Initial situation of 1.2 old infiltrate restoration. Isolation with the rubber dam is mandatory to create an aseptic and dry environment and improves manual control together with efficiency.

Remove all the old composite and clean the tooth of caries lesion.

We made the proximal wall placing the composite following the matrix. First we reproduce the mesial wall to make it easier the restore of palatal wall with only one mass of composite.

Only single mass to restore the palatal and vestibular parts of the teeth.

Modeling the surface to reproduce the secondary anatomy.

The final result after remove the rubber dam.

Close-up view of the central incisors. Midline diastema closure was desired for esthetic reasons.

Situation 15 years after the initial non-prep treatment with composite. The restorations are still intact, but there is room for improvement with regard to the shape especially in the vestibular area.

Material selection: The preferred material for the single-shade technique sufficient here is 3M™ Filtek™ Universal Restorative in the shade A1. The composite is available in a universal opacity and shows a beneficial chameleon effect.

Appearance after the application of the first composite layer. The idea was to cover the vestibular surface for improved surface texturing and to reduce the space between the teeth. This enabled to place two contoured posterior sectional matrices.

Lateral view: Composite material is applied to fill the space between each central incisor and the adjacent matrix. The shape of the matrix facilitates the establishing of a tight contact point and the desired anatomical form.

Close-up view of the maxillar incisor. The restorations are well integrated to the natural tooth structure. Proximal opalescence was decided to remain intact and a blue halo can be perceived.

Initial situation. 1.1 and 2.1 fracture and old composite infiltration. We made a pre-operatory restoration placing a composite without etching the surface to create initial and ideal anatomy for prepare a silicon mold guide.

Put only one layer of composite into the mold guide.

This picture show the perfect matching the color offer by only one layer of composite and a good anatomy with the silicon mold.

Restoration polymerized after removed the silicon guide.

Continue placed the same shade composite used before to finishing the restoration.

The final restoration before finishing and polishing.
