Bulgular: Beş model arasında, kemikte
görülen en yüksek Von Mises Stres değeri, tek taraflı kusurlu (1/3 kusurlu)
maksillada bulundu. Deformasyon değeri 2/3 kusurlu maksilla modelinde en yüksek
bulundu. Asimetrik defekt modellerinde, maksilla'nın sağlam kısmında daha
yüksek stres değerleri elde edildi. Simetrik kusurlu modellerde, stresin daha
homojen bir şekilde dağıldığı görüldü.

Evaluation of Biomechanical Effects of Quad Zigomatic Implant Applications in Four Different Maxillary Defect Types

 

Abstract

 

Purpose:
The
purpose of this study is to evaluate the biomechanical effects of quad
zygomatic implant use in four different type alveolar defected maxilla.

Materials
and Methods: Three
dimensional models of human skull, zygomatic implants, bar attachment and
hybrid prosthesis was modeled using SolidWorks Computer-Aided Design (CAD)
program. Four different defect locations were modeled on intact model to mimic
different alveolar defect scenarios. In all models, four zygomatic implants were
placed on maxilla models at the location of first premolar and second premolar
tooth, assembly of the modeled parts were completed.  The data were processed by ANSYS Workbench
software, 150N vertical occlusal and 300N masseteric load were simulated on
modeled prosthesis. The Maximum Von Mises Stress in bone/implants and
deformations were visualized and comparatively evaluated with color
distribution scale.

Conclusion:  Cortical bone thickness, defect size and localization are among the
factors closely related to the stability and success of the implant.
