ÖZET
 Çürük, travma, restorasyonlar, erozyon, atrizyon ve abrazyon gibi birçok faktöre bağlı olarak çok fazla madde kaybı olan ve endodontik tedavi sonrası daha da zayıflayan dişlerin nasıl restore edileceği her zaman bir sorun olmuştur. Endodontik tedavili dişlerin post ve kor sistemleri ile restorasyonu diş hekimliği pratiğindeki en riskli işlemlerden biridir. Endodontik tedavi geçirmiş bir dişin restoratif ve protetik tedavisi; kalan sağlıklı dokuların miktarına, uygulanan kor restorasyonunun prognozuna, kor yapısına destek olan post çeşidine ve post yüzeyine tutuculuğu artırmaya yönelik yapılacak işlemlere, restorasyonun genel olarak yapısal ve estetik kalitesi ile, klinik adaptasyonuna bağlıdır. Günümüzde estetik beklentilerin artması ve adezif sistemlerin gelişmesiyle birlikte post-kor sistemlerinin seçenekleri artmıştır. Giderek artan estetik ve biyolojik olarak uyumlu maddelere olan talep, metal olmayan post-kor sistemlerinin geliştirilmesine yol açmıştır. Fiberle güçlendirilmiş sistemler daha çok kullanılmaya başlanmıştır. Bu çalışmada, restorasyonların ağızda kalma oranı ve en yaygın başarısızlık tipleri açısından, döküm post kor ve fiber postlar ile ilgili retrospektif ve prospektif klinik çalışmalar gözden geçirilmiştir. İlave olarak yüzey işlemlerinin post sistemlerinin retansiyon başarısı üzerine etkileri ve yeni bir post-kor sistem olan yüksek performanslı polimer polyetherketoneketonesin üzerinde durulmuştur. Bu çalışmada, madde kaybı çok fazla olan endodontik tedavili dişlere uygulayacağımız tedaviye karar vermekte diş hekimlerine yardımcı olunması amaçlanmıştır.

ABSTRACT
 It has always been a problem to restore teeth that have lost too much tissue due to many factors such as caries, trauma, previous restorations, erosion, attrition and abrasion, and even weakened after endodontic treatment. The restoration of endodontically treated teeth with postcore systems is one of the most risky procedure in dental practice. Restorative and prosthetic treatment of a tooth that has undergone endodontic treatment generally depends on the amount of remaining healthy tissue, the prognosis of the applied core restoration, and the clinical adaptation of the restoration with structural and aesthetic qualities. Nowadays, with the increase of aesthetic expectations and the development of adhesive systems, the choice of post-core systems has increased. Demand for increasingly aesthetically and biologically compatible materials has led to the development of non-metallic post-core systems. Fiber-reinforced systems have started to be incorporated into routine clinical care more frequently. In this survey, retrospective and prospective clinical studies dealing with cast-post-and core and fiber posts were reviewed regarding the rate of survival of restorations and the most prevalent failures. In addition, the impacts of surface treatments on the retention success of post systems and a new post core sysytem named high performance polyetherketoneketones have been mentioned. The aim of this review; was to asist dentists in deciding the treatment to be applied to endodontically treated teeth with too much substance loss.
