Abstract

Previous studies have highlighted the need for post-treatment of implants due to surface aging. This study investigated the effect of vacuum plasma (VP) treatment on the osseointegration of sandblasted, large grit, acid-etched (SLA) implant surfaces. The hypothesis was that VP might enhance implant stability, measured by implant stability quotient (ISQ) and histological osseointegration through bone-to-implant contact (BIC) and bone area ratio (BA) in rabbit models. Eighteen implants were either untreated or treated with VP and installed into the femurs of six rabbits, which were sacrificed after four weeks. Histological analyses of BIC and BA, along with micro-CT analysis of bone volume and ISQ, were performed. The VP-treated group showed higher levels of BA, bone volume, and ISQ, but no statistically significant differences were observed between the control and experimental groups. Despite limitations, both groups achieved better osseointegration and regeneration, warranting further studies on plasma treatment effects over varying implantation periods.

体内真空等离子体表面处理后牙科植入物的骨结合。

以往的研究强调，由于表面老化，需要对种植体进行后处理。本研究调查了真空等离子（VP）处理对喷砂、大颗粒、酸蚀（SLA）种植体表面骨结合的影响。假设 VP 可以提高种植体的稳定性（通过种植体稳定性商数（ISQ）来衡量），并通过兔模型中的骨-种植体接触（BIC）和骨面积比（BA）来提高组织学上的骨结合。18 个种植体在未经处理或使用 VP 处理的情况下被植入 6 只兔子的股骨，4 周后兔子被处死。对 BIC 和 BA 进行了组织学分析，并对骨量和 ISQ 进行了显微 CT 分析。VP治疗组显示出更高水平的BA、骨量和ISQ，但对照组和实验组之间没有统计学上的显著差异。尽管存在局限性，但两组都获得了更好的骨结合和再生效果，因此有必要对不同植入期的等离子处理效果进行进一步研究。

期刊介绍： Journal of Functional Biomaterials (JFB, ISSN 2079-4983) is an international and interdisciplinary scientific journal that publishes regular research papers (articles), reviews and short communications about applications of materials for biomedical use. JFB covers subjects from chemistry, pharmacy, biology, physics over to engineering. The journal focuses on the preparation, performance and use of functional biomaterials in biomedical devices and their behaviour in physiological environments. Our aim is to encourage scientists to publish their results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Several topical special issues will be published. Scope: adhesion, adsorption, biocompatibility, biohybrid materials, bio-inert materials, biomaterials, biomedical devices, biomimetic materials, bone repair, cardiovascular devices, ceramics, composite materials, dental implants, dental materials, drug delivery systems, functional biopolymers, glasses, hyper branched polymers, molecularly imprinted polymers (MIPs), nanomedicine, nanoparticles, nanotechnology, natural materials, self-assembly smart materials, stimuli responsive materials, surface modification, tissue devices, tissue engineering, tissue-derived materials, urological devices.
