Flashcards
Why are composite restorations replacing metal fillings?
Why are composite restorations replacing metal fillings?
Replacing metal fillings with tooth-colored composite resin to meet patient preferences, promote conservation, and address mercury concerns.
What's the challenge of occlusal stress on posterior composite fillings?
What's the challenge of occlusal stress on posterior composite fillings?
Posterior teeth are subjected to high chewing force. This can lead to composite fillings wearing down or breaking.
What is the C factor in dentistry?
What is the C factor in dentistry?
The C factor is the ratio of bonded to unbonded surfaces in a cavity. A high C factor means more unbonded surfaces, which can weaken the filling.

Study Notes
Posterior Resin Composite Restorations
- Esthetic restorations are replacing metallic ones due to patient demand, advancements in adhesive dentistry, conservative cavity preparations, and mercury toxicity concerns.
Challenges in Posterior Resin Composite Restorations
- High occlusal stress.
- Proximal wear.
- Large cavity preparations (high C factor).
- Reconstructing proximal contacts.
- Resin composite's technique sensitivity.
- Resin composite's handling difficulties (limited accessibility).
Factors for Successful Posterior Resin Composite Restorations
- Appropriate patient and material selection.
- Conservative cavity design.
- Effective isolation techniques.
- Optimal wedging and matrixing for proximal contacts and marginal ridges.
- Perfect bonding for marginal and internal adaptation, preventing postoperative sensitivity.
- Accurate resin composite application to reconstruct the lost tooth contour.
- Long-lasting surface finish and polish for extended restoration lifespan.
