Arms & Interventions
peek framework Removable partial denture
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.
Intervention: peek framework RPD (Device)
cobalt chromium framework Removable partial denture
it'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,
Intervention: cobalt chromium framework RPD (Device)
Outcomes
Primary Outcomes
Retention
Time Frame: change from baseline retention force after one month and after three months
retention force of RPD during attachment/detachment cycles measured by digital force meter device
Secondary Outcomes
No secondary outcomes reported
