Farklı Teknikler ile Hazırlanan Metal Alt Yapılar ile Porselen Arasındaki Bağlanma Dayanımına Yaşlandırma Sürelerinin Etkisi

The effect of aging times on the bond strength between metal substructures prepared with different techniques and porcelain ABSTRACT Aim: This study was carried out to examine the effect of aging times on the bond strength between metal substructures prepared with different techniques and porcelain. Materials and Methods: İn the study; Superstructure porcelain was applied to a total of 80 Cr-Co metal substructures prepared with casting, milling, DMLS (Direct Metal Laser Sintering) and SLM (Selective Laser Melting) techniques..After the control group samples were separated, the other samples were subjected to aging at different times (1000, 3000, 5000) and their bond strength was evaluated. After the control group samples were separated, other samples were subjected to aging process at different times (1000, 3000, 5000). The data obtained were compared using two-way analysis of variance and Tukey multiple comparison test. Results: Metal substructure production techniques and aging times were statistically significant (p <0.01). Discussion: The data obtained in this study showed that the casting method in the preparation of metal and metal-based restorations is still one of the most valid production methods due to the predictable results. Key Words: Metal substructure preparation techniques, aging times, porcelain, bond strength
