DENTAL İMPLANTIN İMMEDİAT YÜKLENMESİNDE İKİ FARKLI KEMİK GREFTİNİN SONLU ELEMANLAR ANALİZ YÖNTEMİNE GÖRE KARŞILAŞTIRILMASI

Öz

Amaç: Çalışmanın amacı, üç boyutlu (3D) sonlu elemanlar analiz yöntemi kullanılarak yeni bir sentetik kemik grefti olan TiO2 ile sığır kaynaklı Cerabone greft materyalleri üzerindeki stresleri değerlendirmektir. Yöntemler: Dental implant maksillaya yerleştirildikten sonra, 2 ayrı defekt modeli (2 mm dikey 2 mm yatay defekt ve 3 mm dikey 3 mm yatay defekt) yukarıda belirtilen kemik greftleriyle desteklendi. Modelleme için dental implant, abutment ve kemik grefti kullanıldı. Sanal ortamda iki farklı greftin stres dağılımını karşılaştırmak için maksilla modeli, implant modeli ve kemik greft modeli üç boyutlu olarak oluşturuldu. Modeller üzerinde Sonlu Elemanlar Analizi yapıldı ve sonuçlara göre stres dağılım özellikleri değerlendirildi. Sonuçlar: 3D Sonlu Elemanlar Analiz Yöntemine göre sentetik kemik grefti TiO2 ile sığır kaynaklı Cerabone arasında stres dağılımı açısından bir fark yoktur. Sonuç: Greft yerleştirilmediğinde implant üzerindeki stresin azaldığı bulunmuştur. Mümkünse, greftlemeden doğrudan implant uygulamak stres dağılımı açısından daha avantajlıdır.

COMPARISON OF TWO DIFFERENT BONE GRAFTS TO IMMEDIATE LOADING OF DENTAL IMPLANT WITH FINITE ELEMENT ANALYSIS METHOD

Öz

Purpose: The aim of study, to evaluate the stresses on bovine sourced Cerabone graft materials with a new synthetic bone graft, TiO2, by using a three dimensional (3D) finite element analysis method. Methods: After the dental implant was placed in the maxilla, 2 separate defect models (2 mm vertical 2 mm horizontal defect and 3 mm vertical 3 mm horizontol defect) were supported with the above-mentioned bone grafts. Dental implants, abutments and bone grafts are used for modeling. In order to compare the stress distribution of two different grafts in a virtual environment, the maxilla model, implant model and bone graft model were created in three dimensions. Finite Element Analysis was performed on the models and their stress distribution properties were evaluated according to the results. Results: There is no difference between the synthetic bone graft TiO2 and bovine sourced Cerabone in terms of stress distribution according to the 3D Finite Element Analysis Method. Conclusion: It has been found that the stress on the implant is reduced when the graft is not placed. If possible, applying implants directly without grafting is more advantageous in terms of stress distribution.
