Prosthetic rehabilitation of the upper jaw in patients with expansive bone and soft tissue defects is still a significant problem lack of retantion and stability. Zygomatic implant is an alternative method for these patients. The purpose of this research was to evaluate the stress distribution in the zygomatic bone for three different implant-retained obturator prostheses configuration in a premaxillary with unilateral maxillary defect using a three dimensional finite element stress analysis. 3- dimensional finite element models were constructed based on computed tomograph data. Model 1; one zygomatic implant on defected side, two dental implant on nondefected side, model 2; two dental implant on nondefected side, model 3; one zygomatic implant on each side of the maxilla additionally one dental implant on non defected side. Bar attachments were used as superstructure. Vertical load 150 N was applied in three different ways and the stress distribution were observed and compared. In all loading conditions model 3 when compared another models, shows highest maximum principle stress value on zygomatic bone. Use of zygomatic implant with dental implant in the same part of the maxilla increased the stress values of the zygomatic bone |
