What should you do with small projections of impression material when relining?

When relining, addressing small projections of impression material is crucial to ensure an accurate fit and optimal function of the new prosthesis. Trimming the projections flush with the ridge promotes a smoother surface and helps in providing a more precise adaptation to the underlying tissues. An uneven or overly thick layer of material can lead to discomfort for the patient and hinder the proper seating of the prosthesis, which can ultimately affect its longevity and effectiveness.

Managing the projections properly helps in achieving even distribution of pressure during use, which is important for the health of the supporting structures. This practice can contribute to a more accurate impression and facilitate better retention and stability of the final dental appliance.

Leaving the projections as they are could lead to fit issues, while completely removing them might disrupt the intended contours necessary for a proper fit. Filling them with wax is not a conventional practice and could lead to complications as wax may not provide the necessary rigidity or fit required in the relining process. Therefore, trimming the projections to be flush with the ridge is the best approach to ensure a well-fitting and functional restoration.
