A Contemporary Review on Traditional and Digital Post Systems

Abstract

This study examines post systems obtained through traditional and digital methods, analyzing the advantages and disadvantages of different materials. Metal post systems are divided into prefabricated and cast types, with prefabricated posts being more commonly preferred. Fiber post systems, with an elastic modulus similar to dentin, help reduce stress on the root surface. Ceramic post systems are aesthetic and biocompatible but may increase the risk of root fractures. Recently developed PEEK posts and CAD/CAM systems offer significant advantages in terms of precision and biomechanical compatibility. This review aims to shed light on current advancements in post systems and potential future applications in clinical practice.

Geleneksel ve Dijital Post Sistemleri Üzerine Güncel Bir Derleme

Abstract

Bu çalışma, geleneksel ve dijital yolla elde edilen post sistemlerini ele almakta ve farklı materyallerin avantaj ve dezavantajlarını incelemektedir. Metal post sistemleri, prefabrik ve döküm olmak üzere ikiye ayrılmakta olup prefabrik postlar daha yaygın olarak tercih edilmektedir. Fiber post sistemleri, dentine benzer elastik modüle sahip olmaları nedeniyle kök yüzeyindeki stresin azalmasını sağlamaktadır. Seramik post sistemleri estetik ve biyouyumlu olsalar da kök yüzeyinde kırık riskini artırabilmektedir. Son dönemde geliştirilen PEEK postlar ve CAD/CAM sistemleri, hassasiyet ve biyomekanik uyum açısından önemli avantajlar sunmaktadır. Bu derleme, post sistemlerinin klinik kullanımındaki güncel gelişmelere ve gelecekteki potansiyel uygulamalara ışık tutmayı amaçlamaktadır.
