Denture relines are typically performed when there has been a change in the underlying tissues, or significant bone loss.
This change will create a gap beneath the denture, and likely cause undesirable mobility or loss of retention. Change in weight, tooth loss, or sickness can also lead to issues with fit. The bite position, existing teeth and acrylic base(s) must be in good condition and have minimal wear for a reline to be successful. An impression of your oral tissue is taken inside your denture(s) to provide a working model. New acrylic base material is added to your denture to produce a correct fit.
