Abstract

Objectives: This study evaluated stress distrubitions formed by oblique forces indental hard tissues, base materials and restorations of endodontically treatedpermanent mandibular first molars that were restored with different basematerials and direct composite restorations by using 3D-FEA method.Materials and Methods: For two different restorative approaches; an MO cavitydesign and a MOD cavity design was created. Then root canal obturation wasmodeled. Composite resin (CR), conventional glass ionomer cement (GIC), fiberreinforced composite resin (FRC), resin modified glass ionomer cement(RMGIC), flowable composite (FC), and bulk-fill composite resin (BF) were usedas base materials. Von Mises, compressive and tensile stresses in enamel, dentin,base materials and final restoration were analyzed using finite element stressanalysis method.Results: Regarding the resulting stresses, CR caused highest stresses and RMGICcaused lowest stresses in enamel, base material, and final restoration. RMGICcaused highest stresses and CR caused lowest stresses in dentin. It was noted thatMOD cavity design caused more stress than MO cavity design for all analyzedmaterials.Conclusions: Materials with elastic moduli similar to dentin; FRC and GIC, maybe better choice to avoid high stresses within the tooth and restoration.

Özet

Amaç: Bu çalışmada diş sert dokularında, kaide materyalinde ve restorasyonda oblik kuvvetlerin oluşturduğu stres dağılımları, farklı kaide materyalleri ve direkt kompozit restorasyonla restore edilen endodontik tedavili daimî mandibular ilk molar dişlerde 3B-SEA metodu ile değerlendirildi. Gereç ve Yöntemler: İki farklı restoratif yaklaşım için; MO kavite tasarımı ve MOD kavite tasarımı oluşturuldu. Sonra kök kanal tedavisi modellenmiştir. Kompozit rezin (CR), geleneksel cam iyonomer siman (GIC), fiberle güçlendirilmiş kompozit rezin (FRC), rezin modifiye cam iyonomer siman (RMGIC), akışkan kompozit (FC) ve Bulk-Fill kompozit rezin (BF) kaide olarak kullanılmıştır. Von Mises, basınç ve çekme stresleri; mine, dentin, kaide materyalleri ve nihai restorasyonda sonlu elemanlar stres analizi yöntemi kullanılarak analiz edildi. Bulgular: Ortaya çıkan stresler ile ilgili olarak; mine, kaide materyali ve nihai restorasyonda CR en yüksek streslere ve RMGIC en düşük streslere neden olmuştur. Dentinde, RMGIC en yüksek strese ve CR en düşük strese neden oldu. MOD kavite tasarımının, analiz edilen tüm materyaller için MO kavite tasarımından daha fazla strese neden olduğu not edildi. Sonuçlar: Dentine yakın elastik modülüsü olan materyaller; FRCR ve GIC, diş ve restorasyonda yüksek streslerden kaçınmak için daha iyi bir seçenek olabilir.
