ABSTRACT
OBJECTIVE: The aim of this study is to determine the reactive forces of Leaf Expanders during expansion in invitro environment.
MATERIALS AND METHOD: In this study, 4 types of Leaf Expansion screws, 450 g-6 mm, 900 g-6mm, 450 g-9 mm and 900 g-9 mm, were used. The forces applied by these
screws to the jaw depending on the amount of opening (elongation) were measured with a small-sized force measuring device designed specially for this study. The
force produced by each screw was determined depending on the opening distance. The force created by the appliance in the load cell was measured with the load cell
by moving the micrometer 0.01 mm at each step. These forces were recorded in a software program and graphs were created showing the changes in force-depending on
the amount of opening.
RESULTS: The forces produced by the Leaf Expansion appliances were measured as 422.7 ± 94.1 g, 778.5 ± 142.2 g, 421.1 ± 53.8 g and 851.4 ± 146.8 g, respectively.
CONCLUSION: The forces measured in all Leaf Expansion screws tested were close to the nominal force values reported by the company and were within acceptable
limits.

AMAÇ: Bu çalışmanın amacı, in-vitro ortamdaki genişletme esnasında Leaf Ekspansiyon vidalarının oluşturduğu reaktif kuvvetleri belirlemektir.
GEREÇ VE YÖNTEM: Çalışmada 450 g-6 mm, 900 g-6mm, 450 g-9 mm ve 900 g-9 mm olmak üzere 4 çeşit Leaf Ekspansiyon vidası kullanılmıştır. Bu vidaların açılma (uzama)
miktarına bağlı olarak çeneye uyguladığı kuvvetler çalışmaya özgü olarak tasarlanarak üretilen küçük boyutlu bir kuvvet ölçüm cihazı ile ölçülmüştür. Her bir vidanın ürettiği
kuvvet açılma mesafesine bağlı olarak belirlenmiştir. Mikrometre her adımda 0.01 mm hareket ettirilerek apareyin yük hücresinde oluşturduğu kuvvet bir yük hücresi
yardımıyla ölçülmüştür. Bu kuvvetler bir yazılım programında kayıt altına alınmış ve kuvvetin açılma miktarına bağlı değişimini veren grafikler oluşturulmuştur.
BULGULAR: 450 g-6 mm, 900 g-6 mm, 450 g-9 mm ve 900 g-9 mm Leaf Ekspansiyon apareylerinin oluşturduğu kuvvetler sırasıyla 422.7 ± 94.1 g, 778.5 ± 142.2 g, 421.1 ± 53.8 g
ve 851.4 ± 146.8 g olarak ölçülmüştür.
SONUÇ: Test edilen tüm Leaf Ekspansiyon vidalarında ölçülen kuvvetler, firmanın belirtiği nominal kuvvet değerlerine yakın ve kabul edilebilir sınırlar içeresinde bulunmuştur.
