When constructing a shellac baseplate, what safety precaution should be observed?

When constructing a shellac baseplate, preventing overheating is a crucial safety precaution to ensure both the integrity of the material and the safety of the individual handling it. Shellac baseplates are typically made from thermoplastic materials that can be molded when heated. If these materials are overheated, they can become too pliable or even degrade, compromising their structural integrity and leading to distortion.

Additionally, overheating can present safety risks, such as burns or the release of potentially harmful fumes. Careful management of the temperature during the preparation process is essential to achieve the desired physical characteristics of the baseplate while ensuring a safe working environment. Following appropriate temperature guidelines helps maintain the efficacy of the shellac and the comfort of the patient when the final product is used in dental applications.
