Immediately after finishing the final preparation, it was necessary to restore the palatal wall of tooth 2.5. For this, I used a “3D printer” layering technique, gradually rebuilding the wall with a flowable composite (Estelite Universal Flow). The thickness of each increment did not exceed 1 mm — in total, I placed 8 increments.
Next, I adapted the matrix to restore the contact point of tooth 2.5 using composite “buttons” made from flowable material. It is essential to bond these buttons to matte surfaces (the wedge, rubber dam clamp, tooth surface, etc.) to ensure better stabilization.
After restoring tooth 2.5 (using Asteria A2B + EverX Bulk Fill / NeoSpectra HV A2), I proceeded with restoring the contact of tooth 2.4 using a sectional ring and composite buttons.
Polishing: removal of the oxygen-inhibited layer with calcium carbonate, followed by Diacomp Twist and a white brush without paste.
Total treatment time: 2 hours.
