About

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.

Full 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.

20 participants in 2 patient groups

patient with zirconia copy

Experimental group

Description:

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.

Treatment:

Procedure: implant overdenture

patients with cobalt chromium (CoCr) as primary copings

Experimental group

Description:

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.

Treatment:

Procedure: implant overdenture
