研究组 & 干预措施
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.
干预措施: 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,
干预措施: cobalt chromium framework RPD (Device)
结局指标
主要结局
Retention
时间窗: 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
