患者：钛被认为是一种非过敏性材料。然而，一些研究报告了含钛材料引起金属过敏的病例。我们描述了一位 69 岁的男性，从未在他的牙种植体周围观察到明显的病理结果。他在骨科手术后表现出过敏症状（湿疹）。一年后，他接受的骨科手术中使用的钛螺钉被取出，但湿疹仍然存在。移除牙种植体后，湿疹完全消失。讨论：钛不仅用于整形外科和/或牙种植体等医疗应用，还用于油漆、白色颜料、光催化剂和各种日常用品。钛的大部分用途是以二氧化钛的形式。含钛产品的快速扩张增加了人群对钛的经皮和粘膜接触。结论：一般来说，钛材料的过敏风险小于其他金属材料。然而，我们建议应询问植入前患者对金属过敏反应的病史，并建议对经历过此类反应的患者进行斑贴测试。 (C) 2016 年日本修复学会。由爱思唯尔有限公司出版
Patients: Titanium has been considered to be a non-allergenic material. However, several studies have reported cases of metal allergy caused by titanium -containing materials. We describe a 69-year-old male for whom significant pathologic findings around dental implants had never been observed. He exhibited allergic symptoms (eczema) after orthopedic surgery. The titanium screws used in the orthopedic surgery that he underwent were removed 1 year later, but the eczema remained. After removal of dental implants, the eczema disappeared completely.Discussion: Titanium is used not only for medical applications such as plastic surgery and/or dental implants, but also for paints, white pigments, photocatalysts, and various types of everyday goods. Most of the usage of titanium is in the form of titanium dioxide. This rapid expansion of titanium -containing products has increased percutaneous and permucosal exposure of titanium to the population.Conclusions: In general, allergic risk of titanium material is smaller than that of other metal materials. However, we suggest that pre-implant patients should be asked about a history of hypersensitivity reactions to metals, and patch testing should be recommended to patients who have experienced such reactions.
