Abstract

BACKGROUND

Considerations about implant surface wear and metal particles released during implant placement have been reported. However, little is known about implant surface macro- and microstructural components, which can influence these events. The aim of this research was to investigate accurately the surface morphology and chemical composition of commercially available dental implants, by means of multivariate and multidimensional statistical analysis, in order to predict their effect on wear onset and particle release during implant placement.

METHODS

The implant surface characterization (roughness, texture) was carried out through Confocal Microscopy and SEM-EDS analysis; the quantitative surface quality variables (amplitude and hybrid roughness parameters) were statistically analyzed through post hoc Bonferroni's test for pair comparisons.

RESULTS

The parameters used by discriminant analysis evidenced several differences in terms of implant surface roughness between the examined fixtures. In relation to the observed surface quality, some of the investigated implants showed the presence of residuals due to the industrial surface treatments.

CONCLUSIONS

Many structural components of the dental implant surface can influence the wear onset and particles released during the implant placement.

摘要

背景

已有报道提及种植体植入过程中种植体表面磨损及释放金属颗粒的相关问题。然而，对于可能影响这些情况的种植体表面宏观和微观结构组成，人们却知之甚少。本研究的目的是通过多变量和多维统计分析，准确探究市售牙科种植体的表面形态和化学成分，以预测其在种植体植入过程中对磨损起始和颗粒释放的影响。

方法

通过共聚焦显微镜和扫描电子显微镜 - 能谱分析（SEM - EDS）对种植体表面特征（粗糙度、纹理）进行表征；通过事后邦费罗尼检验进行成对比较，对定量表面质量变量（幅度和混合粗糙度参数）进行统计分析。

结果

判别分析所使用的参数表明，在所检查的种植体之间，种植体表面粗糙度存在若干差异。就观察到的表面质量而言，一些被研究的种植体显示出因工业表面处理而存在的残留物。

结论

牙科种植体表面的许多结构组成会影响种植体植入过程中的磨损起始和颗粒释放。
