Tooth decay continues to be a disease that affects a large portion of the world’s population. The need for anterior composite restorations is increasing day by day as patients pay more attention to their aesthetic appearance. Composite resins have gained quality as a restorative option thanks to their aesthetic properties and minimal invasiveness. Various composites are available as a preferred option for restoration of anterior teeth. However, it has been shown that teeth with severe material loss are associated with a higher likelihood of restoration failure due to the longer time required to place the restoration. Anterior restorations produced with 3D printers may be a new treatment alternative for teeth with severe crown destruction, especially in children.
The current case presented a 3D-printed Crown and Direct Composite Restorations in Anterior Teeth.

Conclusions

3D-printed restorations are emerging as a dependable option for single crowns. It is crucial to factor in the capability to color and enhance aesthetics with composite materials or characterization coatings.
