Comparison Between Injection Molded PEEK Framework and Cobalt Chromium Framework Removable Partial Dentures Regarding Biting Force

Not Applicable

• Conditions: Mandibular Prosthesis User
• Interventions: Device: Cobalt- chromium framework partial dentures; Device: PEEK framework partial dentures

• Registration Number: NCT03777423
• Lead Sponsor: Cairo University

Brief Summary

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 .

Arm && Interventions

Group	Intervention	Description
Cobalt-chromium framework partial dentures	Cobalt- chromium framework partial dentures	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.
PEEK framework partial dentures	PEEK framework partial dentures	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.

Primary Outcome Measures

Name	Time	Method
Biting force	Change in baseline biting force from time of insertion, insertion after 1 month and after 3 months	Biting force of the patient wearing the removable partial denture measured by I-load sensor device.
