This study is aiming to evaluate the biting force of polyetheretherketone (PEEK) framework partial dentures compared to that of cobalt-chromium ones in mandibular Kennedy class I edentulous cases hoping that polyetheretherketone (PEEK) framework removable partial dentures can improve the patient masticatory efficiency .

Polymer-based framework recently introduced made of polyetheretherketone polymer frame combined with acrylic resin denture teeth and a conventional acrylic resin denture base.
It's a bio-compatible metal used in thin sections so less bulky, provide high strength and stiffness ,conduct heat and cold for a more natural experience, enable designs that minimize the covering of the gingival margins, allow for a stable denture base, and resistance to corrosion.Drawbacks of metal frameworks can include hypersensitivity, aesthetics because of metal metal display, oral galvanism, adverse tissue reactions, osteolysis of abutment teeth, and biofilm production

Biting force
Biting force of the patient wearing the removable partial denture measured by I-load sensor device.
Time frame: Change in baseline biting force from time of insertion, insertion after 1 month and after 3 months
