Bulgular: Beş model arasında, kemiktegörülen en yüksek Von Mises Stres değeri, tek taraflı kusurlu (1/3 kusurlu)maksillada bulundu. Deformasyon değeri 2/3 kusurlu maksilla modelinde en yüksekbulundu. Asimetrik defekt modellerinde, maksilla'nın sağlam kısmında dahayüksek stres değerleri elde edildi. Simetrik kusurlu modellerde, stresin dahahomojen bir şekilde dağıldığı görüldü.AnahtarKelimeler:Zigomatik implant, kuad zigoma, maksillar defekt, sonlu elemanlar analiziEvaluation of Biomechanical Effects of Quad Zigomatic Implant Applications in Four Different Maxillary Defect Types Abstract Purpose:Thepurpose of this study is to evaluate the biomechanical effects of quadzygomatic implant use in four different type alveolar defected maxilla.Materialsand Methods: Threedimensional models of human skull, zygomatic implants, bar attachment andhybrid prosthesis was modeled using SolidWorks Computer-Aided Design (CAD)program. Four different defect locations were modeled on intact model to mimicdifferent alveolar defect scenarios. In all models, four zygomatic implants wereplaced on maxilla models at the location of first premolar and second premolartooth, assembly of the modeled parts were completed.  The data were processed by ANSYS Workbenchsoftware, 150N vertical occlusal and 300N masseteric load were simulated onmodeled prosthesis. The Maximum Von Mises Stress in bone/implants anddeformations were visualized and comparatively evaluated with colordistribution scale.Conclusion:  Cortical bone thickness, defect size and localization are among thefactors closely related to the stability and success of the implant.Keywords:Zygomatic implant, quadrant zygoma, maxillary defect, finite element analysis
