(2) On the next appointment, the denture is inserted after fit and occlusion
have been verified and adjusted. The patient is instructed in the use and care of the
denture. Other appointments may be given as needed for further adjustments.
b. Impressions. An irreversible hydrocolloid or polysulfide base impression
material is used in making impressions for removable partial dentures. The instruments
and materials used are the same for removable partial dentures as for complete
dentures. See figures 5-10, 5-11, and 5-12.
c. Dental Specialist's Duties. The dental specialist prepares the impression
tray in accordance with the dental officer's instructions, mixes the impression material
according to the manufacturer's directions, and may fill the tray with the mixed
impression material. When the impression has been removed from the patient's mouth,
the dental specialist cleans any impression material from the patient's face and lips. For
care and handling of the impression, see paragraph 5-7b.
d. Jaw Relationship Records. Frequently there are enough remaining teeth to
determine the proper relationship for mounting casts on an articulator. If insufficient
teeth remain for this purpose, baseplates adapted to edentulous areas of the cast and
fitted with properly contoured compound or wax occlusion rims may be used to record
relationships in the mouth. Denture tooth shades and mold desired may be selected at
this appointment. Figure 5-16 depicts instruments and materials used for jaw
relationship records in removable partial denture fabrication.
