Endokron Restorasyonlarda Marjinal ve İnternal Uyum: Derleme

Kron harabiyeti fazla olan kök -kanal tedavili molar dişlerin restorasyonunda, direkt ve indirekt restorasyonlar dahil olmak üzere farklı konvansiyonel tedavi seçenekleri bulunmaktadır. Endokronlar, intraradiküler post, kor ve kronu tek bir parçada birleştiren monoblok yapıda olan, geleneksel post -kor restorasyonlara alternatif olarak ortaya çıkmış güncel tedavi seçeneğidir. Marjinal ve internal uyum, protetik restorasyonların uzun dönem başarısını etkileyen en önemli faktörlerdendir. Restorasyonların marjinal uyumu yetersiz olduğu durumlarda, zamanla siman çözünmesine bağlı olarak diş ile restorasyon arasında oluşan boşluk bakteri ve yiyecek artıkları ile dolar. Bu da plak birikimi, çürük ve periodontal problemlere sebep olmaktadır. Bilgisayar destekli tasarım/ bilgisayar destekli üretim (CAD/CAM) sistemi ile daha iyi marjinal ve internal uyuma sahip restorasyonlar elde edilmektedir. CAD/CAM sistemlerinde görülen gelişmeler sonucu endokron restorasyonların kullanımını yaygınlaşmıştır ve başarılı protetik sonuçlar elde edilmektedir. Bu derlemenin amacı endokron restorasyonlar ve bu restorasyonların marjinal ve internal uyumları hakkında bilgi vermektir.

Marginal and Internal Adaptation of Endocrown Restorations: Review

There are different conventional treatment options, including direct and indirect restorations, for the restoration of root-canal-treated molar teeth with excessive crown destruction. Endocrowns are the current treatment option that has emerged as an alternative to traditional post-core restorations, which are monoblock structures that combine the intraradicular post, core and crown in a single piece. Marginal and internal fit are among the most important factors affecting the long-term success of prosthetic restorations. In cases where the marginal compatibility of the restorations is insufficient, the space formed between the tooth and the restoration due to cement dissolution over time is filled with bacteria and food residues. This causes plaque accumulation, caries and periodontal problems. Better marginal and internal fit restorations are obtained with the computer aided design/computer aided manufacturing (CAD/CAM) system. As a result of the developments in CAD/CAM systems, the use of endocrone restorations has become widespread and successful prosthetic results are obtained. The purpose of this review is to give information about endocrown restorations and their marginal and internal compatibility.
