Özet
Lazer sinterize yoluyla üretilen implant destekli kronların tutuculuklarında siman aralığının ve simanların etkisi Amaç: Bu çalışmanın amacı iki farklı siman aralığı ile yapılan implant destekli kronlar için kullanılan beş farklı simanın tutuculuk mukavemetini değerlendirmektir. Gereç ve Yöntemler: Standart titanyum dayanaklar dijital bir 3D lazer tarayıcı aracılığıyla tarandı. 100 standart metal alt yapı bir CAD/CAM sistem aracılığıyla iki farklı siman aralığı değerinde (20 ve 40 µm) tasarlandı. Alt yapılar beş farklı siman kullanılarak yapıştırıldı (n10). Poly F (PF), GC FujiCEM (GCF), Rely X (RX), MIS Crown Set(MCS) and Multilink N (MN). Örnekler 24 saat bekletildikten sonra 1000 devir termal siklus uygulandı. Termal siklustan sonra örnekler universal test cihazında 0.5 mm/dk. hızla çekme testine tabi tutuldu. Test sonuçları iki yönlü varyans analizini takiben tamhane testleri kullanılarak çoklu karşılaştırmalarla analiz edildi (?0.05). Bulgular: İstatistiksel analiz değerlendirildiğinde siman grupları arasında anlamlı farklılıklar görüldü (p0.05). PF ve MN sırasıyla en yüksek ve en düşük tutuculuk kuvveti ortalamasına sahipti. RX ve MCS arasında anlamlı farklılık bulunmadı. 20 den 40µm ye artan siman aralığı, her siman grubu için tutuculuğu anlamlı ölçüde arttırdı (p0.05). Sonuç: Çalışmada sunulan simanların klinisyenler için, implant dayanakların üzerine üretilen CAD/CAM metal alt yapılar için uygun siman seçimini belirlemede isteğe bağlı bir rehber olması amaçlanmıştır.
Effect of luting space and cements on retention of implant supported crowns fabricated by laser sintering Background: The aim of this study was to evaluate the retention strength of five different cements used for implant supported crowns with two cement gap values. Methods: Standard titanium abutments were scanned by means of a 3D digital laser scanner. 100 standard metal copings were designed by a CAD/CAM system with two cement gap values (20 and 40µm). The copings were cemented to the abutments using the following five cements (n10). Poly F (PF), GC FujiCEM (GCF), Rely X (RX), MIS Crown Set(MCS) and Multilink N (MN). The specimens were placed in 100% humudity for 24 hours then specimens were thermal cycled 1000 times. After thermal cycling specimens were subjected to a pull-out test using a universal testing machine at a 0.5 mm/min crosshead speed. The test results were analyzed with two-way ANOVA, followed by multiple comparisons using Tamhane tests (?0.05). Results: Statistical analysis revealed that significant differences were observed among cement groups (p0.05). PF and MN had the highest and the least mean retentive strength, respectively. No significant difference was found between RX and MCS. Increasing the cement gap from 20 to 40 µm improved retention significantly for each cement group (p0.05). Conclusion: The ranking of cements presented in the study is meant to be an arbitrary guide for the clinician in deciding the appropriate cement selection for CAD/CAM fabricated metal copings onto implant abutments.
