Diş hekimliğinde estetik beklentinin artması, metal içermeyen diş rengindeki restorasyonlarla ilgili araştırmaların artmasına
sebep olmuştur. Seramik materyallerinde son 10 yılda yaşanan gelişmeler tam seramik uygulamalarının yaygınlaşmasına yol
açmıştır. Tam seramiklerin en önemli dezavantajı kırılmaya karşı yatkınlıklarıdır. Literatürler seramik materyalindeki
kırılmanın, restorasyonun başarısızlığına neden olan rapor edilmiş komplikasyonlar arasında en sık rastlanılan komplikasyon
olduğunu göstermektedir. Bir tam seramik restorasyonun dayanıklılığı, dayanak materyalin özelliklerine olduğu kadar,
kullanılan seramik materyaline, alt yapı-üst yapı bağlantısına, kuronun kalınlığına, restorasyonun dizaynına ve yapıştırma
tekniğine de bağlıdır. Tam seramik restorasyonların başarıyla uygulanabilmesi klinisyenin endikasyona uygun materyal
seçimi ayrıca doğru üretim ve yapıştırma tekniği kullanmasıyla mümkün olabilmektedir. Bu çalışmanın amacı; tam seramik
sistemlerle ilgili son yıllarda yapılmış araştırmalara dayanarak restorasyonların dayanıklılığını arttırmaya yönelik önerilerde
bulunmak ve klinisyenlere doğru simantasyon tekniğini belirlemede rehber oluşturmaktır. Tam seramik sistemlerle tedavi
başarısını arttırmak için daha fazla sayıda klinik araştırma sonuçlarına ihtiyaç duyulmaktadır.
