Amaç:
Elastomerik zincirlerin klinik kullanımı sırasında birçok avantajlarının olmasının yanısıra aktivasyon kuvvetinin zamanla farkedilir bir şekilde azalması en büyük dezavantajlarından biridir. Bu çalışmanın amacı; farklı elastomerik zincirlerde zamanla oluşan kuvvet kaybındaki değişimlerin incelenmesidir.

Gereç ve Yöntem:
Çalışmamız, 5 farklı elastomerik zincir grubundan oluşmuştur; Grup 1: American Orthodontics (Memory chain), Grup 2: Rocky Mountain Orthodontics (Elastomeric chain), Grup 3: 3M (Alastik chain), Grup 4: American Orthodontics (Plastik chain), Grup 5: Opal (Opalastic chain). Örnekler yapay tükrük dolu bir kabın içerisine daldırılarak 37.1°C'deki inkübasyon makinasında bekletildi. İlk aktivasyon sonrası 0.saat, 4.saat, 8.saat, 24. saat ve 48.saat sonra olmak üzere 5 kez gerilme direnci ölçümü yapılmıştır. Gruplar arası karşılaştırmalar ve grup içi zamana göre değişimler Kruskall-Wallis H ve Fridman testi ile incelenmiştir.

Bulgular:
8., 24. ve 48. saatte ölçülen gerilme direnci değerleri arasında tüm gruplarda anlamlı farklılık bulunmuştur. AOM elastomerik grubu 3M, AO ve Opal gruplarına göre daha düşük kuvvet kaybı değerleri göstermiştir (p<0.05), RMO grubu ile arasında istatistiksel olarak anlamlı bir fark bulunamamıştır.

Sonuç:
Karşılaştırılan tüm elastomerik zincir gruplarında zamanla kuvvet kaybı artmıştır ancak ilk gün özellikle ilk 8 saatte oldukça dikkat çekici kuvvet kaybı olmuştur. Sırasıyla AOM, RMO ve 3M grubu en düşük kuvvet kaybı değerlerini gösteren elastomerik zincir grupları olmuştur.

Aim:
In addition to the many advantages of elastomeric chains during clinical use, one of the biggest disadvantages is that the activation force decay noticeably over time. The aim of this study; evaluation of the change in mechanical force decay over time in different elastomeric chains.

Material and Method:
This study group; consists of a total of 5 different elastomeric chain groups; American Orthodontics (Memory chain), Rocky Mountain Orthodontics (Elastomeric chain), 3M (Alastik chain), American Orthodontics (Plastic chain), Opal (Opalastic chain). The samples were immersed in a container filled with artificial saliva and kept in the incubation machine at 37.1°C.After first activation, tensile strength measurements were made 5 times, at 0 hour, 4 hours, 8 hours, 24 hours and 48 hours. Comparisons between groups and changes with respect to time within groups were examined by Kruskall-Wallis H and Fridman test.

Results:
There was a significant difference between the tensile strength values measured at the 8th, 24th and 48th hours in all groups. AOM elastomeric group showed lower strength loss values compared to 3M, AO and Opal groups (p<0.05) and no statistically significant difference was found between the RMO group.

Conclusion:
In all compared elastomeric chain groups, the force decay increased over time, but there was a remarkable force decay on the first day, especially in the first 8 hours. AOM, RMO and 3M groups were the elastomeric chain groups showing the lowest force decay values, respectively.
