Problem with “S” sound not pronounced. Relieve anterior palatal denture base. 2. Air escaping at lateral borders of tongue because of lack of denture base material restoring tissue. “S” sounds as slushy “sh” or a lisping “th”. Build up lingual tissue roll with wax until problem is corrected. Replace wax with resin.

60 PROTOCOL FOR RELINING COMPLETE DENTURES 1) Examination of patient and existing prostheses. 2) Decide if a reline versus a remake is indicated. Indications for a reline: 1) Minimal to moderate loss of retention and/or stability 2) The vertical dimension of occlusion is satisfactory. 3) The esthetics are satisfactory. 4) The prosthetic teeth are not severely worn. 5) The borders are not grossly over or under-extended 6) The occlusion is satisfactory. If any of these indications are not met, the denture should be remade. * (It is the policy of the Department of Prosthodontics that students should only reline dentures made at the College of Dentistry) 3) Proceed with reline technique. Clinical Procedures for Functional Reline Technique: First Appointment: 1) Make only one reline impression at a time. Treat the less stable denture first. 2) Remove existing undercuts in denture. 3) Reduce any overextended borders and slightly relive tissue surface. Place relief hole(s) if indicated. (under extended borders will require border molding: the standard technique is preferable in this situation) 4) Place tissue conditioner in denture and allow it to thicken for several minutes. 5) Place denture in patient’s mouth and verify proper orientation. Have the patient close lightly into maximum intercuspation with the mandible in centric relation at the appropriate VDO. 6) Remove denture after ten minutes and trim excess material with a sharp lab knife. Replace denture and proceed with opposing denture reline impression if one feels it is appropriate. Otherwise reline opposing denture at separate appointment. 7) Either have patient wait one hour, or dismiss patient with instructions to wear dentures until they return. The patient should return within 48 hours. (Note: if patient has a bruxing habit, do not have them leave the dentures in overnight.)
61 Inspection of Reline Impression: (at least one hour later, but not over 48 hours) 1) Inspect tissue conditioner in the denture. If there are areas of acrylic showing through the material, relieve them and place a thin layer of new tissue conditioner in the denture. Replace denture in patient's mouth and re-evaluate after twenty minutes. Once the material appears uniform and accurate, box and pour immediately in Type III stone and send denture(s) to the laboratory for placement of posterior palatal seal and processing. (It is important to instruct the laboratory on the proper posterior palatal seal design for each individual patient.) Delivery Appointment: 1) Inspect processed dentures.
