Maxillary Fracture Repair
The broken edges are cleaned of debris and other interferences so that the two parts will fit together well
The two halves are held together by means of an old bur, which is luted to the teeth and resin surfaces by means of sticky wax
No wax is placed over the fracture so that the tissue and palatal sides of the fracture can be examined to see that they are in correct apposition
Plaster is vibrated gently onto the palatal side to prevent air bubles and is then set on the balance of the mix to form cast
Repairs using cold-curing resin
Adapte a tinfoil to the basal surface of the denture
Pour plaster inside the denture
When setting time of the plaster was overed, remove the cast from the denture
Cut avay and beveled the resin on both sides of the break
Replace the cast
Paint the acrylic resin monomer on the cut surfaces
Place a cold-curing repair resin in the break
Fill the area to be repaired withe alternate applications of monomer and polymer
Slightly overfill the area to allow for finishing
Curing Under Air Pressure
Pressure can be maintained on the cold-curing resin while it cures by placing the denture in a pressure cooker after the resin has been forced into place
Use a pressure which will condense the repair resin
This curing method can be used when the repair resin is added in small increments of powder (polymer) and liquid (monomer)
Without this pressure, the resin added in this manner is less dense than resin cured under pressure
