Question 153 · LDEK · Acrylic partial dentures
A patient lost a tooth on which the clasp of a mucosa-supported removable partial denture was placed. In order to allow further use of the denture, the additional artificial tooth and a clasp on the tooth neighboring the edentulous space must be added. Indicate the correct order of doctor’s procedures:
1) impression of the dental arch, without the denture;
2) bite registration of the region of the missing tooth, taken with the denture;
3) alginate impression of the dental arch, with the denture;
4) medium viscosity (body) silicone impression of the dental arch, with the denture;
5) impression of the opposing teeth;
6) if possible, tooth shade matching;
7) transferring the information about the clasp design and location to the dental laboratory;
8) transferring the impressions to the dental laboratory.
