ASTRACT Fixed denture consists a significant part of restorative den- tistry. In the structure of the metal supported ceramic restorations of metal substructure; lead to aesthetic drawbacks with reducing restoration’s semi-permeability, lead to local tissue reactions and corrosion toxicity may cause disadvantages that because of the nowadays high- resistance all ceramics have been developed. All-ceramic restorations made from zirconium for use in dentistry is spreading day by day because of the advantage of having high tensile strength, biocompatibility and being translucent. In this review, general information is given about zirconium material’s properties and places where used in restorative dentistry

Restoratif Diş Hekimliğinde Zirkonyum Uygulamaları

Öz

Sabit protezler restoratif diş hekimliğinin önemli bir bölümünü teşkil etmektedir. Metal destekli seramik restorasyonların yapısındaki metal alt yapının; restoras-yonun yarı geçirgenliğini azaltarak estetik sakıncalara yol açması, lokal doku reaksiyonuna ve korozyon toksisitesine sebep olabilmesi gibi dezavantajlarından ötürü günümüzde yüksek dirençli tam seramikler geliştirilmiştir. Yüksek gerilme direncine sahip olması, biyolojik uyumluluğu ve translüsent olması gibi avantajlarından ötürü zirkonyumdan üretilen tam seramik restorasyonların diş hekimliğinde kullanımı gün geçtikçe yaygınlaşmaktadır. Bu derlemede zirkonyum materyalinin özellikleri, restoratif diş hekimliğinde kullanıldığı yerler hakkında genel bilgi verilmektedir

Anahtar Kelimeler
