The document outlines the steps involved in fabricating a removable partial denture, which includes both clinical and laboratory steps. The clinical steps include diagnosis, treatment planning, impressions, framework try-in, and denture insertion. The laboratory steps involve model preparation, surveying, framework fabrication, waxing, flasking, curing, and finishing. Key steps include diagnostic impressions to create study models, designing the prosthesis framework, final impressions, packing denture base material into the mold, curing, and inserting the final denture.

3. Removable Partial Denture
 A denture is a replacement for missing teeth and
surrounding tissues.
 Complete Denture
 Partial Denture
A removable partial denture usually consists of
replacement teeth (Artificial Teeth) attached
to a pink or gum-colored acrylic base
(Denture Base), which is connected by metal
framework (CLASPS) that holds the denture in
place in the mouth.

15. Final Impression
 These are negative replica of patients hard and soft
tissues of Oral cavity usually taken using alginate
(Impression Material) in a stock/ custom tray.

16. Model Preparation
 After Impression.
 By Cast or Die
materials;
 Plaster of Paris
 Dental Stone

17. Survey
 Used to determine
heights of contour
with a common path
of insertion.
 A dental surveyor is
Used

18. Fabricating Framework
 Casting wax Pattern
 Block undercuts &
relief areas
 Refractory Cast is
invested
 Wax is burnt out and
molten metal is
replaced
 Finishing &

24. Flasking
 The process of investing the cast and a waxed
denture in a flask to make a sectional mould
used to form the acrylic resin denture base.

25. Flasking Procedure
 Separating Media Application.
 Pouring of Plaster.
 Insertion of Model.
 Cover Model with Plaster except on Tooth &
Wax.
 Separating Media Application.
 Upper Part Attachment.
 Fill Upper Part with Plaster Again.
 Cover Upper Tray with Lid & allow it to set.

28. Dewaxing
 Wax
Elimination.
 Boiling Water
for 4 to 6
minutes.
 Excess Wax
can be
washed away
with boiling
water.

After
Dewaxing

29. Application of Seperating Media
 Camel's Hair Brush or Cotton
held in Tweezers.
 Apply everywhere on cast except
Artificial Teeth.
 Allow to cool to room
temperature.
 Materials
 Cold mould seal
 Tin foil
 Starch
 Vaselin
 Cellulose Acetate

30. Packing
 It is act of pressing a denture base material
(Dough Stage) into a mold within flask.
 Rod-like form
 In the upper half of the flask .
25

31. Curing
 Polymerization of Denture Base material.
 Self/ Chemical Curing.
 Heat Curing.
 Heat for 45 min
 After 45 min allow it to cool
26

32. 32
 Deflasking
 Disassembling of Flask to get
Denture.
 Finishing & Polishing
 Grinding
 Polishing with pumice
 Brushes and rag wheels suitable for
polishing
 Polishing compound
 No. 6 or 8 round bur
 Carbide acrylic burs
 Sand Paper
Take care not to generate much heat during polishing to avoid warpage of the acrylic
denture base.
