Abstract

PURPOSE

This study was conducted to evaluate the effects of plasma treatment of sandblasted and acid-etched (SLA) titanium implants on surface cleansing and osseointegration in a beagle model.

MATERIALS AND METHODS

For morphological analysis and XPS analysis, scanning electron microscope and x-ray photoelectron spectroscopy were used to analyze the surface topography and chemical compositions of implant before and after plasma treatment. For this animal experiment, twelve SLA titanium implants were divided into two groups: a control group (untreated implants) and a plasma group (implants treated with plasma). Each group was randomly located in the mandibular bone of the beagle dog (n = 6). After 8 weeks, the beagle dogs were sacrificed, and volumetric analysis and histometric analysis were performed within the region of interest.

RESULTS

In morphological analysis, plasma treatment did not alter the implant surface topography or cause any physical damage. In XPS analysis, the atomic percentage of carbon at the inspection point before the plasma treatment was 34.09%. After the plasma treatment, it was reduced to 18.74%, indicating a 45% reduction in carbon. In volumetric analysis and histometric analysis, the plasma group exhibited relatively higher mean values for new bone volume (NBV), bone to implant contact (BIC), and inter-thread bone density (ITBD) compared to the control group. However, there was no significant difference between the two groups ( > .05).

CONCLUSION

Within the limits of this study, plasma treatment effectively eliminated hydrocarbons without changing the implant surface.

摘要

目的

本研究旨在评估等离子体处理对喷砂和酸蚀（SLA）钛种植体表面清洁及骨整合的影响，实验采用比格犬模型。

材料与方法

为进行形态学分析和X射线光电子能谱（XPS）分析，使用扫描电子显微镜和X射线光电子能谱仪分析等离子体处理前后种植体的表面形貌和化学成分。在本动物实验中，将12枚SLA钛种植体分为两组：对照组（未处理的种植体）和等离子体组（经等离子体处理的种植体）。每组随机植入比格犬的下颌骨（n = 6）。8周后，处死比格犬，并在感兴趣区域内进行体积分析和组织计量分析。

结果

形态学分析显示，等离子体处理未改变种植体表面形貌，也未造成任何物理损伤。XPS分析表明，等离子体处理前检测点处碳的原子百分比为34.09%。等离子体处理后，该值降至18.74%，表明碳含量降低了45%。体积分析和组织计量分析结果显示，与对照组相比，等离子体组的新骨体积（NBV）、骨与种植体接触面积（BIC）和螺纹间骨密度（ITBD）的平均值相对较高。然而，两组之间无显著差异（P > 0.05）。

结论

在本研究范围内，等离子体处理可有效去除碳氢化合物，且不改变种植体表面。
