30 participants in 2 patient groups

cobalt-chromium framework partial dentures

Active Comparator group

Description:

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.

Treatment:

Device: cobalt-chromium framework partial dentures

PEEK framework partial dentures

Experimental group

Description:

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.

Treatment:

Device: PEEK framework partial dentures
