Why should the use of nickel chromium in base plates be carefully considered?

The appropriate consideration of nickel-chromium usage in base plates stems primarily from the fact that a substantial portion of the female population has a known allergy to nickel. Nickel allergies can cause localized dermatitis or more systemic reactions in sensitive individuals, which highlights the importance of selecting materials for dental applications that minimize the risk of allergic reactions.

In contrast, the options regarding allergies to chromium, whether in females or males, are less commonly recognized in terms of prevalence and do not represent the same level of concern as nickel allergies. Thus, when designing and fabricating dental appliances, prioritizing patient comfort and safety by reducing exposure to materials that may trigger allergic responses, such as nickel, should be a critical consideration.
