患者の愁訴により歯科インプラントを撤去した１症例

抄録

We encountered a patient who developed multiple symptoms after insertion of a titanium implant at the site of the first molar of the right mandible at another hospital. Eventually, the implant was removed. The patient was a 57-year-old woman who received a titanium dental implant and then was diagnosed as having titanium allergy at a local clinic. She received antiallergy therapy with steroids, but it did not achieve symptomatic relief, so she was referred to our department. To assess the presence of titanium allergy, the patient underwent a patch test for titanium at the Dermatology Department of our hospital. The result was judged to be false-positive for allergy to titanium. Although the dermatologists concluded that she was not allergic to titanium considering the properties of the implant, the patient still strongly wished to have the implant removed. Therefore, we removed the implant on March 26, 2004, although there were no problematic clinical findings. As a result, her symptoms were markedly alleviated and no longer interfered with daily activities.
