The laboratory reline is of better quality and tends to last longer than a chairside reline. This process requires the patient to be without his dentures for a short while to allow the laboratory to complete the process. In the predoctoral clinic, the patient is scheduled for a reline impression in the early morning and the denture is returned for insertion in late afternoon. The patient should be advised ahead of the appointment to leave the dentures out for 24 hours prior to the appointment to allow the tissues to reach a state of rest.
