About

This study is aiming to evaluate the biting force of polyetheretherketone (PEEK) framework partial dentures compared to that of cobalt-chromium ones in mandibular Kennedy class I edentulous cases hoping that polyetheretherketone (PEEK) framework removable partial dentures can improve the patient masticatory efficiency .

30 participants in 2 patient groups

PEEK framework partial dentures

Experimental group

Description:

High performance ketone polymers introduced lately.These polymer-based frameworks provide better esthetics, higher elasticity, lighter in weight, have low water sorption and solubility, and are easily repaired and reproduced.

Treatment:

Device: PEEK framework partial dentures

Cobalt-chromium framework partial dentures

Active Comparator group

Description:

it is considered the gold standard framework. These frameworks are less bulky with high strength, conduct heat and electricity well, and have good durability. some disadvantages include hypersensitivity, adverse tissue reactions and bad aesthetics.

Treatment:

Device: Cobalt- chromium framework partial dentures
