case report

A 28-year-old female patient, without any systemic medical conditions presented with a carious lesion affecting both molar 46D and 47M. The following case illustrates the direct composite restoration of the lesion using the Polydentia QuickmatFIT anatomical sectional matrices in combination with myRing Forte and myWedge plastic v-shaped wedges.



1: Pre-operative x-ray showing a carious lesion affecting both molar 46D and 47M



2: Pre-operative view of quadrant 4 under isolation; pre-wedging was carried out using a wooden wedge to facilitate the placement of the sectional matrices.

3: The cavities after caries removal, cleaning and disinfection.



4: Matrixing: two QuickmatFIT molar matrices were placed on 46D and 47M to seal the cavities. For effective tooth separation, myRing Forte was positioned before proceeding with the proximal walls restorations.  The anatomical contouring of the QuickmatFIT matrices results in two main benefits for the dentist: increased rigidity of the matrix itself, making it easier to position, and improved adaptation to tooth morphology, requiring less finishing of the composite filling.

5: Once the distal surface of Molar 46 had been restored, the myRing Forte and QuickmatFIT sectional matrix were removed.

6: The myRing Forte was then repositioned for the restoration of the mesial wall of Molar 47.

8: Modelling of the occlusal surfaces; a small amount of brown pigments were used to reproduce stain.

QuickmatFIT sectional matrices from Polydentia combine a high-rigidity alloy with a unique three-dimensional profile, providing an easy solution to a number of difficult clinical situations. When used in combination with myRing Forte, the result is a reconstruction with an accurate and natural morphology, that reduces the time required for the finishing steps.
