AIM: The aim of this article is to describe the use of a titanium TSME appliance for patients with allergy to resin and nickel. We aim to highlight the optimal way to avoid problems such as stomatitis and peri-labial dermatitis, which generally appear in patients who use traditional orthodontic appliances made in acrylic resin and steel.
METHODS: The construction of a titanium appliance is described and a case treated with it is reported.
CONCLUSION: The non-allergic properties of titanium allow to propose it as an alternative in patients with a long-term history of allergic reactions to nichel.
