Wear Assessment of Novel PEEK Telescopic Attachment for Overdenture

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.

About this study

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.
