Özet:

 In this study, we aimed to analyze the maximum insertion torque, pull-out and shear strength of the samebrand mini screws with different body structures that were inserted at 30,45,60and, 90 in order to compare their stability. The study consisted of 144 self-drilling, 1.48 mm titanium alloy minis crews Abso-Anchor conical, Abso-Anchor cylindrical. Each group of mini screws were inserted in fresh male bovine hip bone segments at four different angles and the maximum insertion torque was recorded. Pull-out and shear force resistance values were measured and recorded until 1.5 mm displacement occurred. The data was analyzed with the use of the IBM SPSS program. Statistical analyses were conducted with Shapiro-Wilk, One-Way ANOVA, Tukey HSD and Students t-test. It was determined that the maximum insertion torque and force resistance values of the conical mini screws and an insertion angle of 45 were significantly higher than those of the other groups. The Abso-Anchor conical group was the most resistant to failure. To achieve the best primary stability, the use of aconical shape is advisable. The insertion angle of 45 is more favorable than excessive oblique or vertical angles.

 Çalışmanın amacı 30, 45, 60 ve 90 de yerleştirilmiş, aynı markanın farklı gövde yapısına sahip mini vidalarının maksimum yerleştirme torkunu, pull-out ve shear kuvvet dayanımını ölçmek ve stabilitelerini karşılaştırmaktır. Çalışmada 1.48 mm ebatlarında toplamda 144 tane titanyumalaşım, self-drilling mini vida Abso-Anchor konik, Abso-Anchor silindirik kullanılmıştır. Her iki grup dört farklı açıda yerleştirilmiş ve maksimum yerleştirme torkları kaydedilmiştir. Daha sonra vidalara pull-out ve shear kuvvet testleri, vida başı 1.5 mm yer değiştirinceye kadar uygulanmış ve gösterdikleri kuvvet dayanımları Ncm cinsinden kaydedilmiştir. Veriler IBM SPSS programıyla analiz edilmiştir. İstatistiksel analizler; Shapiro-Wilk, tek yönlü Anova, Tukey HDS ve Student t testleriyle yapılmıştır. En fazla maksimum yerleştirme tork değeri ve kuvvet dayanımı, konik gövde yapısı ve 45 yerleştirme açısında görülmüştür. Abso-Anchor konik grubu primer stabilite yönünden diğer gruptan daha başarılı bulunmuştur. En yüksek primer stabilite için konik gövde yapısı tavsiye edilmektedir. 45 yerleştirme açısı, aşırı eğimli veya dik açılara göre daha uygundur.
