Outline of Final Research Achievements |
The purpose of this study was to investigate the effects of clip materials and numbers for bar attachments on the stress applied to maxillary implant overdentures(IODs) without palatal coverage. This study included finite element analysis and an edentulous maxillary model study with strain gauges. Accordingly, regardless of clip numbers, it was concluded that the stress around plastic clips tended to be lower than that around metal clips. This finding can be a hint of solutions for frequent fractures of maxillary IODs.
