In a denture patient with maxillary tori, what is the necessary step before fabricating a new denture?

Before fabricating a new denture for a patient with maxillary tori, removing the tori is a necessary step. This is because tori, which are bony growths, can create an improper fit for the denture, causing discomfort, instability, and potential irritation to the oral tissues. By removing the tori, the underlying bone is reshaped, allowing for a better fit of the new denture and enhancing the comfort and functionality for the patient.

In cases where tori are present, merely adjusting the existing denture would not be sufficient since the fundamental issue of the underlying anatomy causing the ill-fitting denture remains unaddressed. Using a soft liner could provide temporary comfort but does not solve the underlying fit issue and may eventually lead to additional complications if the tori remain. Making a duplicate denture does not address the anatomical obstacle caused by the tori, and thus would not be an effective solution prior to creating a properly fitting new denture.
