ENDOKRON RESTORASYONLARINDA GÜNCEL GELİŞMELER: GELENEKSEL DERLEME

Abstract

Endodontik tedavi görmüş dişlerde restoratif yaklaşım, kalan diş dokusunun miktarı, fonksiyonel gereksinimler ve estetik beklentilere bağlı olarak değişmektedir. Geleneksel post kor sistemleri ve kron restorasyonları uzun yıllar boyunca standart tedavi yöntemi olarak kullanılsa da diş yapısında ek madde kaybına yol açabilmekte ve başarısızlık riskini artırabilmektedir. Bu nedenle, son yıllarda minimal invaziv yaklaşım ilkeleri doğrultusunda geliştirilen endokron restorasyonları dikkat çekmektedir. Endokronlar, özellikle posterior bölgede yaygın harabiyeti olan kanal tedavili dişlerde tercih edilmekte ve pulpa odası retansiyonundan yararlanarak ilave post gereksinimini ortadan kaldırmaktadır. CAD/CAM teknolojilerindeki ilerlemeler sayesinde lityum disilikat, zirkonya ve hibrit seramik gibi yüksek dayanıklılığa sahip materyallerle üretilebilen endokronlar başarılı sonuçlar sunmaktadır. Literatürde, endokronların kırılma direncinin post-kor ve geleneksel kronlara kıyasla daha yüksek olduğu bildirilmektedir. Bu derleme endokronların endikasyonları, kullanılan materyalleri, biyomekanik özellikleri, klinik performansı ve literatürdeki güncel bulguları incelemektedir. Endokronların başarısı; kavite şekli, bağlanma yüzeyi, siman ve uygulama tekniği gibi unsurlara bağlıdır. Gelişen adeziv sistemler sayesinde dentinle güçlü bağlantı sağlanarak restorasyon dayanıklılığı artmaktadır. CAD/CAM teknolojisiyle tek seansta uyumlu restorasyon üretimi hasta konforu ve klinik verimlilik açısından avantaj sağlar. Posterior bölgelerde oklüzal yükler nedeniyle uygun materyal ve kalınlık seçimi önem taşırken, artan estetik beklentiler seramik bazlı materyallere yönelimi artırmıştır. Mevcut kanıtlar, endokronların özellikle ciddi madde kaybına uğramış posterior endodontik tedavili dişlerin restorasyonunda güvenilir bir alternatif olduğunu göstermektedir. Ancak, uzun dönem prospektif klinik çalışmalara ihtiyaç devam etmektedir.

CURRENT DEVELOPMENTS IN ENDOCROWN RESTORATIONS: NARRATIVE REVIEW

Abstract

Restorative strategies for endodontically treated teeth are determined by the amount of remaining tooth tissue, functional demands, and esthetic needs. Although post–core and crown restorations have traditionally been the standard approach, they often require additional tooth removal and may compromise longevity. Consequently, minimally invasive alternatives such as endocrowns have emerged as a modern, tissue-preserving solution offering reliable and esthetic outcomes. Endocrowns are especially suited for posterior teeth that have undergone endodontic treatment and present with substantial structural loss, since they exploit the pulp chamber for retention and avoid the use of additional posts. With the evolution of CAD/CAM systems, these restorations can now be fabricated from advanced materials including lithium disilicate, zirconia, and hybrid ceramics, all of which provide high mechanical performance and predictable results. Research findings indicate that endocrowns frequently demonstrate superior fracture resistance compared with post–core assemblies and conventional crowns. This review aims to outline their indications, material choices, biomechanical advantages, clinical effectiveness, and the most recent insights from the literature. The success of endocrowns depends on cavity design, bonding surface, cement, and technique. Advances in adhesives enhance dentin bonding, while CAD/CAM fabrication improves comfort and efficiency. Proper material selection under occlusal stress ensures durability and esthetic satisfaction. Based on current evidence, endocrowns appear to be a dependable option for the rehabilitation of endodontically treated posterior teeth with extensive tissue loss. Nonetheless, further prospective long-term clinical investigations are required to validate their long-term reliability and success.
