“…Pull-out strength increased significantly when cortical bone thickness doubled from 0.5 to 1.0 mm, but in young adolescents, who make up the majority of patients treated with orthopedics, the cortical thickness is sometimes less than 1 mm. 29 Thin cortical bone can cause stability issues because the stresses are localized mainly to the cortical bone region. Although we were only able to test the effects of force direction with our pull-out model, the test results using miniscrews at various insertion angles also advocate perpendicular insertion, 14 as do our FEM results.…”

“…In particular, the structure of the jawbone has been identified as an important factor contributing to the success or failure of implants. Farnsworth et al and Katranji et al carried out basic research on cortical bone thickness 21,22) . According to Miyamoto et al, the average thickness of cortical bone at implant insertion sites in the mandible is 2.22±0.47 mm, and their results suggested that the thicker the cortical bone, the greater the initial stability of the implant 23) .…”

“…70,71,73 David ve ark.nın, mini vidanın yerleştirildiği bölgelerde yaptığı kortikal kemik kalınlığı öl-çümlerinde; cinsiyet ile kortikal kemik kalınlığı arasında bir ilişki bulunamaz iken, erişkinlerde kortikal kemik kalınlığının adolesanlara kıyasla daha kalın olduğu bildirilmiştir. 74 Kortikal kemiğin yanı sıra, trabeküler kemik ve mini vida stabilitesi arasındaki ilişkinin değer-lendirildiği çalışmada; trabeküler kemik yoğunluğu ve kalınlığının da primer stabiliteyi etkilediği bildirilmiştir. 75 Kortikal kemiğin; yaşa ve mandibula ya da maksillada bulunduğu bölgeye göre farklılık göste-rebilmesi nedeni ile mini vida yerleştirilmeden önce vidanın yerleştirileceği alandaki kemik kalın-lığının ve yoğunluğunun "Cone Beam" bilgisayarlı tomografi ile değerlendirilmesinde fayda vardır.…”
