Study Notes
Connectors in Fixed Partial Dentures (FPDs)
- Connectors are parts of a fixed partial denture (FPD) or splint that join individual retainers and pontics together.
- There are two types of connectors: rigid (fixed) and non-rigid (flexible).
- Tissue surface of connectors must be highly polished and curved facio-lingually to facilitate cleansing and prevent plaque accumulation.
- Connectors should be placed as lingually and incisally as possible for self-cleansing.
- The depth of a connector should always be sufficient to provide adequate strength.
Soldering Gap Width
- As gap width increases, soldering accuracy decreases.
- Extremely small gap widths can prevent proper solder flow and lead to an incomplete or weak joint.
- An even soldering gap of about 0.25 mm is recommended.
Soldering of Post Ceramic
- Post ceramic soldering should be done after ceramic firing.
- Ceramic portions should be finished only after soldering.
Advantages of Soldering
- Good access to finish the margins on both the wax pattern and the casting prior to soldering.
Loop Connectors
- Loop connectors are rarely used and are used when the existence of diastema is to be maintained in planned fixed prosthesis.
Learn about the importance of tissue surface design in dental connectors, including polishing and curvature, to prevent plaque accumulation and facilitate cleansing.
