partially Stabilized ZrO2 (PSZ) )' is called. This is what we commonly call high-strength zirconia.

부분안정화 지르코니아는 준 안정상인 정방정상이 상온에서도 유지되어 균열이 없을뿐더러, 외부에서 하중이 가해질 때 정방정에서 단사정으로 상전이를 하여 부피를 팽창시킴으로써 외부의 충격을 효과적으로 흡수한다. 따라서 이 부분안정화 지르코니아의 강도는 철강에 버금 갈 정도로 매우 높을 뿐만 아니라, 경도가 높고 고온에도 견딜 수 있어 현재 산업계에서 널리 응용되고 있다. Partially stabilized zirconia maintains its metastable tetragonal phase even at room temperature without cracking, and when an external load is applied, it changes its volume from tetragonal to monoclinic to expand its volume, effectively absorbing external shocks. Therefore, the strength of this partially stabilized zirconia is very high, comparable to that of steel, and it has high hardness and can withstand high temperatures, so it is widely applied in industry.

최근 생활수준의 향상으로 치아수복물에 대하여도 심미적 측면에 대한 사용자의 기대치가 높아지고 있으며, 크라운과 같이 치아 전체를 감싸는 치아수복물의 경우 기존의 금속제 치아수복물보다 뛰어난 강도를 보이며 심미성까지 우수한 지르코니아를 이용한 치아수복물의 수요가 더욱 높아지는 추세이다.Recently, with the improvement of living standards, users' expectations for esthetic aspects of dental restorations are also increasing. In the case of dental restorations that cover the entire teeth, such as crowns, they show superior strength than existing metal restorations and are made of zirconia with excellent esthetics. There is a growing demand for restorations.

지르코니아를 치아수복물로 사용하기 위해서 자연치아와 유사한 심미성을 향상시키기 위해 지르코니아 단독 재료로 치아수복물을 제조하기보다는 하부의 지르코니아 세라믹('지르코니아 코어'라고도 함) 위에 도재(porcelain)층을 코팅 형태로 축성하는 방식으로 제조한 치아수복물이 더욱 선호되기도 한다. 이때 도재층으로 레진 및 세라믹 등이 있다.In order to use zirconia as a dental restoration, in order to improve esthetics similar to natural teeth, a porcelain layer is layered in the form of a coating on the lower zirconia ceramic (also called 'zirconia core') rather than making a dental restoration with zirconia alone. Dental restorations manufactured in this way are preferred. In this case, the porcelain layer includes resin, ceramic, and the like.

이처럼 지르코니아 표면에 레진 또는 세라믹을 코팅하여 보철물에 부착하게 되는데, 이때 지르코니아에 접착시킨 레진 또는 세라믹이 박리한다든지, 보철물에 접합시킨 지르코니아가 분리하여 떨어져 나가는 현상이 시술 건수의 약 30%에 이르는 것으로 알려져 있다. 즉, 지르코니아 소재는 표면이 매끄럽고 캡핑(capping) 시에 접착강도가 약하여 시술 후 박리되는 현상이 번번히 발생하고 있는 실정이다.In this way, resin or ceramic is coated on the zirconia surface and attached to the prosthesis. At this time, the phenomenon that the resin or ceramic adhered to the zirconia peels off or the zirconia bonded to the prosthesis separates and falls off accounts for about 30% of the number of procedures. is known That is, the zirconia material has a smooth surface and has a weak adhesive strength during capping, so peeling occurs frequently after treatment.

따라서, 많은 비용을 들여 부착한 고가의 치아수복물이 탈착하는 경우에는 재 시술에 따른 환자의 육체적, 경제적 손실을 초래하게 되며, 처음 시술하는 것과 동일한 과정을 반복해야 하므로 환자는 시간적 손실과 더불어 많은 불편을 겪게 되는 문제점이 있었다.Therefore, when expensive dental restorations attached at high cost are detached, it causes physical and economic loss to the patient due to re-treatment. There was a problem with the

또한, 지르코니아 표면에 레진 또는 세라믹을 코팅하거나 착색하는 작업의 어려움과 작업시간의 증가로 생산성이 떨어지는 문제점이 있었다. In addition, there is a problem in that the productivity is lowered due to the difficulty of coating or coloring the resin or ceramic on the zirconia surface and the increase in working time.
