COMPARISON OF SHORT DENTAL IMPLANTS UNDER DIFFERENT LOADING CONDITIONS AND LOCATIONS

Öz

Dental implant restoration has been widely accepted as one of the treatment modalities to replace missing teeth and to restore human masticatory function. The finite element method (FEM) has been a useful tool in studying the bone-to-implant interface under mechanical loading. The use of short dental implants are increased thanks to its advantages according to long dental implants when the quality of bone is lower. The aim of this study was to analyse the effects of implant diameter, length and loading conditions on short dental implants. A three dimensional (3D) model of short dental implants were made with different sizes and types. Dental implant designs were performed on Solidworks 2013. The mandible model is obtained from Computed Tomography then transferred to 3D model. Finite Element analysis is done by applying material properties, contact properties, physiological loading and boundary conditions with the use of Ansys Workbench

FARKLI YÜKLEME ŞARTLARI VE YERLEŞİMLERDE KISA DENTAL İMPLANTLARIN KARŞILAŞTIRILMASI

Öz

Dental implant restorasyonu, eksik dişlerin yerini dolduracak ve insan çiğneme fonksiyonunun yeniden kazanılmasını sağlayacak en yaygın tedavi yöntemlerinden biri olarak kabul edilmiştir. Sonlu elemanlar yöntemi (FEM) mekanik yük altında kemik-implant arayüz çalışmalarında yararlı bir araç olmuştur. Kısa dental implantların kullanımı, kemiğin kalitesi düşük olduğunda uzun dental implantlara göre daha avantajlı olduğu için artmıştır. Bu çalışma, kısa dental implantlarda implant çapı, uzunluğu ve yükleme koşullarının etkilerinin görülmesi amacıyla gerçekleştirilmiştir. Kısa dental implantların üç boyutlu (3D) modeli farklı boyutlarda ve farklı dizaynlarda yapılmıştır. Dental implantların tasarımları Solidworks 2013 programıyla oluşturulmuştur. Üç boyutlu çene kemiği modeli bilgisayarlı tomografiyle elde edilmiştir. Sonlu eleman analizleri ise malzeme özellikleri, temas özellikleri, fizyolojik yükleme ve sınır şartları girilerek Ansys Workbench programıyla yapılmıştır.
