clinical case

The young patient came to our attention for the replacement of an old composite restoration and with an interproximal lesion on molar 36. The following images show the step-by-step direct composite restoration procedure using myQuickmat Forte kit (Polydentia) in combination with myTines Small and myTines Medium (Polydentia). myTines Small are very useful tools when restoring cavities in young permanent teeth featuring short crowns.

conclusion

Customisation of our sectional matrix systems with different extremities on the same separator ring gives improved stability of the ring even in posterior teeth with inclinations of their long axis. This characteristic offered by myQuickmat Forte sectional matrix system (Polydentia) results in natural-looking and functionally correct restorations.
