ABSTRACT

 Aim: The purpose of this study is to compare the stress formations of two different implant designs in augmented maxillary sinuses using the three-dimensional (3D) finite elements analysis method.  

Material and Methods: A 3D model of atrophic posterior maxilla involving the maxillary sinus was created with computer software by using a computerized tomography image of a real patient. Similarly, implants in two different designs, prosthetic superstructures, and graft applied maxillary sinus were simulated. Four groups were obtained in total with two types of implants (Ankyos: A, Xive: X) with different designs, and two different scenerarios including control models (A1 and X1) without maxillary sinuses and maxilla models with grafted maxillary sinuses (A2 and X2). In these groups, stress analysis on cortical bone, trabecular bone and graft material were conducted under the forces close to real masticatory forces. 

Results: Tension-type stresses in cortical bone as a result of vertical loading, was lower in X Groups. When control group models were compared with maxillar sinus augmentation (MSA) models, no significant difference was revealed. In trabecular bone and graft material, no significant difference was revealed except for the A2 model which generated lower stresses. Compression-type stresses in cortical bone as a result of vertical loading, less stress formation was observed in Group A models. When MSA models were compared, X2 group caused more stress formation. In control groups the results were similar. In trabecular bone and graft material, no significant difference was found. Tension-type stresses in cortical bone as a result of oblique loading, no significant differences were revealed. In trabecular bone and graft material, in all models, Group A caused significantly less stress. Compression-type stresses in cortical bone as a result of oblique loading, significantly less stress formation was measured in Group A models. When MSA models were compared, the implant in the X2 group led to more stress formation. In the control groups, the results were similar. In the tension-type stresses in trabecular bone and graft material, no significant difference was revealed except for the A2 model which led to less stress. The stress values formed on the graft material were quite close.  

Conclusion: Implant design with “V” shaped thread (Group X) caused more stress formation in almost all conditions, except vertical compression stresses caused by vertical loadings, in comparison to the models with square shaped thread form implants (Group A).

OGMENTE MAKSİLLER SİNUS BÖLGESİNE UYGULANAN IKI FARKLI IMPLANT TASARIMININ OLUŞTURDUĞU STRESLERIN BIYOMEKANIK OLARAK KARŞILAŞTIRILMASI

ÖZ

Amaç: Bu çalışmanın amacı 3 boyutlu (3D) sonlu elemanlar stres analizi yöntemini kullanarak, posterior maksiller bölgede greft kullanılarak sinüs tabanı yükseltilmesi yapılmış örneklerde iki farklı implant tasarımının stres oluşumuna etkilerini karşılaştırmaktır.

Gereç Ve Yöntem: Gerçek bir hastaya ait bilgisayarlı tomografi görüntüsü kullanılarak maksiller sinüsü de içeren atrofik posterior maksillanın 3D modeli bilgisayar yazılımları ile oluşturulmuştur. Benzer şekilde iki farklı tasarımda implant modelleri, protetik üst yapılar ve maksiller sinüse uygulanmak üzere greft materyali canlandırılmıştır. Farklı tasarıma sahip iki tip implant (Ankyos: A, Xive: X), maksiller sinüsün ihmal edildiği kontrol modellerine (A1 ve X1) ve içerisine greft materyali yerleştirilen sinuse sahip maksilla modellerine yerleştirilerek (A2 ve X2) toplamda 4 grup elde edilmiştir. Oluşturulan bu gruplarda, teknik olanakların elverdiği ölçüde gerçek yaşamdaki çiğneme kuvvetlerine benzer kuvvetler altında kortikal, trabeküler ve greft materyali üzerinde oluşan streslerin analizi yapılmıştır.  

Bulgular: Vertikal kuvvetler karşısında kortikal kemikte oluşan gerilme stresleri X gruplarında daha düşük bulunmuştur. Kontrol grupları ile sinus ogmentasyonu (SO) grupları karşılaştırıldığında anlamlı bir fark oluşmamıştır. Trabekuler kemik ve greft materyalinde daha düşük stress oluşturan A2 modeli hariç diğer modellerde anlamlı fark oluşmamıştır. Vertikal kuvvetlere karşı oluşan sıkışma streslerinde, kortikal kemikte A gruplarında daha düşük stresler ölçülmüştür. SO gruplarında X2 modelinde daha yüksek stress oluşmuştur. Kontrol gruplarında ise fark gözlenmemiştir. Trabeküler kemik ve greft materyalinde ise bir fark gözlenmemiştir. Oblik kuvvetler sonucu oluşan gerilme steslerinde, kortikal kemikte bir fark bulunamamıştır. Trabeküler kemik ve greft materyalinde ise A grubunda düşük stress değeleri oluşmuştur. Oblik kuvvetlere karşı oluşan sıkışma tipi streslerde, kortikal kemikte A gruplarında düşük stresler gözlenmiştir. SO gruplarında X2 modeli daha yüksek stress oluşturmuştur. Kontrol grupları arasında ise fark bulunamamıştır. Oblik kuvvetlere karşı oluşan gerilme streslerinde, trabeküler kemik ve greft materyalinde, daha düşük stresler oluşan A2 modeli haricinde fark gözlenmemiştir.       

Sonuç: Üçgen yiv tasarımlı implantlara (Grup X) sahip modellerde, kare yiv tasarımında implantlara (Grup A) sahip modellere göre, vertikal kuvvetler sonucu oluşan sıkışma stresleri dışında, neredeyse her koşulda daha fazla stres oluşumu gözlenmiştir.
