Purpose: The present study was aimed to evaluate the bone height changes around abutments with two different framework materials for extracoronal attachment mandibular bilateral distally extension removable partial denture (RPD) and compare patient satisfaction associated with its use. Materials and methods: Ten partially edentulous patients (long span kennedy class I) were selected, for all patients splinting of remaining abutment were done by porcelain fused to metal bridges, after cementation the RPD frameworks were digitally designed by CAD software and printed into 3-D resin pattern after intra-oral try in of these patterns, the patients were divided into two equalized groups, the patients in first group received extracoronal attachment (RPD)with from milled PEEK (Juvora) framework. While patients in second group received extracoronal attachment (RPD) with conventional metal framework by lost wax technique. Digital radiography was used for bone height assessment of distal abutment at time of prosthesis insertion, 6 and 12 months later. Patient satisfaction was measured using VAS scale.
