The document outlines the steps involved in making a removable partial denture: 1) Impressions are taken of the patient's mouth to create a model. 2) A framework is designed and fabricated to hold replacement teeth. 3) Teeth are arranged and wax is used to form the denture base. 4) The wax denture is invested, processed, and polished to create the final removable partial denture. The process takes 3-6 weeks and several appointments.

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

4. The denture development process takes about three to six weeks and several
appointments. Once your dentist or prosthodontist (a dentist who specializes in
the restoration and replacement of teeth) determines what type of appliance is
best for you, the general steps are :
 Impressions
 Model Preparation
 Survey
 Framework
 Waxing
 Setup
 Flasking
 De-waxing
 Application of
Separating media
 Packing
 Curing
 Deflasking
 Finishing &
Polishing

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.
