치과용 포세린을 금속에 용착시키는 금속-세라믹(metal-ceramic) 수복물은 흔히 PFM(porcelain-fused-to-metal)이라 불리며 심미성과 내구성 모두를 갖추어 1970년대부터 오늘날까지 성공적으로 사용되어 왔다. 그러나 한편으로 PFM 수복물에서 금속 코핑으로 인한 광학적 불투과성, 금속성분의 용출로 치은의 변색이 나타나는 등 불완전한 심미성을 피할 수 없다. 또한 니켈, 베릴리움 함유의 비귀금속 합금은 국소적, 전신적 위해작용을 일으킬 수 있다. 부식저항성이 뛰어난 고귀금속 합금을 내부 금속 코핑으로 사용하면 이러한 부작용은 줄일 수 있으나 이 역시 금속 코핑으로 인한 불완전한 심미성은 해결할 수 없다. 더욱이 최근 금값의 폭등으로 금속-세라믹(metal-ceramic) 수복 시스템을 대체할 만한 올세라믹(all-ceramic) 수복 시스템의 필요성이 커졌다.
Currently there is no dental ceramic material can be used in all dental situations need to be restored. However, in view of recent clinical reports, the most viable alternative is zirconia ceramic. Clinical success of dental zirconia restorations strongly depends on proper selection of materials, accurate laboratory procedure and final cementation, which can be achievable with the correct understanding of zirconia. As dental materials, zirconia ceramics have a very bright future, because they are being used increasingly in the anterior region as implant fixtures, as well as crown and bridge restorations and implant abutments. Although many dental ceramics are gone from the market, new materials can replace zirconia will not be available in the foreseeable future.
