First relining of
existing dentures
®
with Molloplast B
For relining of an existing denture the dentist takes
an impression with the existing denture, using a
medium or light bodied impression material (Fig. 8).
Plaster cast
A master cast of dental stone class III is poured.
Let the master cast set and invest it into a flask
with counter. For easier removal of the denture
from the plaster counter it is recommended to coat
the teeth and also a part of the denture surface
with silicone (FLEXISTONE ® or FLEXISTONE
prior to making the flask counter. Allow plaster to
set completely, open the flask and remove the
impression material from the denture.
Denture base
Reduce acrylic material for approx. 1–3 mm by
means of a coarse grinding stone.
Important:
Provide sufficient retentions to ensure optimum
bonding with Molloplast ® B. For a smooth surface
between acrylic and Molloplast ® B we recommend
to cut grooves evenly into the functional borders
by means of a wheel or fissure bur. Afterwards

denture base. Let Primo air-dry for 60–90 min.
prior to applying Molloplast ® B (Fig. 9).
Insulation
Insulate master cast with an alginate-based insula-
ting liquid.
Packing of Molloplast ® B

la from the jar and apply it evenly onto the denture

place it under the press. The flask must be luke-
warm.
Pressing
Press for approx. 4 min., open the flask and remo-
ve PE-foil and Molloplast ® B excess material.
Control and if necessary apply more Molloplast

press for approx. 15 min. at 100. Place flask in the
clamp and tighten.

100 °C/212 °F.
