The stress distributions in the bar attachments supported by implants which are placed in different angles

In this study, the stress distribution and values in the supporting bone of inclined implants splinted with bar attachments were investigated (evaluated) by finite element analysis method.In the present study, the dental implants placed in the interforaminal area were inclined and 10 different models were created. 90 N vertical and 180 N oblique loads were applied unilaterally to canines from both sides. Also, 150 N oblique load was applied to the incisors to simulate biting force. Maximum and minimum stress in the cortical bone was investigated in the Algor (Fempro, USA) programme.In all loading conditions, the highest maximum stress values were observed at the cortical bone around the neck of the implant. The principle stress values were higher in oblique loadings than in vertical loading conditions. The principle stress in the supporting bone, were effected by loading conditions and the direction of the loading. The ultimate attention shoukd be paid in order to orient the chewing forces along the long axis of the implant.
