Zusammenfassung:The prosthetic rehabilitation of edentulous maxillary arches is a challenging procedure. When an implant retained prosthesis is considered, more satisfactory results can be obtained but the anatomy and the bone quality of the maxilla limits the usege of dental implants in in edentulous maxilla and necessiates advanced surgical procedures. The use of tuber implants are becoming increasingly in comprehensive restorative procedures. There are limited numbers of studies on tuber implants, many of which have examined either the success and/or survival rate of implants or discussed the surgical difficulties of them. None of them have evaluated the biomechanical factors related to implant tilting. this study is designed to examine in-vitro the magnitude and character of the loads acting on the tilted implants in the tuberosity region. An anatomical 3-D finite element model of an atrophied maxilla was constructed. The implants were placed with different angles. Horizontal and vertical loads were applied. According to the results of this study, the tuberosty area can be used for implant placement. The results of this numerical study coincided with the results of clinical studies.
