 Son yıllarda yaygınlaşan bilgisayar destekli tasarım ve bilgisayar destekli üretim (CAD/CAM) sistemleri ve tek randevulu hasta başı tedaviler ile hem hekimlerin hem
de hastaların estetik beklentisi artmıştır. Daha estetik ve daha dayanıklı restorasyonlar üretmek için zirkonyanın optik ve mekanik özelliklerinin iyileştirilmesiyle birlikte
üretim aşamalarını kısaltacak, hızlandırılmış sinterleme protokolleri geliştirilmiştir. Kullanıma sunulan yeni sinterleme protokollerinin amacı zaman tasarrufu sağlamanın yanı sıra
zirkonyanın optik ve mekanik özelliklerini de geliştirmektir, ancak sinterleme hızı ve sıcaklığının değişmesi zirkonyanın fiziksel özellikleri üzerinde değişken etkiler oluşturduğundan
zirkonya restorasyonların klinik başarısını doğrudan etkiler. Bu derlemede, sinterleme parametrelerindeki değişikliklerin zirkonyanın mikro yapısı ile optik ve mekanik özellikleri
üzerindeki etkileri hakkında bilgi verilmiştir

The Effect of Altering Sintering Conditions on the Optical and Mechanical Properties of Zirconia

Öz

The aesthetic expectations of both physicians and patients have increased with computer aided design and computer aided manufacturing (CAD/CAM) systems and single appointment chair-side treatments that have become widespread in recent years. In order to produce more aesthetic and more durable restorations, accelerated sintering protocols have been developed that will shorten the production stages with the improvement of the optical and mechanical properties of zirconia. The aim of the new sintering protocols introduced is not only to save time but also to improve the optical and mechanical properties of zirconia; however, changes in sintering speed and temperature directly affect the clinical success of zirconia restorations as they have variable effects on the physical properties of zirconia. In this review, information is given about the effects of changes in sintering parameters on the microstructure and optical and mechanical properties of zirconia.
