Titanium TSME appliance for patients allergic to nickel

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. Materials and methods The construction of a titanium appliance is described and a case treated with it is reported. Results The titanium TSME presented in this paper has excellent biocompatibility due to its ability to form superficial oxides, which prevent oxidation and thus corrosion. 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.
