Abstract

Monolithic zirconia has been widely used in fixed partial dentures due to high strength and fracture toughness. Nevertheless, the usage of monolithic zirconia in anterior restoration was limited because of opacity. Recently, esthetic monolithic zirconia blocks are developed by improving translucency and using various shading systems. Manufacturer introduces 3M $Lava^{TM}$ Esthetic with increased cubic phase and fluorescent ingredients is more esthetic than previous monolithic zirconia. This case report describes favorable anterior restorations using translucent monolithic zirconia.

단일 구조 지르코니아는 높은 강도와 파괴 인성을 갖고 있어 고정성 보철 치료에 많이 활용되고 있으나 지르코니아 자체의 불투과성으로 인한 심미적인 한계 때문에 전치부 사용에서 어려움이 있었다. 최근에는 기존 단일 구조 지르코니아보다 투과성이 우수하며, 다양한 착색법을 이용하여 심미성을 개선한 지르코니아 블록들이 개발되고 있다. 3M $Lava^{TM}$ Esthetic 지르코니아는 제조사에 따르면 육방정계 결정상의 비율을 증가시키고 형광성 성분을 추가하여 기존 지르코니아보다 심미성이 우수하다고 소개되고 있다. 본 증례들에서는 심미성을 개선한 단일 구조 지르코니아를 이용하여 전치부를 수복하였으며 기능적, 심미적으로 만족한 결과를 얻었기에 이를 보고하는 바이다.
