Abstract

Purpose: To evaluate the efficacy of different surface treatments on the bond strength of polyetherketoneketone (PEKK) to ceramic materials.

Materials and methods: PEKK test specimens were separated into four groups according to surface treatments (group S: sandblasting; group A: acid etching; group SA: sandblasting + acid etching; group C: control). Surface roughness values of PEKK specimens were measured before and after surface treatment. After the prepared PEKK specimens were bonded to lithium-disilicate glass-ceramic specimens with resin cement, they were kept in distilled water at 37°C for 24 h. Half of the specimens in each surface treatment group were thermocycled. All test specimens underwent shear bond strength testing. Failure modes were assessed using light microscopy and SEM.

Results: Statistical analysis demonstrated that surface treatments created significant roughness on the PEKK surfaces (p = 0.005). While group S showed the highest roughness values, group A showed the lowest. Of the thermocycled test groups, the sandblasting + acid etching group obtained the highest shear bond strengths. Among the non-thermocycled test groups, the sandblasting surface treatment group achieved the highest shear bond strengths.

Conclusions: The application of surface treatments to enhance the bond strength of PEKK to ceramics has proven to be effective.

评估聚醚酮酮与牙科陶瓷的粘结强度。

目的：评估不同表面处理方法对聚醚醚酮酮（PEKK）与陶瓷材料粘接强度的影响：根据表面处理方法将 PEKK 试样分为四组（S 组：喷砂；A 组：酸蚀；SA 组：喷砂 + 酸蚀；C 组：对照）。测量表面处理前后 PEKK 试样的表面粗糙度值。用树脂水泥将制备好的 PEKK 试样粘接到二硅酸锂玻璃陶瓷试样上后，在 37°C 的蒸馏水中保存 24 小时。所有试样都进行了剪切粘接强度测试。使用光学显微镜和扫描电镜对失效模式进行评估：统计分析表明，表面处理会使 PEKK 表面产生明显的粗糙度（p = 0.005）。S 组的粗糙度值最高，而 A 组的粗糙度值最低。在热循环测试组中，喷砂+酸蚀组的剪切粘接强度最高。在非热循环试验组中，喷砂表面处理组的剪切粘接强度最高：事实证明，采用表面处理方法提高 PEKK 与陶瓷的粘接强度是有效的。

期刊介绍： New materials and applications for adhesion are profoundly changing the way dentistry is delivered. Bonding techniques, which have long been restricted to the tooth hard tissues, enamel, and dentin, have obvious applications in operative and preventive dentistry, as well as in esthetic and pediatric dentistry, prosthodontics, and orthodontics. The current development of adhesive techniques for soft tissues and slow-releasing agents will expand applications to include periodontics and oral surgery. Scientifically sound, peer-reviewed articles explore the latest innovations in these emerging fields.
