Arm && Interventions

Group	Intervention	Description
cobalt-chromium framework partial dentures	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.
PEEK framework partial dentures	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.

Primary Outcome Measures

Name	Time	Method
Periodontal status	Change in periodontal status will be assessed at base line , after one month and after 3 months .	periodontal status of the abutment teeth assessed by a periodontal chart .
