Abstract

Purpose: The current study examined the retention and wear resistance of stud-type attachments made of high-performance polyetheretherketone (PEEK) or polyetherketoneketone (PEKK) from the polyaryletherketones (PAEKs) family. Methods: The study sample included 10 PEEK or PEKK attachments that were mounted onto their male parts, designed on the upper aspect of the attachment, with a load of 30 N. Tensile stress was applied using an Instron machine to separate the male and female parts, and the maximum tensile stress to be applied was determined based on the retention force observed. The wear resistances of PEEK and PEKK were evaluated by measuring the inner diameter of the inserted female part 10 times. Results: The maximum tensile stresses of PEEK and PEKK were 56.26±0.58 and 69.12±0.92 N, respectively, with the maximum stress required to remove the PEKK specimens from the abutment being 12.86 N higher than that required to remove the PEEK specimens. Furthermore, PEKK exhibited higher wear resistance than PEEK. Conclusion: This study evaluated custom-made removable implant-retained attachment components for overdentures, wherein the female parts were made of PEEK or PEKK. The retention stress and wear resistance were evaluated based on the type of attachment material, and the results showed that both types of attachment inserts demonstrated clinically acceptable results in terms of retention.
