This study was carried out on twenty patients having edentulous maxillary jaw against mandibular jaw which had two retained teeth one on each side. The patients were divided into two groups.
group A an overdenture retained with flexi-post [resilient] attachment was constructed while for B an overdenture retained by post and core [rigid] was constructed. These two types of overdentures were studied by evaluating their effects on alveolar bone, residual ridge and on the electromyographic activity of masseter muscle. All these examination were done at the time of insertion, after 6 months and after one year. The results of this work showed no significant difference between the two groups in all readings
