A denture that has been worn satisfactorily
for a period of time may become ill-fitting as
alveolar resorption proceeds. The patient isable to continue wear the denture since
neuro-mascular control is gradually learnt.
Elderly patients may never learn to control anew denture, if the contours of the later,
particularly the shape of its polished
surfaces, differ greatly from those of the old
appliance.

Summary of the Indications Replication of the dentures for a spare set.
Replacement of the dentures with provision of: New impression surface, and /or
New occlusal surface, and/or
Slight modification to the VD.
Replacement of dentures whose base material hasdeteriorated.
Production of temporary dentures that can be progressivelymodified if the patients capacity to adapt is in doubt. (slightincrease to the VD or if the cause of the complaint is not
clear/denture collectors). Once a satisfactory appliance hasbeen achieved, it can be copied to produce a definitivedenture

Clinic 1
History & assessment
Assess the old dentures
and decide those features
to be copied and those to
be modified.
Technique Correct any under
extensions by addition of
tracing compound.
The occlusal & polished
surfaces are invested in theselected mould material.
The set material is trimmed
in straight line with the
borders of the denture.

The exposed impression
surface of the denture is
covered by another mix of
the mould material beforethe lid of the container,
filled with more mix, is
seated.
Once set, the container isopened , any tracing
compound is removed,
the denture is cleaned
and returned to thepatient.

Lab 1
Sprue holes, approximately the
diameter of a pencil, are cut inthe alginate from the mostdistal surface to the exterior.
Modeling wax is melted intothe impression of the teeth tothe gingival margin.
After re assembling, self-cureacrylic is poured down onesprue hole to allow airescapement from the other.Once polymerized, thewax/acrylic template isremoved , trimmed andsmoothed.

Clin ic 2:
Impression should be taken as described for
relining techniques. Silicone impression material
is preferred since the template have to be re
inserted in the mouth.After the impression is made, wax is added or
removed to the occlusal surface as needed.
The desired occlusal relation is registered.
The shade and mould of the teeth are noted.

Lab 2
Casts are poured from
the impression surface
and mounted on the
articulator using the
registration provided.
Wax teeth are removed
one or two at a time and
replaced with acrylic
teeth. The templates arethen prepared for trial
insertion (Try-in stage)

Clinic 3
The modified templates are tried in the mouth and
their border extensions, occlusion, jaw relationship,
and aesthetics are noted. Post dame is determined
and carved on the upper master cast.
Lab 3
The templates are flasked and the self cure acrylicbase is removed before the moulds are packed with
the conventional denture base acrylic. The
polymerized dentures are prepared for insertion .
Clinic 4 The dentures are inserted and checked as usual.
