The integrity of dental implant surfaces might be compromised during surgical insertion. Wear and topographical modifications can occur during implant insertion, which can potentially have clinical implications. Accordingly, the analysis and prediction of the wear behaviour of dental implant surfaces is fundamental. Surface mean curvature is a key topographical parameter in contact mechanics, related to wear and plastic deformation; however, there is not a consensus on its characterization. In this paper, a critical analysis of the feature parameter S pc from ISO 25178-2 is carried out, which addresses its limited ability to characterize dental implant surfaces. A novel alternative parameter (named ‘relative mean peak curvature’ Δ S dq ) is presented and evaluated in representative dental implant treatments. The obtained results suggest a positive correlation between the surface peak curvature and its tribological signature in biomedical implant...

开发一种新方法来表征平均表面峰曲率，以此作为牙科植入物表面的摩擦学性能的标志

在手术插入过程中，牙齿植入物表面的完整性可能会受到损害。植入物插入过程中可能会发生磨损和形貌变化，这可能具有临床意义。因此，对牙齿植入物表面的磨损行为的分析和预测是至关重要的。表面平均曲率是接触力学中与磨损和塑性变形有关的关键形貌参数；然而，关于其表征尚无共识。在本文中，对ISO 25178-2中的特征参数S pc进行了严格的分析，解决了其表征牙齿植入物表面的能力有限。介绍了一种新颖的替代参数（称为“相对平均峰值曲率”ΔS dq），并在代表性的种植牙治疗中对其进行了评估。
