| Outline of Final Research Achievements |
The aim of this preliminary study is to compare patient-reported outcomes be- tween immediately and conventionally loaded mandibular two-implant overdentures retained by magnetic attachments. Nineteen participants with edentulous mandibles were randomly assigned into either an immediate loading group (immediate group) or a conventional loading group (conventional group). Each participant received 2 implants in the inter-foraminal region by means of flapless surgery. Prostheses in the immediate and conventional groups were loaded using magnetic attachments on the same day as implant placement or 3 months after surgery, respectively. The differences in median and 95% confidence interval between two groups were analyzed. In the lower denture domain of PDA, the immediate group showed a statistically higher score at 3 months (P = 0.04). This result indicate that immediate loaded implant overdentures are preferable to increase the patients reported outcomes.
