Denture repairs may be classified as either simple or complex. A simple repair is one requiring but one operation, such as the replacing of a single tooth or the rejoining of two parts of a broken denture.
A complex repair may involve the replacing or the addition of teeth, clasps, or even entire sections of the denture. In either type, the utmost care and precision is required to restore the denture to its original usefulness. It would be impossible to describe every type or repair, but the following techniques may be modified to include the same material of which the denture is made. The repaired denture is as strong as the original one, and the line of cleavage is practically invisible. To prevent the denture from warping during repair, the processing temperature must be kept at 165° F. for 2 ½ hours. Never boil a repair! To do so might cause the appliance to warp or to become distorted.
Repair or Broken dentures:
a) Assemble the pieces of the broken denture, and lute them together with sticky wax. The assemblage may be strengthened with matchsticks or with pieces of a wooden applicator (if part of the denture base is missing, the dental officer will replace it with some impression material and mold it to shape in the patient’s mouth.) Examine the tissue side of the denture to see that the parts are in correct position. Gently vibrate a small amount of stone mix onto the tissue side to prevent the formation of air bubbles, and than invert the denture on to the remainder of the mix to form the base.
