Outcome Measures
Primary Outcomes (1)
Retention
retention force of RPD during attachment/detachment cycles measured by digital force meter device
change from baseline retention force after one month and after three months
Study Arms (2)
peek framework Removable partial denture
EXPERIMENTALpolymer-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.
cobalt chromium framework Removable partial denture
ACTIVE COMPARATORit's the gold standard framework which has many benefits such as they are used in thin sections and are less bulky,provide high strength and stiffness,and some disadvantages include hypersensitivity,metal display and oral galvanism,
Interventions
it is a polyetheretherketone polymer frame combined with acrylic resin denture teeth and a conventional acrylic resin denture base made by injecting technique and have several advantages regarding strength and esthetics
standard framework device
