Question 21 (part 2) · LDEK · Complete dentures
During checking the complete prostheses, the dentist found lack of contacts in the left lateral part (underbite). Occlusion height is correct. Occlusal plane in the upper prosthesis is also correct. In such situation it is advised to:
1) return the prosthetic work to the lab with comments, ask for switching of the teeth and finishing the prostheses;
2) return the prosthetic work to the lab with comments and ask for new occlusal rims;
3) fabricate new lower occlusal rim during the same visit, establish and register the occlusion;
4) remove the teeth from the lower prosthesis in the underbite location during the same visit, fabricate and plasticize occlusal shaft and register the occlusion;
5) register the occlusion during the same visit using wax or silicone register, using mock dentures.
Correct answer is:
2) return the prosthetic work to the lab with comments and ask for new occlusal rims;
3) fabricate new lower occlusal rim during the same visit, establish and register the occlusion;
4) remove the teeth from the lower prosthesis in the underbite location during the same visit, fabricate and plasticize occlusal shaft and register the occlusion;
5) register the occlusion during the same visit using wax or silicone register, using mock dentures.
Correct answer is:
- A. 1,2.
- B. only 3.
- C. only 4.
- D. only 5.
- E. 4,5.
Hint
A one-sided posterior open contact with correct height and plane points to a registration error; correct it at the chair before the teeth are reset.
