초록

지르코니아 강화 리튬 실리케이트 세라믹 재료는, 현재 널리 사용되고 있는 e.max(리튬디실리케이트 세라믹) 재료에 비하여 더 개선된 강도를 지니고 있다. 단일 크라운의 수복에 사용될 수 있으며, 1.5mm 의 두께를 확보하는 것이 예지성 있는 치료를 위해 매우 중요하다. Celtra Duo의 경우 열처리를 수행하는 것이 강도나 마모 저항성 측면에서 도움이 될 것이다. 접착을 위해서는 불산의 처리가 도움이 되며, 너무 짧은 시간의 불산은 접착 강도의 개선에 도움을 주지 못할 수 있으므로 충분한 시간의 불산 처리가 필요하다. 지르코니아 강화 리튬 실리케이트 세라믹 재료는 실험실 연구가 지속적으로 수행되고 출판되고 있지만, 아직 신뢰할만한 임상연구는 매우 부족한 실정이다. 추가적인 임상연구를 통해 과학적인 근거를 마련하는 것이 매우 중요한 부분이 될 것이다.

The zirconia-reinforced lithium silicate ceramic material is a material in which lithium silicate glass contains about 10% by weight of zirconia oxide (zirconia oxide). This material has both the advantages of glass ceramics and zirconia, and it is attracting attention as a CADCAM material for single tooth restoration. ZLS materials have improved strength compared to widely used e.max (lithium disilicate ceramic) materials. It can be used for single crown restoration and ensuring a thickness of 1.5 mm is very important for reliable treatment. In the case of Celtra Duo, heat treatment may be helpful in terms of strength and abrasion resistance. Hydrofluoric acid treatment is helpful for bonding and hydrofluoric acid for a short time may not help to improve the bonding strength. Although zirconia-reinforced lithium silicate ceramic materials have been continuously conducted and published in the laboratory, reliable clinical studies are still lacking. Additional clinical studies will be a very important part of establishing a scientific basis.
