This document provides an introduction to prosthodontics, which is the branch of dentistry dealing with replacing missing teeth and oral structures. It defines key terms like prosthetics, prosthodontics, prosthesis, dentulous, and edentulous. The types of prostheses are outlined, including partial dentures, fixed partial dentures, removable partial dentures, and complete dentures. Reasons for tooth loss and sequelae of tooth loss are described. Finally, the various treatment options for tooth replacement are summarized, such as preservation techniques, crowns, implants, dentures, and maxillofacial prostheses.

1. INTRODUCTION TO
PROSTHODONTICS
By
Dr. Haitham Aboud
Lecturer of removable prosthodontics

3. DEFINITIONS
• Prosthetics:
• Replacements for missing parts of the human body.
• Prosthodontics:
• The branch of dentistry pertaining to the
restoration and maintenance of oral function,
comfort, appearance, and health of the patient.
• Prosthesis:
• An artificial replacement of absent part of human
body.

4. DEFINITIONS
• Dentulous:
• An individual who has his/her
natural teeth present.
• Edentulous:
• The individual who has lost his/her
natural teeth.
• Depending on the number of teeth
missing they may be partially or
completely edentulous.

5. Types of Prostheses
• Denture:
• A prosthesis which replaces the one or more teeth and related
structures in the mouth. Partial, complete, fixed or
removable.
• Partial denture:
• A dental prosthesis which restores part not all of the
dentition.
• Fixed partial denture:
• An artificial appliance designed to replace one or more of
missing natural teeth. The patient cant remove from the
mouth.

6. Types of Prostheses
• Removable partial denture:
• An artificial appliance designed to
replace one or more of missing natural
teeth. The patient can remove it from
the mouth.
• Complete denture:
• An artificial appliance replaces the
complete absence of natural teeth and
associated structures of the maxilla or
mandible (single denture) or for both
jaws together.

7. Why Edentulous Patient Must Restore His Missing
Natural Teeth
-To restore the function of mastication
-To improve speech and cosmetic appearance.
-To avoid abnormal masticator habits that lead to
TMJ disorders.

8. Reasons for tooth loss
• Traumatic injuries
• Caries
• Periodontal diseases
• Cysts, malignancies and tumors
• Radiation therapy for tumors
• Grossly malaligned teeth
• Iatrogenic extraction
• Congenitally missing teeth
• Failure to erupt (impacted teeth)

9. Sequelae of tooth loss
• Resorption:
• The socket gradually remodels until it assumes the
shape of the rounded edentulous ridge.
• Tilting
• Drifting
• Occlusal disharmony leads to discomfort, pain, or
damage to temporomandibular joints.

10. Sequelae of tooth loss

11. Treatment Options
• Preservation and prevention
• Post and core/crowns

12. Treatment options
• Implants

13. Treatment options
Fixed partial dentures

14. Treatment options
• Removable partial dentures

15. Treatment options
• Overdenture

16. Treatment options
• Complete denture

17. Treatment options
• Implant retained denture

18. Treatment options
• Maxillofacial prostheses
Make prosthetic replacements of
other areas of the mouth and face
lost by disease and trauma
