Özet
Background > To evaluate 4 different composite resins in terms of aligner attachment accuracy and surface roughness. Material and methods > 160 premolars were divided into 4 groups (n = 40): Group 1: GC Aligner Connect (TM); 2: GC Ortho Connect (TM); 3: 3M ESPE Filtek (TM) Z350 XT flowable; 4: 3M ESPE Filtek (TM) Z350 XT Universal. Each group was divided into 2 equal subgroups regarding curing irradiances (Power of 1000 mW/cm(2) in subgroup A for 10 s, and 3200 mW/cm(2 )in B for 3 s, VALO (TM) Cordless-LED Curing Light). The primary objective was to compare the realized attachments with those of the virtual with 3D Geomagic software. A contact surface profiler was used for roughness measurement (Ra) as the secondary aim. The data were analysed using the IBM SPSS 25.0. The significance level was set at p < 0.05. Results > In subgroup A, the mean "excess" accuracy measurement of the 3M ESPE Filtek TM Z350 XT flowable resin was found to be higher than others. In subgroup B, the "excess" accuracy measurements of the 3M ESPE Filtek(TM ) Z350 XT flowable (0.24 +/- 0.07 mm) and Universal (0.26 +/- 0.05 mm) resins were significantly higher than those of the GC Aligner Connect(TM )resin (0.17 +/- 0.06 mm), (p < 0.05). According to the Ra measurements in subgroup A, the measurement of the GC Aligner Connect(TM )(1.75 +/- 1.09
