    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.
