Özet
AMAÇ: Ortodontik kuvvet elemanlarindan nikel-titanyum kapali yaylarin, elastomerik zincirlerin ve aktif tie- backlerin zamana göre kuvvet kayiplarinin yapay tükürük içeren in vitro ortamda karsilastirmaktir.GEREÇ VE YÖNTEM: Çalismada 3 farkli markadan elastomerik zincirler, Ni-Ti kapali yaylar ve aktif tie-backler 9 gruba ayrildi. Örneklerin yapay tükürük içeren in vitro ortamda zamana bagli kuvvet kayip yüzdeleri karsilastirildi. Kuvvet degerleri baslangiçta, 1. saatte, 24. saatte, 7. günde, 21. günde ve 28. günde ölçüldü ve kaydedildi. Elde edilen veriler Kolmogorov-Smirnov, Kruskal Wallis, Mann- Whitney U ve Wilcoxon testleri ile istatistiksel analize tabi tutuldu. Anlamlilik degeri p<0.05 olarak kabul edildi.BULGULAR: Baslangiçta en fazla ve en az kuvvetler sirasiyla elastomerik zincirlerde ve nikel-titanyum kapali yaylarda ölçüldü (p<0.05). 24. saatte yapilan ölçümlerde elastomerik zincirler, nikel-titanyum kapali yaylar ve aktif tie-back’ler arasinda anlamli farklilik bulunmadi (p>0.05). 28. günde tüm gruplarda anlamli kuvvet kayiplari ölçülse de, aktif tie-backlerde elastomerik zincirlere göre markadan bagimsiz olarak anlamli sekilde daha az kuvvet kaybi ölçüldü (p<0.05). 28. günde en az ve fazla kuvvetler sirasiyla elastomerik zincirlerde ve Ni-Ti kapali yaylarda ölçüldü (p<0.05).SONUÇ: Ortodontik bosluk kapatma mekaniklerinden, nikel-titanyum kapali yaylar en stabil olmak üzere, aktif tie-backlerin elastomerik zincirlere göre daha stabil bir kuvvet uyguladigi dolayisiyla kullanilan kuvvet elemani tipinin kuvvet kaybi düzeyinde temel belirteç oldugu görüldü.
OBJECTIVE: This study aims to compare the force losses of nickel-titanium closed springs, elastomeric chains, and active tie-backs over time in an in vitro environment containing artificial saliva.MATERIALS AND METHODS: In the study, elastomeric chains, nickel-titanium closed springs, and active tie-backs from 3 different brands were divided into 9 groups. The percentages of force loss in the samples over time were compared in the in vitro environment containing artificial saliva. Force values were measured and recorded at initial activation, 1st hour, 24th hour, 7th day, 21st day, and 28th day. Statistical analysis of the data were performed with Kolmogorov-Smirnov, Kruskal Wallis, Mann-Whitney U, and Wilcoxon tests. The significance value was considered as p<0.05.RESULTS: The highest and lowest forces at the initial activation hour were measured in elastomeric chains and nickel-titanium closed springs, respectively (p<0.05). There was no significant difference between elastomeric chains, nickel-titanium closed springs, and active tie-backs in the measurements performed at the 24th hour (p>0.05). Although significant force losses were measured in all groups on the 28th day, active tie-backs lost significantly less force than elastomeric chains, regardless of brand. On the 28th day, the lowest and highest forces were measured in elastomeric chains and nickel-titanium closed springs, respectively (p<0.05).CONCLUSIONS: Among the orthodontic space closure mechanics, nickel-titanium closed springs were the most stable; however, active tie-backs produced a more stable force than elastomeric chains, so the type of force element used was the main indicator of the force loss level.
