Summary

This clinical study will be done to compare between functional relining and digital altered cast of selective pressure impression techniques for constructing mandibular distal extension removable partial dentures using digitally fabricated frameworks by measuring the abutment alveolar bone height changes.

Detailed description

According to the functional impression techniques, all patients will be classified into two equal groups: Group A: Functional relining of processed RPD base at insertion: •After try in, a record base will be attached to the minor connectors and metal frameworks using 3D printed master cast.The finished removable partial denture is relined using the functional relining impression technique. Group B : Digitally obtained altered cast : Selective pressure impression technique will be made. Digital altered cast will be done according to J. Wu, Y. Cheng (20) as follow : All patients will be informed about the follow up and evaluation recalls. Evaluation of abutment alveolar bone height changes: Alveolar bone height changes of abutment teeth will be evaluated radiographically at insertion (T0), and after 6 (T6) \& 12 months (T12) after RPD insertion.
