The Aim of the Study Will be Clinically and Radio Graphically Comparison of Two Implant Designs Used to Treat Atrophied Mandible . Implant Design Comparison Will Done for Implant Stability,Peri-implant Soft Tissue Health Changes and Bone Changes .Patients Will be Divided Randomly Into Two Group

Resumen breve

The aim of the present study will be clinical and radio graphical comparison of four basal and compressive implant designs will be installed in the interforamina area of atrophied edentulous mandible and immediately loaded by screw retained mandibular overdenture . Implant design comparison will be done clinically and radiographically after one and two years of implant loading
