TAM SERAMİK RESTORASYONLARDA DAYANIKLILIĞI ETKİLEYEN FAKTÖRLER

Abstract

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.
