1. The document describes preparing dentures for delivery, including fabricating a facebow transfer jig, finishing and polishing the dentures, and making clinical remount casts. 2. The dentures are removed from the master casts using plaster knives or air hammers and polished using pumice, rag wheels, and felt cones to smooth the surfaces. 3. Remount casts are made by blocking out undercuts on the denture and embedding it in plaster, then the casts are used to mount the clinical remount records on the articulator.

4. Preparing Dentures for Delivery
 Fabrication of face bow remount jig
 Removing Processed Dentures from Master
Casts
 Finishing Polishing Dentures
 Fabrication of clinical remount casts
 Mount the maxillary remount cast on the
articulator preserving the facebow transfer
record

5. Fabricate Facebow Remount Jig*
 Attach processed upper denture with its mounting to
the upper member of the articulator and attach a
mounting ring to the lower member of the articulator.
 Fabricate facebow transfer jig as shown. Note that
only the occlusal and incisal surfaces of the denture
teeth engage the remount jig. Confine the plaster
with a paper cup from which the bottom has been
removed.
 Smooth the surfaces of the remount jig because it
will be used in the presence of the patient.
*The pupose of this jig is to preserve the face bow mounting record.

6. Removing Dentures from Casts and Polishing
Instruments and Materials
 Plaster knife
 Acrylic Burs
 Pumice
 Rag polishing wheels
 Felt cones
 Brush wheels
 Kingsly scraper

7. Removing Dentures from the Master Casts
 Make cuts into the base
of each cast almost to
the resin.
 Insert the plaster knife
into the cuts and
carefully separate the
sections of stone.
 On the right a vibrating
air hammer is being
used to separate the
denture from the cast.
 Remove all stone from
dentures. The Kingsley
scraper is particularly
useful in removing
tenacious elements.

8. Finishing and Polishing
 Finish borders with an acrylic bur. Remove excess
resin beyond the land. Be careful to preserve the
border width and contour.
 Remove all plaster or stone.
 Smooth the denture bases to the proper contour
with your acrylic burrs.
 Bubbles and other irregularities around the denture
teeth can be removed with chisels or scrapers.

9. Finishing and Polishing
• Remove small particles of stone from the proximal areas
with a brush wheel.
• The palatal portion should 1-2 mm thick.

10. Finishing and Polishing
 Check the bearing surfaces of the
dentures for bubbles and sharp

11. Finishing and Polishing
 Use a very wet rag wheel with liberal amounts of wet pumice to polish the
palatal, lingual, labial and buccal areas. The periphery of the denture must
also be carefully polished. Use the edge of the wheel as shown during
polishing to avoid burning the acrylic resin. Do not overpolish and thereby
loose the contours that were developed during festooning.

12. Finishing and Polishing
Polished dentures
Note that the borders are rounded and smooth, and the palate is highly
polished and the proper thickness
Be careful not to overpolish the occlusal
or incisal surfaces of the denture teeth.
Do not over polish

13. Finishing and Polishing
 Reexamine the
tissue side of the
dentures and
carefully remove
any bubbles present
with a Kingsley
scraper or other
sharp instrument.
•Prior to delivery the dentures
must be soaked in water for 72
hours.

14. Fabrication of Remount Casts
Purpose:
Provide casts with which to mount the
clinical remount record

15. Remount Casts
Begin by blocking out the undercuts
associated with the undersurface of the
dentures with moistened pumice.

16. Remount Casts
 Mix a small amount of impression plaster, place it on
the lab bench and imbed the denture into it as shown.

18. You are now ready to perform the
clinical remount procedure
The maxillary
remount cast has
been connected to the
upper member of the
articulator by means
of the facebow
transfer jig. With the
lower remount cast
you are now ready to
perform the clinical
remount procedure.
