This document provides an introduction to removable prosthodontics and complete dentures. It defines prosthodontics as the branch of dentistry that replaces missing teeth and supportive structures through artificial devices like bridges and dentures. A complete denture is described as a removable dental prosthesis that replaces all of the missing teeth and associated structures in the edentulous maxilla and/or mandible, with the objectives of restoring function, speech, appearance, comfort and tissue preservation. The key steps in fabricating a complete denture are outlined, including taking a primary impression with stock trays and impression material, pouring a primary cast, and improving the oral condition of edentulous ridges.

2. What is Prosthesis???
Artificial appliance used to replace part of the body

3. Prosthodontic Dentistry
• Branch of dental art and science that replace
missing teeth and supportive structures (bridge,
denture) by artificial devices to restore and
maintain oral function.
Dental Prosthesis
• It is an art that replace missing teeth and
supporting dento-alveolar structures (gingiva –
PDL – Bone)

4. Conditions of the oral cavity:
1- Dentulous 2- Edentulous 3-Partially
edentulous

5. Prosthodontics
Fixed Implant
Removable Maxillofacial

6. Removable Prosthodontics
Complete Overdenture
Partial
Acrylic Cobalt-Chrome

7. Denture
Denture is an artificial replacement appliance
(removable) for missing natural teeth and
supporting structures (complete or partial).
Complete Denture
Is a dental prosthesis replacing the missing
teeth and associated structures of the
edentulous maxilla and / or mandible.

8. Complete Denture
Objectives:
- Function (mastication)
- Speech
- Appearance (Esthetics)
- Satisfaction and comfort
- Tissue preservation

9. Denture Surfaces
1- Impression, tissue or fitting surface
Surface recorded by
impression and fitted
to mucosa and
extended to the
border of denture.
2- Occlusal Surface
The surface that
occlude with
opposing denture or
natural dentition.

10. 3- Polished surface:
-Highly polished surface.
-Extended from borders to occlousal surface

11. Denture border
The margin of the denture base at the
junction of the polished surface with fitting
surface.
It must be rounded and smooth.
Denture flange
It is the vertical extension of the upper and
lower dentures.

12. Patient
1- History and examination:
a) Extraoral
b) Intraoral

13. 2- Treatment plan
3- Improvement of oral condition:
e.g old denture

14. Complete denture
1- Primary impression (preliminary):
stock trays
Impression material

15. 2- Primary impression:
Compound impression material

16. Rubber
bowel and
spatula

17. Mixing the
dental stone
