When should composite resin restorations be finished?

Composite resin restorations should be finished immediately after curing to achieve optimal results. This timing is essential for a few reasons. First, freshly cured composites are still in a relatively malleable state, allowing for more precise finishing and contouring without risking damage to the restoration or the surrounding tooth structure. Immediate finishing also facilitates better adaptations to the restoration margins, ensuring a smoother transition between the composite and the tooth, which is crucial for the longevity and aesthetics of the restoration.

Moreover, while the material is still soft, the finishing process can be accomplished with minimal friction, reducing the risk of generating excessive heat that can occur with prolonged polishing or finishing. This helps to preserve the integrity of the composite material and prevents potential thermal damage.

Waiting a period of time (like 1 hour, 24 hours, or even a week) can lead to difficulties in achieving the desired shape or polish since the composite may become harder and less workable, making it more challenging to achieve an ideal finish. Thus, finishing immediately after curing is considered best practice in dental restoration procedures with composite resin materials.
