The document discusses fixed prosthodontics, focusing on various types and classifications of fixed dental bridges used to replace missing teeth. It describes different bridge types based on design, retention, material, span length, and other criteria, including components like retainers and pontics. The document includes contributions from several dental students.

- 2. FIXED PROSTHODONTIC 1. Dental Crown 2. Dental Bridge 3. Inlay 4. Onlay 5. Veneer
- 3. FIXED DENTAL BRIDGE • Is the branch of Prosthodontics, that deals with the replacement of missing tooth or teeth using an artificial substitute that permanently cemented in place .
- 4. TYPES OF FIXED DENTAL BRIDGE
- 5. 1- TRADITIONAL TYPES A. Fixed Fixed Bridge B. Fixed movable Bridge C. Fixed removable Bridge (Andrews' bridge)
- 6. 2 - Resin Bounded Bridge : A - Maryland Bridge B - Rochate Bridge
- 7. 3 - Cantilever Bridge and Spring cantilever . 4- Implant Support Bridge .
- 9. ACCORDING TO POSITION • 1- Anterior FPD : It extends only between the anterior teeth , doesn't cross or cross the midline . ( central , lateral , canine ) • 2- Posterior FPD: It extends only between the posterior teeth . ( molar , premolar ) • 3- Complex FPD: It extends at one of its terminals beyond the canine .
- 10. ACCORDING TO RETENTION • 1- Simple bridge : it is one single bridge, and it may be : 1- Fixed- Fixed : which is fixed at both ends to the abutment teeth. 2- Fixed- Supported : which is connected to one of the terminal abutment teeth by a non-rigid connector to allow some individual movements of the patient.
- 11. CONT . • 2- Cantilever and Spring cantilever * Cantilever : which is a free-end bridge, where the pontic is fixed to and derives its support from one or double retainers at one end only and the other end is unsupported. * Spring cantilever bridge : which is a cantilever bridge, where the pontic is at the end of slightly resilient curved arm deriving its support from an abutment tooth remote from edentulous space.
- 12. CONT . • 3-Compound bridge : it is a combination type of bridge, contains more than one type of simple bridge .
- 13. ACCORDING TO MATERIAL • 1- Metallic : a - precious alloy . b - semi precious alloy . c - non precious alloy . • 2 - non metallic : all resin , all ceramic . • 3- Combined : metallic with labial or buccal veneers metallic with lingual .
- 14. ACCORDING TO THE LENGTH OF SPAN • 1- short span ( one missing tooth ) • 2- medium span ( two missing teeth ) • 3- long span ( more than two missing teeth )
- 15. ACCORDING TO THE CHRONOLOGY OF SPAN • 1 - Provisional bridge . • 2 - Temporary bridge . • 3 - immediate bridge . • 4 - Definitive bridge .
- 16. ACCORDING TO THE NUMBER OF TEETH MISSING AND THE NUMBER OF ABUTMENTS 1. Simple ( one missing tooth, two abutments ) 2. Complex ( two missing teeth, two abutments ) 3. Complex ( two missing teeth, more than two abutments ) 4. Complex ( Pier abutment )
- 17. COMPONENT OF FIXED BRIDGE Retainer Pontic Connector Abutmentresidual area
- 18. RETAINER • The part of a fixed dental prosthesis that unites the abutments to the remainder of the restoration.
- 19. PONTIC • An artificial tooth on a fixed dental prosthesis that replaces a missing natural tooth , restores in function, and usually fills the space previously occupied by the clinical crown.
- 20. CONNECTOR • The portion of a fixed prosthesis that unites the retainer and pontic
- 21. ABUTMENTS • it is a natural tooth or an implant used to support and retain the FPD at one or both terminals.
- 22. RESIDUAL AREA • The area in the gums for the missing tooth
