Abstract

Objectives: To evaluate stress distribution around dental implants in the areas of the canine region (CR) and the secondincisor region (SIR) of the mandible in implant-supported prostheses by 3-dimensional finite analysis (FEA).Methods: The cadaveric mandible and the Ti-6Al -4V implant with 4.0 diameter 10 mm length were performed in 3-Dscanning and modelled. After transferred to the FEA program (Ansys 13), four variations were analyzed to representdifferences in implant location (i.e., SIR or CR) with two vertical loading forces were applied to the midline (60 N) andposterior line (100 N) of a bar placed between implants. The von Mises and Principal stresses were evaluated by FEA.Results: Von Mises stress analysis values are model 1: 2.7 MPa; model 2: 2.21 MPa; model 3: 9 MPa; model 4: 7.3MPa and maximum-minimum Principal stress values are model 1: 0.03 MPa, -2.23 MPa; model 2: 0.07 MPa, -2.37MPa; model 3: 0.013 MPa, -4.59; model 4: 0.016 MPa, -5.18 MPa.Conclusion: Von Mises and Principal stress values obtained as a result of finite element analysis were found similar in4 different models. There is no difference in clinically

Özet

Amaç: İmplant destekli hareketli protez hastalarında kanin bölgesi (CR) veya lateral diş bölgesine (SIR) yerleştirilen implantlarda oluşan streslerin sonlu elemanlar analizi ile değerlendirilmesi. Gereç ve Yöntem: Kadavra mandibulası ve 4.0 10 mm’lik Ti–6Al–4V implantın 3 boyutlu taraması yapılarak bilgisayar ortamında modellemesi yapıldı. ANSYS 13 programına aktarılan modellerin, implant lokalizasyonu kanin diş veya lateral diş bölgesi olmak üzere her modelde posterior birinci molar bölgesine 100 N veya anterior bölgede barın orta noktasına 60 N uygulanması ile toplam 4 farklı model analizi gerçekleştirildi. İmplantlarda meydana gelen von Mises ve Principal stres değerleri ilgili programda analiz edildi. Bulgular: Von Mises stres analizi değerleri model 1: 2.7 MPa; model 2: 2,21 MPa; model 3: 9 MPa; model 4: 7.3 MPa ve maksimum-minimum Principal stres değerleri model 1: 0.03 MPa, -2.23 MPa; model 2: 0,07 MPa, -2,37 MPa; model 3: 0,013 MPa, -4,59; model 4: 0,016 MPa, -5,18 MPa olarak belirtilmiştir. Sonuç: Sonlu elemanlar analizi çalışması sonucu elde edilen von Mises ve Principal stres değerleri 4 farklı modelde benzer bulunmuştur. Klinik olarak bir önemi yoktur.
