Zirkonya İle Güçlendirilmiş Lityumsilikat Cam Seramikler

Özellikle son 20 yıldır artan teknolojik ilerleme ve yükselen estetik beklentiye bağlı olarak tam seramik sistemlerin sabit protetik restorasyon yapımında kullanımı artmıştır. Kırılgan yapıya sahip seramik materyallerinin estetik beklentileri karşılarken aynı zamanda yüksek dayanıklılığa sahip olması gerekmektedir. Bu nedenle estetik özelliği yüksek ancak kırılgan olan cam seramiklere güçlendirici ajanlar eklenerek dayanıklılığın artırılması hedeflenmiştir. Zirkonya ile güçlendirilmiş lityum silikat cam seramikler, yakın zamanda geliştirilmiş seramik malzemelerdir. Üretim tekniklerine göre optik ve mekanik özellikleri değişkenlik gösteren ZLS seramikler CAD/CAM ile veya ısı ile presleme tekniği ile üretilmektedir. Bu derlemede zirkonya ile güçlendirilmiş lityum silikat cam seramik materyallerinin üretimi, klinik kullanımı, fiziksel ve optik özelliklerinden bahsedilecektir.

Anahtar Kelimeler:
