Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
CAD PEEK frame-work
Construction of PEEK framework will be done conventionally by lost wax technique using a vacuum press device. The wax pattern will be invested in a mold using special investment. Then it will be heated and melted to produce a mold into which PEEK will be vacuum pressed. The framework will be fitted on the master cast

Then it will be heated and melted to produce a mold into which PEEK will be vacuum pressed. The framework will be fitted on the master cast
CAD metallic frame-work
A metallic framework will be obtained using the conventional lost wax technique and casting. After de-investing, finishing and polishing, the framework will be fitted on the master cast. Intraoral try in of the framework will be done followed by bite registration record. The next step will be teeth setting and try in. Heat cured acrylic resin denture base will be processed, finished and polished conventionally. The finished removable partial denture will then be checked intraorally for any needed modifications and finally delivered.
