This review of literature paper was done in order to conduct a review of the literature and an assessment of the effects of titanium implant corrosion on peri-implant health and success in the oral environment. This paper evaluates and critically reviews the findings of the multiple in-depth in vivo and in vitro studies that are related to corrosion aspects of the titanium and its alloys. A literature survey was conducted by electronic search in Medline and studies that were published between 1940 and August 2018 were selected. The search terms used were types of corrosion, corrosion of titanium implants, titanium corrosion, metal ion release from the titanium implants, fretting and pitting corrosion, implant corrosion, peri implantitis, and corrosion. Both in vivo and in vitro studies were also included in the review. The search and selection resulted in 64 articles. These articles were divided on the basis of their context to different kinds of corrosion related to titanium dental implants. It is evident that metal ions are released from titanium and titanium alloy dental implants as a result of corrosion. Corrosion of implants is multifactorial, including electrical, chemical, and mechanical factors, which have an effect on the peri-implant tissues and microbiota. The literature surveyed showed that corrosion related to titanium and its alloys has an effect on the health of peri-implant soft and hard tissue and the long term survival of metal dental implants. It can be concluded that presence of the long-term corrosion reaction along with continuous corrosion leads to the release of ions into the peri-implant tissue but also to a disintegration of the implant that contribute to material fatigue and even fracture of the abutments and implant body or both. This combined impact of the corrosion, bacterial activity, chemical reactions, and functional stresses are to be looked at as important factors of implant failure. The findings can be used to explore the possible strategies of research to investigate the biological impact of implant materials.
撰写这篇文献综述论文的目的是对文献进行回顾,并评估钛植入物腐蚀对口腔环境中种植体周围健康及种植成功的影响。本文评估并批判性地审视了多项与钛及其合金腐蚀方面相关的深入体内和体外研究结果。通过在Medline中进行电子检索开展了文献调查,并选取了1940年至2018年8月期间发表的研究。使用的检索词包括腐蚀类型、钛植入物的腐蚀、钛腐蚀、钛植入物释放的金属离子、微动和点蚀腐蚀、植入物腐蚀、种植体周围炎以及腐蚀。体内和体外研究均纳入了该综述。检索和筛选得到64篇文章。这些文章根据其内容被分为与钛牙种植体相关的不同类型腐蚀。显然,由于腐蚀,金属离子会从钛和钛合金牙种植体中释放出来。植入物的腐蚀是多因素的,包括电、化学和机械因素,这些因素会对种植体周围组织和微生物群产生影响。所调查的文献表明,与钛及其合金相关的腐蚀会对种植体周围软硬组织的健康以及金属牙种植体的长期存活产生影响。可以得出结论,长期腐蚀反应以及持续腐蚀的存在不仅会导致离子释放到种植体周围组织中,还会导致植入物解体,进而导致材料疲劳,甚至基台和植入体主体或两者发生断裂。腐蚀、细菌活性、化学反应和功能应力的这种综合影响应被视为植入物失败的重要因素。这些研究结果可用于探索研究植入材料生物学影响的可能研究策略。
