Flashcards

Why use resin composite?

The trend of using resin composites instead of metal restorations, driven by patient preferences, advancements in dental materials, and concerns about mercury toxicity.

Challenges of posterior resin composites

The challenges of restoring posterior teeth with resin composite include high occlusal forces, wear, large cavities, achieving proper contact, technique sensitivity, and material handling difficulties.

Essential steps for success

Careful patient selection, proper cavity design, isolation techniques, wedging, and matricing all play a role in successful posterior composite restoration.

Why is isolation important?

Proper isolation helps prevent contamination and ensures accurate placement of the composite material.

Study Notes

Posterior Resin Composite Restorations

Esthetic resin composite restorations are replacing metal restorations due to increased patient demand, advancements in adhesive dentistry, and conservation efforts in cavity preparations.
Concerns for posterior composite restorations include heavy occlusal stress, proximal wear, large cavity size (high C factor), restoring proximal contacts, sensitivity to technique, and material handling difficulties.
Successful restoration relies on careful selection of patient and material.
Conservative cavity design is crucial.
Effective isolation is important for better adaptation.
Optimal wedging and matrixing are essential to reconstruct proximal contacts and marginal ridges.
Effective bonding results in seamless marginal and internal adaptation, preventing postoperative sensitivity.
Correct composite application ensures proper reconstruction of missing contours.
A long-lasting, polished surface finish improves restoration longevity.
