Abstract

Purpose: Polyetheretherketone (PEEK) is a new polymeric material that has received significant attention in dentistry because of its mechanical properties, biocompatibility, and aesthetics. However, the bonding performance of PEEK to other materials is not preferable. This study aimed to analyze the variations in the surface characteristics of PEEK under the chemical action of primers containing different functional monomers or polymers and to evaluate the bonding performance of PEEK and dental cement.

Methods: Disk-shaped PEEK samples were prepared by dental milling, blasting with alumina oxide, and covering with primers containing functional monomers or polymers. The surface characteristics of the samples were analyzed by microscopy and spectroscopy. The shear bond strength (SBS) between PEEK and dental cement, with and without thermocycling, was tested using a universal testing machine. Finally, the data were statistically analyzed and compared.

Results: Functional monomers or polymers were successfully bonded to the surface of PEEK. This treatment significantly improved its hydrophilicity and surface free energy (P < 0.05). The primer containing pentaerythritol triacrylate had the highest SBS without thermocycling (13.89 MPa). Meanwhile, the primers containing urethane dimethacrylate (UDMA) and methyl methacrylate (MMA) (abbreviated as the HC group) showed the highest SBS and lowest reduction (25.51%) after thermocycling. Notably, all the testing groups achieved the ISO10477 standard of 5 MPa. After thermocycling, adhesive failure accounted for the largest proportion of failures in all the groups except the HC group.

Conclusions: The chemical priming treatment can significantly improve the SBS of PEEK and dental cement. Moreover, a primer containing both UDMA and MMA can provide improved bonding for PEEK materials.

各种功能性单体反应对聚醚醚酮表面特性和粘合性能的影响。

目的：聚醚醚酮（PEEK）是一种新型聚合物材料，因其机械性能、生物相容性和美观性而受到牙科界的广泛关注。然而，PEEK 与其他材料的粘接性能并不理想。本研究旨在分析 PEEK 在含有不同功能单体或聚合物的底漆化学作用下的表面特性变化，并评估 PEEK 与牙科粘接剂的粘接性能：方法：通过牙科研磨制备盘状 PEEK 样品，用氧化铝喷砂，然后覆盖含有功能性单体或聚合物的底漆。用显微镜和光谱分析了样品的表面特征。使用万能试验机测试了 PEEK 和牙科粘接剂之间的剪切粘接强度（SBS），包括热循环和非热循环。最后，对数据进行了统计分析和比较：结果：功能性单体或聚合物成功地粘合到了 PEEK 表面。这种处理方法大大提高了其亲水性和表面自由能（P < 0.05）。含有季戊四醇三丙烯酸酯的处理剂在不进行热循环的情况下具有最高的 SBS（13.89 兆帕）。同时，含有聚氨酯二甲基丙烯酸酯（UDMA）和甲基丙烯酸甲酯（MMA）的底涂（简称为 HC 组）在热循环后显示出最高的 SBS 和最低的缩减率（25.51%）。值得注意的是，所有测试组都达到了 5 兆帕的 ISO10477 标准。热循环后，除 HC 组外，其他各组的粘合剂失效比例最大：结论：化学打底处理可明显改善 PEEK 和牙科粘接剂的 SBS。此外，含有 UDMA 和 MMA 的打底剂还能改善 PEEK 材料的粘接效果。

期刊介绍： Journal of Prosthodontic Research is published 4 times annually, in January, April, July, and October, under supervision by the Editorial Board of Japan Prosthodontic Society, which selects all materials submitted for publication. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. The Journal will cover all diagnostic and clinical management aspects necessary to reestablish subjective and objective harmonious oral aesthetics and function. The most-targeted topics: 1) Clinical Epidemiology and Prosthodontics 2) Fixed/Removable Prosthodontics 3) Oral Implantology 4) Prosthodontics-Related Biosciences (Regenerative Medicine, Bone Biology, Mechanobiology, Microbiology/Immunology) 5) Oral Physiology and Biomechanics (Masticating and Swallowing Function, Parafunction, e.g., bruxism) 6) Orofacial Pain and Temporomandibular Disorders (TMDs) 7) Adhesive Dentistry / Dental Materials / Aesthetic Dentistry 8) Maxillofacial Prosthodontics and Dysphagia Rehabilitation 9) Digital Dentistry Prosthodontic treatment may become necessary as a result of developmental or acquired disturbances in the orofacial region, of orofacial trauma, or of a variety of dental and oral diseases and orofacial pain conditions. Reviews, Original articles, technical procedure and case reports can be submitted. Letters to the Editor commenting on papers or any aspect of Journal of Prosthodontic Research are welcomed.
