Amaç: Bu çalışmanın amacı; ışıkla ve dual olarak polimerize olan iki rezin simanın farklı seramik sistemleri ile üretilmiş laminate veneerlerin mikroçekme bağlanma dayanımları üzerindeki etkilerini karşılaştırmalı olarak incelemektir.
Yöntemler: Altmış maksiller santral diş mine-sement birleşiminin 2 mm apikalinden akrilik rezin içine gömüldü ve laminate veneer preparasyonları tamamlandı. Restorasyonların mum modelajları 3B yazıcı yardımıyla üretildi. Dişler rastgele 3 gruba ayrıldı (n = 20) ve lityum disilikat, yüksek yoğunluklu mikronize lityum disilikat ve zirkonya ile güçlendirilmiş lityum silikat seramiklerden restorasyonlar üretildi. Seramik örnekler ayrıca rezin siman tipine göre ışıkla polimerize ve dual polimerize rezin siman olarak 2 alt gruba (n = 10) ayrıldılar ve simantasyonları yapıldı. Daha sonra dişler 1 yıllık klinik kullanıma eşdeğer hızlandırılmış yapay yaşlandırmaya maruz bırakıldı. Her dişin kronunun tam ortasından 1’er tane mikrobar elde edildi (n = 10) ve örneklere kopma gerçekleşene kadar 0,5 mm/dk yükleme hızında çekme kuvveti uygulandı. İstatistiksel analizler iki yönlü varyans analizi ve Tukey's Post-hoc testi kullanılarak yapıldı (P ≤ ,05).
Bulgular: Seramik ve rezin siman alt grubundaki örnekler karşılaştırıldığında aralarında istatistiksel olarak anlamlı fark bulunmuştur (P < ,001). Zirkonya ile güçlendirilmiş lityum silikat seramiklerin mikroçekme bağlanma dayanımları hem ışıkla polimerize olan hem de dual polimerize olan rezin siman gruplarında lityum disilikat seramiklere göre anlamlı seviyede düşük bulunmuştur (P < ,001). Dual polimerize olan rezin siman grubunun bağlanma dayanımı, ışıkla polimerize olan rezin siman grubundan istatistiksel olarak anlamlı seviyede düşük bulunmuştur (P < ,001).
Sonuç: Lityum disilikat laminate veneerler, zirkonya ile güçlendirilmiş lityum silikat veneerlerden daha yüksek bağlanma dayanımı göstermiştir. Yine ışıkla polimerize olan rezin siman, dual polimerize olan rezin simana göre daha etkili bağlanma dayanımı sağlamıştır.

Abstract
Objective: The aim of this study was to compare the effects of two resin cements polymerized in different ways on the microtensile bond strength of laminate veneers produced with different ceramic materials.
Methods: Sixty maxillary central incisor teeth were embedded in an acrylic resin 2 mm below the enamel-cement junction and laminate veneer preparations were completed. The wax models of the restorations were produced with a 3D printer. The teeth were randomly divided into 3 groups (n = 20) and restorations were produced with lithium disilicate, high-density micronized lithium disilicate and zirconia reinforced lithium silicate ceramics. Ceramic specimens were further divided into two groups (n = 10) according to the resin cement type as light-cure and dual-cure resin cement, and their cementation was performed. The teeth were then subjected to accelerated artificial aging equivalent to 1 year of clinical use. One microbar was obtained from the middle of the crown of each tooth
(n = 10) and tensile force was applied to the specimens at a loading speed of 0.5 mm/min until the fracture occurred. Statistical analyzes were performed using two-way analysis of variance and Tukey's Post-hoc test (P ≤ .05).
Results: Statistically significant difference was found between the ceramic type and resin cement subgroups (P < .001). The bond strength of laminate veneers produced with zirconia reinforced lithium silicate ceramic group was found significantly lower than that of lithium disilicate ceramic’s groups in both light-cured and dual-cured resin cement groups (P < .001). The dual-cure resin cement groups showed statistically significantly lower bond strength than the light-cure resin cement groups (P < .001).
Conclusion: The laminate veneers fabricated from lithium disilicate ceramics showed higher bond strength than that of zirconia reinforced lithium silicate veneers. Also, the light-cure resin cement provided more effective bond strength than dual-cure resin cement.
Keywords: Laminate veneer, lithium disilicate, microtensile bond strength, resin cement, zirconia reinforced lithium silicate
