Abstract (2. Language): 
The increasing demand for esthetics combined with health has stimulated dental research in metal-free tooth-colored restorations. Developments in ceramic materials have allowed more widespread application of all-ceramic restorations over the past 10 years. The most important disadvantage of all-ceramics is the susceptibility to fracture. The literature shows that fracture of the ceramic material is the most frequently reported complication resulting in failure. The strength of an all-ceramic restoration depends on the characteristics of the supporting material, ceramic material used, core-veneer bond strength, crown thickness, design of the restoration and also cementation techniques. Succesful application of all-ceramic restorations is possible with the clinician's appropriate material choice as well as accurate manufacturing and cementation techniques. The aim of this study was to make suggestions in order to improve the strength of restorations and to guide the clinicians to determine the accurate cementation technique based on recently published all-ceramic based literature. Additional clinical research results are required to improve the treatment success with all-ceramic systems.

Abstract (Original Language): 
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.
