Outline of Final Research Achievements

The purpose of this study was to investigate the biomechanical behavior of immediately loaded implants in an edentulous mandible according to the All-on-Four concept.The results showed that mandibular fixed full-arch prostheses without cantilevers may result in a favorable reduction of the peri-implant bone strain during the healing period, compared with cantilevers.The maximum micromotion was within the acceptable limits for uneventful implant osseointegration according to the All-on-Four concept.Framework material did not play an important role in reducing the peri-implant bone strain and micromotion at the bone-implant interface.
