Objectives: The objective of this study was to compare ZrO 2 , polyether ether ketone (PEEK), and ZrO 2 -PEEK telescopic attachments in terms of retention of overdenture. Methodology: Forty-five acrylic resin models of the lower arch were divided into 3 groups of 15 each. In Group I, primary and secondary crowns were constructed from all zirconia (ZrO 2 ), whereas all PEEK was used for Group II and Group III was made up of ZrO 2 PEEK. Results: The mean retention value in Group I was 14.12 ± 3.4 N, in Group II was 15.86 ± 5.1, and in Group III was 22.40 ± 10.3 N. The mean final initial retention value in Group I was 14.50 ± 6.1 N, in Group II was 14.97 ± 8.2, and in Group III was 17.21 ± 9.3 N. A significant difference was observed in intergroup comparison ( P < 0.05). Conclusion: Zirconia resulted in maximum retention as compared to other telescopic crown materials.

“…In addition, inflammatory infiltrate, vascular endothelial growth factor expression, and microvessel density were reported to be lower around the zirconia restorations than around the titanium ones [ 30 ]. Zirconia can affect the expression levels of some genes in such a way that zirconia can be known as a self-regulatory material that can affect turnover of the extracellular matrix [ 31 ]. In addition, Rinke et al showed that endodontic failures as a biological complication result in a reduced survival rate of approximately 74% in zirconia crowns after the 7-year follow-up study [ 32 ].…”

Zirconia has been used for rehabilitation of edentulous spaces approximately for a decade, and there have been several reports regarding the clinical performance and retention of zirconia crowns. Outstanding mechanical properties, biocompatibility, and excellent aesthetics make zirconia-based crowns as a popular crown among the current all-ceramic crowns in restorative dentistry. However, restoration with a zirconia crown is a challenging treatment. The goal of this study was to assess the current literature to summarize the studies reporting the effective risk factors on retention of zirconia crowns to provide clinicians with a useful point of view in the decision-making process for use of these restorations. Literature based-search was performed to find related articles until August 2020 using EMBASE, Google Scholar, and MEDLINE. Search terms used were “zirconia restorations properties,” “zirconia crowns clinical performance,” “zirconia crown survival,” “biological complications,” and “zirconia crown retention.” Results were limited to papers available in English. The references of all related literature were also searched for further citations. Overall, although clinical long-term and follow-up studies are a vital requirement to conclude that zirconia has great reliability, it seems that zirconia crown restorations are both well tolerated and sufficiently resistant.

The objective of this study is to compare retention capacity of mandibular implant-supported overdenture with all zirconia, zirconia–PEEK, and all PEEK telescopic attachments. Sixty acrylic resin models of mandible were used. Telescopic attachment system was made up of all zirconia, all PEEK, and zirconia–PEEK. Evaluation of retention force was done using universal testing machine. Obtained data were statistically evaluated. Highest initial force value was obtained with zirconia–PEEK group. All PEEK and zirconia–PEEK groups showed significantly decreased final retention values in comparison to their initial values. Zirconia can be regarded as the material of choice for telescopic crown, whereas polyetheretherketone and zirconia–PEEK telescopic crowns showed retention loss over a period of time.
