OBJECTIVES
The objective of this study was to compare ZrO, polyether ether ketone (PEEK), and ZrO-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), whereas all PEEK was used for Group II and Group III was made up of ZrO 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 ( < 0.05).
CONCLUSION
Zirconia resulted in maximum retention as compared to other telescopic crown materials.
目的
本研究的目的是比较氧化锆、聚醚醚酮（PEEK）以及氧化锆-PEEK套筒冠附件在覆盖义齿固位方面的表现。
方法
将45个下颌牙弓的丙烯酸树脂模型分为3组，每组15个。在第一组中，初级和次级冠由全氧化锆（ZrO）制成，而第二组全部使用PEEK，第三组由ZrO-PEEK组成。
结果
第一组的平均固位值为14.12±3.4 N，第二组为15.86±5.1 N，第三组为22.40±10.3 N。第一组的平均最终初始固位值为14.50±6.1 N，第二组为14.97±8.2 N，第三组为17.21±9.3 N。组间比较存在显著差异（P<0.05）。
结论
与其他套筒冠材料相比，氧化锆产生的固位力最大。
