简要总结
This study is aiming to evaluate the periodontal status of the abutment teeth in Polyetheretherketone ( PEEK ) framework partial dentures compared with cobalt-chromium ones in mandibular kennedy class I edentulous cases aiming to preserve the optimum periodontal health of the abutment teeth .

研究组 & 干预措施
cobalt-chromium framework partial dentures
It's the gold standard biocompatible metal alloy used in thin sections, provide high strength and stiffness ,conduct heat and cold for a more natural experience, and is resistant to corrosion but their disadvantages include esthetic issues with metal display, oral galvanism, adverse tissue reactions,and osteolysis of abutment teeth.
干预措施: cobalt-chromium framework partial dentures (Device)
PEEK framework partial dentures
It's a promising polymer-based framework has recently been introduced which is made of polyetheretherketone polymer frame combined with acrylic resin denture teeth and a conventional acrylic resin denture base.
