Over the past three decades there has been an improvement in biomaterials that has virtually replaced the use of stainless steel with titanium and its alloys. Based on the possibility of causing corrosion, toxicity, hypersensitivity, and stress protection, stainless steel should not be considered as a permanent implant in maxillofacial fixation. However, because of their superior corrosion resistance, noncarcinogenicity, hyposensitivity, nontoxicity, and excellent tissue compatibility, titanium and Ti-6Al-4V may be retained as permanent implants in maxillofacial fixation. The stress protection offered by such devices, and the possible complications associated with their removal, also support this concept. Finally, the costs incurred in removal do not justify the benefits derived.
在过去三十年中，生物材料有了改进，实际上已经用钛及其合金取代了不锈钢的使用。基于可能导致腐蚀、毒性、超敏反应和应力保护的因素，不锈钢不应被视为颌面固定中的永久性植入物。然而，由于钛和Ti-6Al-4V具有优异的耐腐蚀性、无致癌性、低过敏性、无毒性和出色的组织相容性，它们可作为颌面固定中的永久性植入物保留下来。此类装置提供的应力保护以及与其取出相关的可能并发症，也支持这一观点。最后，取出所产生的成本并不足以证明其带来的益处是合理的。
