clinical case
The patient came to our practice for the aesthetic modification of multiple diastemas and defective restorations between teeth 11-21 and 21-22; we also took the opportunity of the treatment to improve the overall aesthetics of the anterior region by applying multiple direct stratification composite veneers using Unica Proximal anterior matrices.

10: Unica Proximal anterior sectional matrices were then placed on 11M, 12M, 13M, 21D, 22D, 23D together to close the spaces and achieve reshaping from tooth 13 to tooth 23. The shape of the matrices allows for stable positioning, accurate proximal contour reproduction and good visibility due to the absence of excess material.

conclusion
Unica Proximal solves the problems of anterior matrices, by ensuring easy matrix placement, self-stabilisation without wedges, and outer contour prediction, as it fits the restored anterior teeth perfectly without labial and palatal matrix excess.
It is ideal for Class III and IV, diastema, reshaping, and composite veneer situations. Unica Proximal is a smart solution for everyday direct aesthetic and functional anterior restorations.
