30 participants in 2 patient groups

peek framework Removable partial denture

Experimental group

Description:

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.

Treatment:

Device: peek framework RPD

cobalt chromium framework Removable partial denture

Active Comparator group

Description:

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,

Treatment:

Device: cobalt chromium framework RPD
