Evaluation of Stress Distributions of Zirconia Connecting Screw in Bruxism:A Finite Element Analysis

Öz:
Background: The purpose of the present study was to evaluatethe stress distributions of zirconia or titanium connecting screwsunder different loads (vertical and oblique) in bruxism patientsand to indicate its applicability by comparing with physiologicalstress limit values. Methods: Four different models were created in which theimplants were the same size and design, with dental implant,abutment and connection screws made of zirconia or Ti (onlyscrew). 3D-Finite element analysis (3D-FEA) was applied tostudy the effect of a vertical load (1000 N) and oblique load (anangle of 30°) on abutments in the models. The placement ofimplants are mandibular right first molar. Computerizedtomography imaging of cadaver mandibles was used. Von Misesstresses of the different screw materials were compared witheach other and the physiological stress limit values for zirconia. Results: Von Mises stress values increased in oblique loading inall models. The von Mises stress values were significantlyreduced in the titanium screw than zirconium under both loadingsimulations. Conclusion: In patients with a high biting force physiologicalstress limit values for zirconia were not exceeded. Zirconconnection screw may be used in patients with bruxism.

Bruksizm Hastalarında Zirkon Bağlantı Vidasının StresDağılımlarının Sonlu Elemanlar Analizi İle Değerlendirilmesi

Öz:
Amaç: Çalışmanın amacı, bruksizm hastalarında farklımateryallerdeki implant-abutment bağlantı vidasında meydanagelen stress dağılımının değerlendirilmesidir. Ayrıca fizyolojik stresslimit değerleri ile karşılaştırılarak uygulanabilirliğini belirtmektir. Gereç ve Yöntemler: İmplantların, abutmentlerin ve bağlantıvidalarının aynı dizayn ve boyutta olduğu 4 model oluşturuldu.Bağlantı vidası titanium veya zircon olarak modellendi, diğermateryaller ise titanium olarak modellendi. Bruksizmli hastalarınısırma kuvvetinin taklidi için 1000 N dikey veya 30° açılı yüklemeabutmentlerin orta noktalarına uygulandı. Modellenen implant sağmandibular birinci molar hizasındadır. Mandibulanınmodellenmesinde kadavranın bilgisayarlı tomografi görüntülerikullanıldı. Farklı bağlantı vidası materyallerinde meydana gelen(zircon veya titanium) von Mises stress değerleri karşılaştırıldı.Ayrıca zirkonyum bağlantı vidasındaki von Mises stress değerlerizirkonyumun fizyolojik stress limit değeri ile karşılaştırıldı. Bulgular: Von Mises stres değerleri tüm modellerde 30° açılıyüklemede artmıştır. Von Mises stres değerleri, her iki yüklemesimülasyonunda titanyum vidada zirkonyuma göre önemli ölçüdeazaldı. Sonuç: Isırma kuvveti yüksek olan hastalarda zirkonyum fizyolojikstres limit değerleri aşılmamıştır. Bruksizm hastalarında zirkonbağlantı vidası kullanılmasında sakınca yoktur.
