Wear Assessment of Novel PEEK Telescopic Attachment for Overdenture

Not Applicable

Completed

• Conditions: Stress Disorder; Attachment Disorder
• Interventions: Procedure: implant overdenture

• Registration Number: NCT06434142
• Lead Sponsor: Hamada Zaki Mahross Atia

Brief Summary

To assess the wear of Zirconia-PEEK versus cobalt-chromium-PEEK telescopic attachments for implant retained complete mandibular overdenture. The wear of Zirconia-PEEK telescopic attachments can affect the retention of implant retained complete mandibular overdenture.

Detailed Description

Twelve completely edentulous patients were randomly chosen for implant retained telescopic overdentures construction and divided into two groups, where group I was a patient with zirconia copy, and group II was with cobalt chromium CoCr copy. The PEEK was constructed for both groups as a secondary coping telescopic attachment for the denture. The wear measurements of PEEK were performed optically by using a USB digital microscope with a built-in camera connected to a compatible personal computer at different intervals of baseline, 3, 6, and 9 months. The data was statistically analyzed and compared using student t-test, ANOVA, and Post Hoc Test.

Arm && Interventions

Group	Intervention	Description
patient with zirconia copy	implant overdenture	Group I (study group) was the group of patients with zirconia as a primary copings that attach to the abutment and PEEK as a secondary coping telescopic attachment that attaches to the fitting surface of the denture.
patients with cobalt chromium (CoCr) as primary copings	implant overdenture	Group II (control group) was the group of patients with cobalt chromium (CoCr) as primary copings attached to the abutment and PEEK as a secondary coping's telescopic attachment attached to the fitting surface of the denture.

Primary Outcome Measures

Name	Time	Method
