clinical case
The patient came for a consultation complaining of discomfort at tooth 36 when chewing. Molar 36 presented a very old composite restoration with initial disto-occlusal infiltration.
We decided to carry out an OD restoration that also involved the buccal surface in order to replace the filling with a new aesthetic restoration.
In this clinical case, we illustrate the procedure for the step-by-step restoration of tooth 36 using the Polydentia QuickmatFIT Molar sectional matrix in combination with the myQuickmat Forte sectional matrix ring.

conclusion
The major innovation of the Polydentia QuickmatFIT Molar matrices, which are also available in a premolar version, is that they are even easier to handle and use. The three accessory tabs at both ends of the matrix and at the top simplify matrix placement and removal, as they are designed to be removed using dental forceps.
In addition, the Polydentia QuickmatFIT Molar matrices, in combination with the myQuickmat Forte sectional matrix ring, provide a competent contact point that ensures protection of the interdental space and prevents post-restoration food impaction.
