Dentures - Lecture 3 Pouring Master
Cast and Record Base Fabrication
(Beading and Boxing), Wax Rim
What are the laboratory steps for this point in making the denture?
First do beading and boxing impressions then pour the master casts the trim
and index the casts
What is the purpose of beading/boxing and pouring the master cast?
To fabricate a cast that:
- Preserves the peripheral
role
- Provides a protective rim
around the cast defined as
the land area. This land
area must be 4-5 mm wide.
- Produce a dense cast of
vacuum mixed stone of the
proper dimension (10- 15
mm thick) to permit
flasking.
, How thick should the land area of the master cast be for maxilla?
Also what is the depth of the peripheral roll?
How thick should the mandible base be?
Next cards are about the steps for beading and boxing (we did this in
preclinic)
Explain how to bead and box the maxillary impression
Then?
Next?
Explain how to bead and box the mandibular impression?
