Flashcards

What is the C Factor in restorative dentistry?

The ratio of the bonded surface area to the unbonded surface area of a cavity preparation. A high C-factor means more unbonded surface, making the restoration more prone to shrinkage stress and potential failure.

What is wedging and matricing in restorative dentistry?

Using a wedge and matrix to create a proper interproximal contact and contour for a restoration. It prevents food impaction and maintains proper tooth alignment.

What is the importance of optimal bonding in resin composite restorations?

The ability of the resin composite to tightly adhere to the tooth structure. It ensures a strong bond and minimizes leakage that can lead to sensitivity and failure.

Why is surface finish and polish important for resin composite restorations?

The process of creating a smooth, polished surface on a resin composite restoration. It improves the aesthetics and prolongs the life of the restoration by minimizing plaque accumulation and wear.

What is the trend of replacing metallic restorations with resin composite?

The replacement of non-esthetic metallic restorations with esthetic resin composite restorations. It is driven by patient demand, advancements in adhesive dentistry, and mercury toxicity concerns.

Study Notes

Posterior Resin Composite Restorations

Esthetic restorations are replacing metallic ones due to patient demand, advancements in adhesive dentistry, and conservation in cavity preparations. Concerns about mercury are also significant.

Challenges in Posterior Resin Composite Restorations

Posterior teeth face high occlusal forces.
Proximal wear is a common issue.
Large cavities (high C factor) are difficult to manage.
Restoring proximal contacts is crucial.
Resin composite manipulation can be sensitive.
Accessibility issues are common in certain situations.

Successful Posterior Resin Composite Restoration

Proper patient and material selection is essential.
Conservative cavity designs are ideal.
Effective isolation improves adaptation.
Optimal wedging and matrixing rebuilds proximal contacts and marginal ridges.
Robust bonding ensures optimal marginal and internal adaptation, preventing hypersensitivity.
Accurate resin composite application restores lost tooth contour.
A long-lasting surface finish and polish increases the restoration's longevity.
