Question 317 · LDEK · Dental laboratory technology
A denture repair clinic to which a patient brought their broken prosthesis will repair the prosthesis using a cold-curing resin. Choose the appropriate descriptions and arrange them in the correct order to indicate how the prosthesis will be repaired.
1) provisionally glue the two pieces of the prosthesis together (unless already done by a physician);
2) make a gypsum cast of the impression surface of the prosthesis;
3) make a gypsum cast of the polished surface of the prosthesis;
4) widen and grind the edges of the gap between the two pieces of the broken prosthesis;
5) place the prepared pieces on the model;
6) use self-polymerizing resin to replace the missing base plate;
7) use boxing wax to replace the missing base plate;
8) place in a pressure pot;
9) place in a cooking box; 10) processing, polishing.
The correct answer is:
2) make a gypsum cast of the impression surface of the prosthesis;
3) make a gypsum cast of the polished surface of the prosthesis;
4) widen and grind the edges of the gap between the two pieces of the broken prosthesis;
5) place the prepared pieces on the model;

7) use boxing wax to replace the missing base plate;
8) place in a pressure pot;
9) place in a cooking box; 10) processing, polishing.
The correct answer is:
- A. 1,3,4,5,6,8,10.
- B. 1,3,4,5,7,9,10.
- C. 1,2,4,5,6,10.
- D. 1,2,4,5,7,8,10.
- E. 1,2,4,5,6,8,10.
Hint
In a cold-cure repair the cast is poured into the tissue side, no wax or flasking is needed, and curing under pressure reduces porosity.
