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.
本研究的目的是比较全锆、锆-聚醚醚酮和全聚醚醚酮套筒冠附着体在下颌种植覆盖义齿中的固位能力。使用了60个丙烯酸树脂下颌模型。套筒冠附着系统由全锆、全聚醚醚酮和锆-聚醚醚酮制成。使用万能试验机进行固位力评估。对获得的数据进行统计学评估。锆-聚醚醚酮组获得了最高的初始力值。与初始值相比，全聚醚醚酮组和锆-聚醚醚酮组的最终固位值均显著降低。锆可被视为套筒冠的首选材料，而聚醚醚酮和锆-聚醚醚酮套筒冠在一段时间后显示出固位力丧失。
