Patients who already have an existing set of dentures that have worn or are no longer functioning properly due to fit or wear can consider a conventional denture.   Through a series of impressions, steps and measurements, the denture fabrication process takes 4-5 visits.   Sometimes a new upper can be made to an existing lower or a new lower to an existing upper denture.  A reline of an existing denture may also improve the fit and function of an existing denture. 

With an immediate denture, the denture is made before all of the teeth are extracted and is inserted as soon as the remaining teeth are removed.  The fabrication process takes 3-4 visits.   With immediate dentures, the denture wearer does not have to be without teeth during the healing period.  Please keep in mind however, that healing changes may cause changes in the gums and jaw that may result in more alterations to the denture to achieve adequate fit.
